Water Environment & Technology (WE&T) is the premier magazine for the water quality field. WE&T provides information on what professionals demand: cutting-edge technologies, innovative solutions, operations and maintenance, regulatory and legislative impacts, and professional development.
How MBRs grew more efficient
Evolving design philosophies have lowered the capital and operating costs of membrane bioreactors (MBRs) since the mid-1990s, increasing technology acceptance and application.
Installation and startup of advanced process controls
Advanced process controls do not come with a giant green button labeled “optimize.” Nor is installing and commissioning a system as simple as dropping some sensors around the plant and plugging all of the cords into the central control system. But the right methodology can provide successful approaches to time and project management, programming, and process troubleshooting.
New levels of instrumentation
Recent innovations in instrumentation are pushing the envelope toward greater system optimization and more sophisticated water quality monitoring. These advances have considerable potential to help utilities increase treatment efficiency, achieve greater nutrient reductions, and obtain a more thorough understanding of background watershed conditions.

What happened at WEFTEC 2011?
Not able to attend WEFTEC® in Los Angeles or too busy to get to everything? Find out what you missed. The December issue will contain a full wrap-up, including coverage of this year’s outstanding Opening General Session, an overview of where water leaders expect the industry to go in the next decade, an update from water policy and regulations sessions, as well as a report on what’s on utility managers’ minds.
In addition, the December issue will have full coverage of the 24th annual Operation Challenge competition. This pentathlon pits teams of four operators against the clock as they compete to prove their mettle. The five events are Collection Systems, Laboratory, Maintenance, Process Control, and Safety.
Congratulations to this year’s winners:
- Division 1 — Terminal Velocity from the Virginia Water Environment Association.
- Division 2 — Seacoast Sewer Snakes from the New England Water Environment Association.
Thicker solids automatically. In Green Bay, Wis., operators now can better monitor changing conditions in their gravity belt thickeners and adjust them more proactively. They also can identify thickener problems more quickly and make corrections before the problems become severe and time-consuming.
Small changes add up to big savings. Learn about a suite of changes in operational control and strategy that cost less than $500 to implement and have been proven capable of providing energy cost savings of 10% to 25% in many facilities.
Are you burning nonhazardous solid waste? Owners of wastewater solids incineration facilities face stricter air emissions limits and might have to upgrade or reconsider incineration as they feel the impact of the new MACT emission limits.
Changing paradigms. By understanding the barriers to technological improvements, water professionals can help transform wastewater treatment into resource recovery.
