POWER GENERATION AND DISTRIBUTION
The Louisiana Division Power Plant No. 1 generates and distrubutes all its electrical power and steam. Steam is generated at 1250 psig and is extracted for process from three single automatic and one double auto matic extraction turbine. Distribution pressures are 475 psig and 235 psig. Electrical power is generated at 14.4 KV and is distributed at this voltage to Chlorine rectifiers, motor power substations, and river water pump stations. Excitation for the Generators 1 and 2 is by means of motor generator sets with a full capacity spare exciter available for use. This method of excitation allows for easy maintenance of commutators. Generators 3 and 4 are provided with static exciters with provisions for using the spare motor-driven exciter.

WATER SUPPLY AND TREATING EQUIPMENT
I.Supply
The source of all water used in the Louisiana Division except for fire fighting is the Mississippi River. The water is pumped into a distri bution canal, from which the various plants take their supply for cool ing purposes.
II. Clarification
The Water Treating Plant takes raw river water from the distribution canal and treats it for various uses. The water is clarified in two (2) 7500 gpm units and two (2) 10,000 gpra units, by treatment with cationic polyelectrolyte and an anionic aid . This water is distri buted to the filtration plant and to the process plants.
Ill. Filtration
The portion of process water that flows to the filters is filtered through four rapid sand filters then chlorinated. This effluent is used as potable water. Water for the demineralizer plant is filtered through three (3) pressure filters.
IV. Demineralizer Water
The pressure filter effluent is dechlorinated prior to entering the demineralizer units. After demineralization the water flows to the Power Plant's two (2) 500,000 gallon condensate storage tanks.
