All natural water contains various types and amounts of impurities. Since water impurities cause problems in a cooling system, careful consideration must be given to the quality of the water used for this purpose. Water is an excellent solvent; it dissolves the rocks and soil it contacts. It absorbs gases from the atmosphere and the soil it contacts. It picks up suspended matter as it runs across or percolates through the ground. In general the type of impurities water contains depends on what it contacts, and the amount of impurities depends on contact time. The impurities which water picks up can be put into three broad groups: 1. Dissolved solids 2. Suspended solids 3. Gases CONFIDENTIAL: Subject to Protective Order of 14th Judicial District Court No. 91-1145 3 DISSOLVED SOLIDS The impurities ( minerals in a dissolved state ) which water picks up consist chiefly of calcium carbonate, calcium sulfate, magnesium sulfate, silica ( sand ), sodium chloride, sodium sulfate, and small quantities of iron, manganese, fluorides, aluminum and other substances. SUSPENDED SOLIDS Natural water may contain turbidity, color, soil, and precipitated minerals. In addition, water can contain other wastes. Turbidity may consist of very finely divided organic mater, minerals and microorganisms as well as suspended clay and silt. Color comes from decaying vegetable matter. Wastes can be oil, fats, greases, and sewage as well as a variety of effluents from many different sources. GASSES Gases (primarily carbon dioxide and oxygen) are absorbed from the air by water as it falls to earth. Additional carbon dioxide and oxygen are picked up from decaying matter in the soil as the water runs across and percolates through the soil DISSOLVED SOLIDS Calcium Magnesium Silica Iron Manganese Sodium Chloride Sulfates Fluorides Carbonates Bicarbonates Aluminum SUSPENDED SOLIDS Soil Decaying vegetable matter Precipitated minerals Oil Trade waste Microorganisms Clay GASES Carbon Dioxide Oxygen Others 4 Fresh water supplies are grouped into two categories: (A) ground water and (B) surface water. Some of the water reaching the ground seeps down through the surface to form the under-ground streams and lakes. A portion of the water reaching the earth's surface runs across the soil then into brooks, streams, bayous, rivers, ponds or lakes. The former is referred to as ground water, the latter as surface water. Because ground water (shallow and deep wells) is in contact with the rocks and soil for a longer period of time (in percolating down through the various layers of soil and rock) it will contain a higher amount of dissolved solids than surface water. Surface water on the other hand will contain a higher amount of suspended solids. As pointed out earlier, the types of impurities found in water depend on what the water contacts, the amount that it contains depends on the contact time. One way to measure the amount of dissolved solids in water is Conductivity. The dissolved salts conduct electricity through the water. The greater the dissolved solids load, the greater the amount of electricity the water will conduct. One measure of suspended solids in water is Turbidity. The sabine river water used in the Lake Charles plant is clarified in the Sabine water clarification unit operated by the Plant C powerhouse operators. They use treatment chemicals to remove the suspended solids. They measure the turbidity of their outlet water. They also chlorinate the water. SL 002511 CONFIDENTIAL: o 'tt".iiv_ Ve order strict Court 5 Waters which contains large amounts of calcium and magnesium are referred to as Hard water. The amount of hardness in natural water may vary from several parts per million to over 500 parts per million. 1 part per million is 1 pound per 1,000,000 pounds, and is abbreviated ppm. An average surface supply will contain about 95 ppm total hardness as opposed to an average of about 200 ppm for ground water supplies. In the Lake Charles complex the surface water we use is clarified Sabine river water, and it has a total hardness of about 25 to 30 ppm, which is below the average. Since hardness (calcium and magnesium) is relatively insoluble in water, it tends to precipitate (fall out) of solution and form deposits in the cooling water system. While all impurities found in water must be taken into consideration when used in a cooling system, special attention must be given to the hardness present. SL 002512 C ofSu1b43tiev ctjuaic;.' lc.u COOLING WATER SYSTEMS 6 Simply stated, a cooling water system absorbs heat from one area and dissipates it into another area. There are a number of types of cooling water systems. There is the spray pond, the once through system, the refrigeration system and the cooling tower system. Each of these systems has their own treatment problems. The cooling tower system works by mixing warm water with cool air. The heat transfer is accomplished partially by a transfer of sensible heat which raises the temperature of the air. The majority of the cooling is due to an exchange of latent heat resulting from the evaporation of a small part of the circulating water. All cooling towers have the same basic function, to break up the water into droplets and move air across them. These functions result in a more efficient evaporation of water and in that process, dissipation of heat from the system. There are two ways in which the tower can break up the water into small droplets. One involves the use of spray nozzles in the tower, the other relies on splash plates. As the water falls from the top of the tower it hits the splash plates and small droplets are formed. The tower can draw air across the water droplets by either natural convection or forced draft. The towers in the Lake Charles plant are all forced draft. A fan forces air across the water droplets to aid in evaporation. SL 002513 7 Because water is evaporated from the system, water must be added to the system. This fresh or makeup water has some of the impurities pointed out earlier. As water evaporates, it leaves as pure water vapor. The impurities stay behind in the recirculating water stream. As the impurities increase in concentration they will reach a point where they cannot stay in solution. ' They will precipitate out and cause problems through out the process equipment serviced by the water. The impurities Cycle up. that is their concentrations in the tower water increase to double or triple their concentration in the make up water. When their concentration becomes double that of the make up we say the tower is running at 2 cycles. The TETRA and PER/TRI towers should run at 7 cycles. The lower the number of cycles the more treatment chemicals that must be added to maintain the proper level for corrosion or scaling control. The method of removing the impurities that accumulate in the cooling tower system is called Blowdown. Blowdown is the intentional or unintentional purging of water from the system. Blowdown should be done from the warm inlet side instead of the cool outlet side. Like wise make up should be added to the cooler basin water. The make up on the TETRA and PER/TRI towers is controlled by a LCV and LT on the tower basin. The blowdown is manually controlled using the conductivity of the recirculating water.

