Containment and processing of odors, as well as emissions of VOCs (volatile organic compounds) and HAPs (hazardous air pollutants), whether regulatory-driven or good neighbor-/community-driven, are forcing municipal and industrial wastewater facilities to evaluate and re-formulate their processes so they can achieve the mandated or desired atmospheric emission levels.
Wastewater treatment facilities are being force to re-evaluate procedures for containing and processing odors and emissions of VOCs and HAPs as a result of new regulations
You are familiar with the water quality problems in your area, but finding a line of equipment that you can have faith in, that is reliable and consistently performs as claimed, may not be as easy as it first appearsThe water treatment business is growing rapidly and all signs point to a continued steady growth. As new technologies emerge, the already complicated business of selling water treatment equipment becomes more complex.
By adding filtration and disinfection to their wastewater treatment plantthe East Chicago Sanitary District has found some strange and welcome inhabitants in the disinfection contact chamber.
Pilot tests have demonstrated that EHRSF can meet Surface Water Treatment Rule requirements.
No longer are turbidimeters the sole measurement method for water purity levels.
Faced with upgrading aging facilities, a Florida water utility decided to incorporate reverse osmosis.
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.
A Philadelphia water company improved the performance of and reduced the operating costs of its filtration system with modernized high-rate gravity filters.
The latest on membrane technology for water treatment.Membrane system technology has been developed to a point where one or more of its forms can be applied to extract most of the contaminants of concern found in many raw water sources. Recognizing the importance of the latest findings to the drinking water supply community, the International Water Supply Association recently conducted a conference on the subject in Paris, France.
