Envirex® High Performance Clarifiers


For over 50 years, Evoqua’s Envirex product family has provided custom designed, circular clarifiers for municipal and industrial water and wastewater treatment applications. The quality of the engineered designs, the superior fabrication of the finished products and the consistency of experienced, after-installation services have contributed to the Envirex brand reputation as a leading supplier of proven clarifier equipment.

Clarifiers are designed to remove settled solids from the bottom of the clarifier tank as quickly as possible to improve the efficiency of treatment processes. Considerations involving inlet energy dissipation, solids settling characteristics, liquid flow patterns and effluent collection are all part of the design parameter. Our engineers have furnished proven designs for virtually every type of clarifier application.