The heat exchanger may be a direct contact type as with a barometric condenser. It may be a shell and tube type of exchanger, where the water is on one side and the process is on the other side. A lot of the exchangers on the TETRA and PER/TRI cooling towers have the water on the tube side of the exchanger. This helps maintain good water velocity through the tubes and helps prevent suspended solids from settling out. When the water is on the shell side of the exchanger solids can settle out in the low velocity areas. We will speak later of the problems this can cause. There are some designs that allow the shell side of an exchanger to be cleaned easily, such as with a removable bundle. If the distance between the tubes and the geometry of the tubes allow, full cleaning is possible. Some exchanger designs prevent adequate cleaning by any method. These are sometimes found in refrigeration units. Whenever possible tube side'water is better from a cleaning standpoint.

As we have already seen water contains solids which if not controlled and treated can precipitate and form scale. The gases in make up water plus gases which can be carried into the tower by the air draft are corrosive. Airborne contaminants such as dust and silt can be drawn into the tower cooling water. Biological growths such as algae, slime forming bacteria, fungi and other microorganisms can breed readily in cooling water systems. Alone or in combination, the solids, gases, airborne contaminants or microorganisms can cause serious problems in the efficient operation of a cooling system. SL 002516 CONFIDENTIAL: Subject to Protective Order of 14th Judicial District Court No. 91-1145 SCALE 10 Scale deposits One of the most serious problems which can develop in untreated cooling tower water is that caused by scale. Scale formation occurs when the solids and gases in the cooling tower water reach their limits of solubility and precipitate out onto piping and heat transfer surfaces. As the scale deposits on heat transfer surfaces, the ability of the cooling tower water to absorb heat is reduced. This results in reduced capacity and higher power consumption. Prevention of Scale Scale prevention is a twofold approach: (A) Chemical treatment is added to the cooling tower water which retards or delays solids from precipitating out and forming scale. (B) While treatment chemicals increase the solubility of solids in water so they stay in solution, a point is reached where they will precipitate (their solubility has been exceeded). When this point is reached the system must be bled. The control of scale then involves both chemical treatment and the limiting of solids through "bleed". SL 002517 Protctive Order 14th Judicial District Court No. 91-1145 CORROSION 11 Causes of Corrosion Corrosion is simply the eating away of metal. It is actually a chemical reaction between the metal in the system and the recirculating water. Three types of corrosion can take place in a cooling water system. (A) General corrosion is when the corrosion attack is uniform and lightly distributed over the entire area of the metal. (B) Pitting corrosion exists when a large part of the area is protected and only a small localized area is attacked. Pitting is considered more objectionable since a large corrosive force is concentrated in a very small area and rapid penetration and failure may result. (C) Galvanic corrosion is the third type of corrosion encountered. This can occur when dissimilar metals are in contact with each other. Conditions which foster corrosion are high oxygen concentration, high temperature, high velocity of liquid on the metal surfaces, low pH, high soluble sulfates and chloride concentration and galvanic action. SL 002518 CONFIDENTIAL: Subject to Protective Order of 14th Judicial District Court No. 91-1145 Prevention of Corrosion 12 The prevention of corrosion usually requires one or more of the following approaches: (A) Treatment of the water to make it less aggressive such as adjustment of the pH. (B) Developing a protective coating by film-forming chemicals added to the cooling tower water. They are recirculated in the water and deposited on the system metal. The is a measure of the acidity or alkalinity of a solution. It is based on a scale of 0 to 14. The mid point of the scale is 7. Solutions which measure 7 are said to be neutral, neither acid or alkaline. Solutions which measure between 0 and 7 are acid, and those between 7 and 14 are alkaline, Since pH is a logarithmic function, solutions having a pH of 6, 5, and 4 are 10, 100, and 1000 times more acidic than one with a pH of 7. Sl 002519 CONFIDENTIAL: Subject to Protective Order of 14th Judicial District Court No. 91-1145 FOULING 13 Airborne Contaminants Contaminants scrubbed from the air as it passes through the tower can result in fouling of heat exchangers, condensers, piping and tower packing. The most common type are those which leave a silt like deposit. These fall under the general heading of suspended solids. They can also enter the system through the makeup. The deposits can build up and retard heat transfer, restrict water flow, promote corrosion and harbor microorganisms. Chemical treatment (synthetic polyelectrolytes are most commonly used) to prevent accumulation of silt is added to the cooling tower water. These polymers serve to agglomerate the silt particles and bind them into loose but coherent larger masses. The effect is to keep these larger particles suspended and remove them during "bleed". Fouling from inorganic deposits can easily happen in low flow or low velocity areas of the system. This can happen on the shell side of exchangers. When deposits start to grow, underdeposit corrosion can start and the deposit protects the corrosion cell from the passivating effects of the treatment program.

