Abstract |
Federal Water Pollution Control Administration - City of Cleveland demonstration of Raw Waste Flocculation Process conducted at Cleveland Easterly showed significant improvements in plant operations, such as (1) increase in SS and BOD removals in primary treatment, (2) more efficient operation of the secondary treatment process, (3) increase in sludge pumpability in a 13 mile force main, and (4) cost savings approaching cost of polymer treatment. A detailed cost analysis showed that significant capital costs savings could result if this process were practiced. A completely automated polymer dispersal and addition system was developed. |
