| Abstract |
The Kehr modification of the activated sludge process (KASP) uses a completely mixed aeration tank with no intentional solids wasting. After the aeration tank stabilized at between 4000 and 12,000 mg/l of MLSS, a 40 day investigation using municipal and cannery wastes of strengths from 200 to 2000 mg/l BOD5 was conducted. 90% BOD5 and 80% TOC reductions were achieved, but little or no reduction was detected in nitrates and phosphates and the effluent was colored and turbid. Periods of little or no loading for as long as 48 hours caused no decrease in treatment efficiency when flow was resumed. From the above information, KASP was recognized as being well suited to industrial waste pre-treatment prior to discharge to a municipal treatment plant. The ability to handle intermittent flows provide 90% BOD5 removal, and provide aerobic digestion of solids in the aeration tank is essential for pre-treatment devices and all are possessed by KASP. Exclusive of primarytreatment, treatment of 10 mgd of a 250 mg/l BOD5 waste would cost 7 cents/1000 gallons using gravity settling. (Author) |
