As the discharge requirements for treated secondary effluent become more restrictive, effluent filtration is becoming a more integral part of secondary treatment. Because a high quality effluent is produced after filtration, the potential for reusing treated effluent is being examined by a number of municipalities, especially those in the water-short areas of the southwestern United States. A new concept of filtration in reuse applications and an innovative filter technology is being used to help alleviate some of these problems.
Effluent filtration is an integral part of secondary treatment as discharge requirements become more restrictive
The South Monmouth Regional Sewerage Authority's 9-mgd wastewater plant had been identified as a source of odors that bothered neighbors from time to time. As a result of work done on the plant's two trickling filters, which were shown to be the culprits generating the unpleasant odors, emissions from the filters have been significantly reduced and complaints of odors have been virtually eliminated.
