In water resource recovery systems, foaming is a pervasive problem that can occur in aeration tanks, secondary clarifiers, and anaerobic digesters. The consequences of foaming range from inconvenient, such as the need for additional housekeeping or dealing with unpleasant odor—to disruptive, like elevated total suspended solids (TSS) and biochemical oxygen demand (BOD) in effluent or decline of solids inventory up to 20%—to downright dangerous, including wind disbursement of pathogens and even fires caused by foam entry into oxygen compressors. Furthermore, these types of operational issues significantly impact costs, making it crucial to prevent or otherwise correct foaming as efficiently as possible.

Since the Clean Water Act and formation of the EPA in the 1970s, water resource recovery entities in the U.S. have been legally required to continually improve the quality of their effluent. Spurred by rising population and production, however, wastewater quantity has actually increased over the same timeframe. The combination of these 2 factors has necessitated more efficient removal of pollutants to produce discharge within environmental regulatory limits, including with regard to BOD and COD.

To better reflect the commitment of EnviroZyme® and our customers to long-term environmental sustainability, as well as use of our microbial solutions to produce clean water, our Wastewater Treatment product line has been enlarged and renamed Water and Environmental Technologies (W.E.T.)!

Permit effluent limits for ammonia are becoming more stringent, making its removal one of the most important and most difficult processes to maintain in water resource recovery.

We are excited to announce that EnviroZyme® is now offering a new service: microbiological testing of wastewater!