These compounds help form a protective coating in the cooling tower system. It also contains dispersants and polymers to help keep some of the impurities in solution, and prevent them from precipitating out of solution. The component of Mazplex MO that will be monitored by chemical analysis is the Molybdate. Maztreat 838 is a solution of Tolytriazole. This is a premium copper / copper alloy corrosion inhibiter. This is a compound common in automobile radiator rust inhibitors. The PPG/Mazer representative will monitor the level of this component in the tower. Mazsperse 830 is a mixture of two powerful dispersants. They are helpful m extending the solubility of iron, zinc and other dissolved sol ids. They also help condition the suspended solids so they may be purged from the system in the blowdown. SL 002522 CONFIDENTIAL*- order trict Court PPG/Mazer treatment chemicals cont. 16 Mazide BC 915 is a Glutaraldehyde solution. This is a powerful biocide, algicide. It is fed to the system on a slug basis. The amount fed to the system should bring the glutarald hyde concentration up to 30 ppm. Mazide Br-cl is l-Bromo-3~Chloro-5.5-dimethylhydantoin (BCDMH). It is used in the system to help destroy any biological growths. It is called an oxidizing biocide. These growths were explained in an earlier section of this manual. When BCDMH dissolves in water HOBr and HOC1 are generated. The HOC1 is called hypochlorous acid, and the HOBr is called Hypobromous acid. C5H6BrClN;0* + 2H20 --> C5H8Nj02 + HOBr + HOCl They are Hypohalous acids and are the actual biocides. They can penetrate the cell membrane of the organism. A further reaction also occurs: HOCL = H* + 0C1' and HOBr = H* + OBr' SL 002523 CONFIDENTIAL: Subject to Protective Order of 14th Judicial District Court No. 91-1145 17 The OCL" and OBr' ions are not very good at killing bioorganisms. These reactions are pH dependant. In the pH range of the Tetra and Per/Tri towers the more predominate specie will be the HOBr.

The number of cycles will run low, maybe as low as 2 to 4. When a Sabine river water supply outage is planned, the Mazsperse 830 should be started two days ahead of time.

The lower pH sabine river water should help reduce the pH. The high pH can cause the zinc and iron in the system to precipitate out. Purge at all bleed points in the system to see if there is any milky or colored water in the system. The Mazsperse 830 should be turned on to 1/2 gallon per day and 3.5 gallons should be shot fed after the pH is back down to normal. The Mazsperse 830 can be turned off after one week.

