Abstract Olin Corp. and the consulting engineering firm of Malcolm Pirnie Inc. designed a combined waste treatment system (with separate pretreatment) for two types of wastewater, one with, and the other without, propylene oxide, which are generated at Olin's DOE Run, Ky., chemical plant. The activated sludge procedure treats 6.1 million gal/day of water, which is returned to the Ohio River after treatment. Wastewater characteristics include moderately high-strength organics (BOD/sub 5/ of 700 mg/l.), very high temperatures (170-180/sup 0/F), high pH levels (11-12), and high calcium chloride (3.25%). Carbon dioxide produced as a by-product at the plant is used to neutralize the basicity and remove calcium chloride as calcium carbonate prior to the activated sludge treatment.
