Water Pollution Control Plant Upgraded to Meet EPA Regs

Serial Information: Civil Engineering—ASCE, 1982, Vol. 52, Issue 6, Pg. 56-57


Document Type: Feature article

Abstract:

An Outstanding Civil Engineering Achievement Award Nominee, Philadelphia's Southwest Water Pollution Control Plant, has a $300 million addition which nearly doubled plant capacity to 210 mgd. Begun in 1975, the plant can remove 90% of the pollutants from raw sewage and industrial waste. The plant's control center is completely computerized and is one of the first to seriously incorporate computers into the plant operation. Plant operators were consulted during the design and their experiences were incorporated into the design. The plant has its own cryogenic fractional distillation oxygen unit which produces oxygen for the treatment process. Sludge gas is collected and utilized for sludge heating, space heating, scum incineration and grit incineration. A flow chart of the major processes of the plant is included.
