Containment Methods for Odor Control Systems in Wastewater Plants

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.

Drinking Water Treatment Unit Certification

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.

The Importance of Filtration in Wastewater Reclamation

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.

Control System for Odorous Emissions From Rock Media Trickling Filters

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.

Membrane Specialists Gather for International Conference

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.