It also dissolves iron and other yellow metals. The pH must be restored as soon as possible. The blowdown valve should be opened fully and the make-up opened. The dissolved solids must be purged from the system before redeposition can occur. If the pH cannot be restored within one hour soda ash should be added to the system. CAUSTIC SHOULD NEVER BE ADDED AS IT CAN CAUSE AN IRON HYDROXIDE FLOC TO PRECIPITATE OUT. IT IS EASY TO OVERSHOOT USING CAUSTIC. When the pH has been restored triple the Mazplex MO, and Maztreat 838 feed rates. They may be reduced to normal levels when the Molybdate level has recovered to 10 ppm. 3.5 gallons of Mazsperse 830 should also be shot fed after the pH is back up.

Loss of Blowdown If the blowdown valve sticks and the cycles go up above 8, the make up valve should be opened to allow fresh water into the system. Blowdown should be started at any place possible in the system. The blowdown should continue until the cycles are back down to 7 or below. The Mazsperse 830 should be started at 1/2 gallon per day rate, or shot fed after the cycles are back down to normal. Turn off the Mazsperse 830 after 48 hours.

The first way is for the sprinkler system to trip within the tower. The second way is for the level to get too low in the clear well in the Sabine River water clarification unit. When the sprinkler system in the cooling tower is tripped, fire water from the raw water impoundment at Sabine water clarification unit is pumped into the tower. The fire water lines are not purged very often and a lot of iron builds up in them. The fire water pumps take their suction from the old sportsman lake, and they bring up a lot of silt and other suspended solids. These suspended solids and iron must be removed from the system before they can settle out. When the level goes low in the clearwell at the sabine water clarification unit, a set of gates open to admit raw water. This water will have lot of suspended solids. Again as above, these suspended solids must be purged from the system before they can do any damage. In either case above, the cooling tower system must be purged by opening the blowdown valve and letting the make up valve open. The bleeds at each exchanger should be blown down.

SL 002532 ufidektiJ*'5 High or Low Halogen 26 If the Halogen level in the tower goes up, and stays up for a prolonged period of time, it can cause damage to the wooden structure of the cooling tower. The water should be halogenated to between .2 and .5 ppm as total chlorine. If the halogen level goes up above 1 ppm for any length of time, a reason should be sought. There could be several reasons for high or low Halogen in the tower. The flow through the Brominator should be checked. If the halogen level (Clj level) is low, the flow through the brominator should be raised. If the halogen level is high, the flow through the brominator should be lowered. The make up water from the sabine river water clarifiers is chlorinated before it is pumped into the distribution system. Check with the operators at Power House C to see if they are having a problem with the chlorinators at the clarifiers. High chlorine from the clarifiers can depress the system pH also. Sodium Thiosulfate can be added to reduce the chlorine level if necessary. This will be necessary only on very rare occasions.

They are somewhat different than other positive displacement pumps. They have no rotating armature in their motor. The power end of the pump is a vibrating armature. The diaphragm is attached to the armature. There are ball type check valves in the suction and discharge. This type of pump can be dead-headed without damaging the diaphragm. The vibrating armature simply will not be able to overcome the pressure on the discharge side and it will stop. It will restart when the discharge side pressure is reduced to normal. Setting the flow with these pumps is a simple matter. The pumps are rated for either 18 gpd or 14 gpd. The % speed and % stroke are a percentage of the 18 gpd or 14 gpd. If the % speed is set to 45% and the % stroke is set to 75%, the flow delivered by the pump will be 18 x .45 x .73 = 6gpd, in the case of the 18 gallon per day pump. In the case of the 14 gallon per day pump, a high range and low range % speed are available. The high range % speed covers 100% down to about 12%. The low range covers 12.5% down to 1%. In the high range % speed scale the pump flow is variable from 14 gpd to about 1 gpd. In the low range % speed scale the pump flow is variable from 1 3/4 gpd to about .05 gpd.

The larger the volume of sample caught, the more accurate the measurement. Divide the volume by the elapsed time to get mL/min. Multiply the flow rate in mL/min by .3804 to get gallons per day. Lf^r - SL 002540 CONFIDENTIAL: BROMINATOR 34 The amount of Halogen (read as Chlorine) in the cooling tower system is dependent on the water temperature and flow through the brominator. For this reason care should be taken to make sure water flow is always maintained. The water inlet line has at least one "Y" strainer in it. If flow is lost, the strainer should be taken out and cleaned. Because Halogen demand (Chlorine demand) can vary greatly, there is not a direct relationship between water flow and total halogen in the tower. There is a direct relationship between water flow and pounds of Mazide Br-Cl used. Refilling the Brominator To maintain accurate dispensing rate performance, refill the Brominator when it reaches half-capacity. The following steps describe how to fill the Brominator. Safety note: Always wear appropriate personal protective equipment when filling or servicing the Brominator. This should include rubber gloves and chemical safety goggles. Do not get Mazide Br-Cl in eyes or on skin or clothing. In case of contact with eyes or skin, flush thoroughly with water.

