Do you go along with the state's pol lution-control requirements, or do you give up on the venerable plant and sell it? Last week, Allied Chemical Corp. made its decision: modernize the plant, which is on the Buffalo River at Buf falo, N.Y., and meet the state's require ments. The company is launching a $3.75million pollution-control project that has won the approval of New York state's Dept, of Health and the co operation of the Buffalo Sewer Au thority. .Allied -- which has already spent more than $65 million on pollu tion-control at its various plants--says this is its costliest pollution-abatement project to date. Separate and Unequal: The project was developed during the past three years by Allied and a consulting firm, ft has two main parts: a new system of trunk and lateral pipelines to pro vide separate outflows for the used cooling water and the waste water from the plant; and facilities to re habilitate the waste water so it can be handled in the city's own sewage-treat ment plant. The used cooling water (18.5 million gal./day) will still flow directly into the Buffalo River; but the waste water, by Jan. '71, will be sub jected to a specially designed threestep treatment. One problem in treating dye-plant wastes is the variation in the chemical composition of the wastes from each production line. To avoid the prohibi tive cost of separate treatment units for the various production lines, the wastes first go into an equalization res ervoir, where they are mixed for standardization and held for several days for primary settling. Second step is neutralization with lime. This precipitates the heavy-metal ions common to dyestuff making and lowers the sulfate-iron content in the waste stream.

Flocculants are added in the final settling tank to remove addi tional solids and also to remove the coolants in the mix. The clarified effluent--with its bio logical-oxygen demand lowered by 45%--will then be ready for biological treatment in the city's plant, which residents hope will be built by '71.

' Diving to dumpsite prospects are brighter tbfs week for an ik80-million pipelipe-'to sluice indus trial Vaslesjnter'the Atlantic Ocean some 80 miles off Atlantic City. N.J. (CW. July 19, p. 65). A group of scientists -- including Robert Erb, chemist at Franklin Insti tute (Philadelphia) and originator of the idea--last fortnight took a 28-hour trip in Grumman Aircraft's submersi ble, the Benjamin Franklin, descending to a 1,800-ft. depth to inspect the pro posed outfall site. (The vessel's ascent was delayed by passing Hurricane Gerda which brought 50 m.p.h. winds and 20 ft. waves.) Principal findings: ocean currents, sweeping slowly (V2 m.p.h.) down the Atlantic coastal slope, would dilute the wastes and carry them away from shore; and the pipeline could be laid easily. But representatives of the U.S. Bureau of Sport Fisheries and Wildlife, who were among the scientists on the deep dive, said the proposed dumping "would undoubtedly kill some marine life."
