Guide for technologies that power the activated sludge process

Chlorine gas (Cl2) is a highly effective oxidant and a relatively economical option for disinfection. Since Charles F. Wallace and Martin F. Tiernan discovered the first chlorine gas feed system in 1913 the Wallace & Tiernan® brand is a synonym for safe and reliable disinfection of water. Chlorine can be safely transported, easily applied, measured, and controlled. See below for more frequently asked questions regarding Gas Feed disinfection.

Clarifiers are an important component of the wastewater treatment process. However, between corrosion, maintenance, and changes in flow, it can be difficult to keep a clarifier operating at peak performance. In addition, changes in effluent regulations may require upgrades to meet new, more stringent requirements. To learn more about clarifiers and their maintenance, Allen Lepak, Clarification Product Manager with Evoqua Water Technologies provides expert advice on how to identify some common issues with clarifiers, how to maximize performance, and how to decide whether you should upgrade or replace your existing unit.

Evoqua Water Technologies was chosen by Carolina Water Service, Inc. to design, manufacture, and install a new wastewater treatment system in Connestee Falls, N.C., replacing the old plant to improve efficiency and reduce environmental impact