HEALTH HAZARD DATA Thresh Id Limit Value: 0.2 ppmv, ceiling Effects of Overexposure: Contact with skin or eyes will cause temporary irritation. Effects of a Single Overexposure: Swallowing: May cause moderate to severe irritation or burns of the mouth, throat, esophagus, and stomach, with abdominal and chest discomfort or pain, nausea, vomiting, diarrhea, dizziness, faintness, weakness, circulatory shock and collapse. Skin Absorption: Toxicology studies Indicate that prolonged or widespread c ntact could result in the absorption of potentially harmful amounts of material. Skin Contact; Brief contact will cause local reddening and swelling. More prolonged contact may result in severe inflammation and possibly skin burns. Eye Contact: Liquid will cause severe conjunctivitis and marked corneal Injury. Vapor may cause stinging sensations in the eye and excess lachrymation but not injury. Inhalation: Vapor is irritating to the respiratory tract causing stinging sensations in the nose and throat, coughing, chest discomfort and tightness, difficulty with breathing, and headache. Effects of Repeated Overexposure: May cause skin sensitization in a small proportion of individuals, and presenting as a typical allergic contact dermatitis. Emergency and First Aid Procedures: Flush eyes with copious amounts of water for a minimum of 15 minutes. Wash contacted skin areas with soap and water. If irritation develops, consult a physician. Soaked clothing should be changed immediately! Remove to fresh air. Ingestion-DO NOT INDUCE VOMITING. Do not give anything to to drink. Obtain medical advice with urgency. Significant Laboratory Data with Possible Relevance to Human Health Hazard Evaluation: Laboratory studies have shown glutaraldehyde is not teratogenic, and in vitro studies have demonstrated an absence of mutagenic effects. Medical Conditions Aggravated by Overexposure: May aggravate existing dermatitis. NOTES TO PHYSICIAN: Moderately toxic perorally and by sustained contact. Most of the adverse effects are due to the intensely irritating nature of this material. Due to its' corrosive effects on mucosal surfaces, any material aspirated during vomiting may cause lung injury. Thus, induction of emesis is NOT recommended. If evacuation of stomach contents is considered necessary, the means least likely to cause aspiration should be undertaken (i.e., gastric lavage in the presence of endotracheal Intubation). Due to irritation and possible ulceration of the upper alimentary tract, there may be blood and fluid loss resulting in electrolyte and fluid imbalance. Also, large swallowed volumes could result in perforation of the esophagus or stomach, causing mediastinltls r peritonitis and complications thereof.

Cary Brazitis September 29, 1991 Prom': Charles Long Subject: Cooling Tower Chemical Pumps Th LMI pumps used with the cooling tower treatment chemicals are positive displacement pumps. They have no rotating armature in th ir motor. The armature part of the motor in these pumps moves in and out like the solenoid part of a solenoid valve. A diaphragm is attached to the armature. There are ball type check valves in the suction and discharge ports of the pump head. This type of pump can be dead-headed without damaging the diaphragm because the motor is not as strong as the diaphragm. The pump will just stop pumping when dead-headed and will restart when the discharge side pressure is returned to normal. These pumps have two main controls on them. One control is for the speed, and the other controls the length of stroke of the motor armature. The speed controller is the small knob and the stroke controller is the larger knob. You should adjust the flow from these pumps using only the speed knob. Your service representative will adjust the stroke knob if necessary! A high and low speed range are available using the toggle switch in the upper left corner of the pump. The Mazplex MO pump should normally be used on th high range speed setting, while the Maztreat 838 pump should be us d on the low range speed setting. Setting the flow with these pumps is a simple matter, and can be done by measuring the amount of liquid pumped during a certain length of time such as one minute. You will need to us a stopwatch and graduated cylinder. Divide the volume, measured in milliliters, by the elapsed time, measured in minutes, to get ml/min. Multiply the flow rate in ml/min by .3804 to get gallons p r day. The Mazplex MO pump at TETRA should deliver about 1 1/2 to 2 gallons per day. This is 4 to 5 ml/min. The Mazplex MO pump at PER/TRI should deliver about 3/4 to 1 1/2 gallons per day. This is 2 to 4 ml/min. Routine adiustments to these pumps should be made in small amounts. A normal adjustment would be to raise or lower the speed bv 2%. A large adiustment would be 5%. During upsets, larger adjustment mav need to b mad . such as 10 to 20%.
