Ultrafiltration (UF) wastewater treatment membranes specially developed to improve ease of operation and maintenance in membrane bioreactors have been introduced by QUA®.

EnviQ membranes offer UF quality product water with a stronger and more rugged PVDF flat-sheet membrane. The membrane's unique features, such as reverse diffusion and specially designed air diffusers, maximize scrubbing efficiency resulting in reduced cleaning.

Pennsylvania-based QUA says that EnviQ significantly lowers the total installed cost of biological wastewater treatment and recycle systems compared with conventional activated sludge processes with tertiary filtration.

EnviQ is currently offered in three configurations: E-8C, 16C and 32C, each having surface area of 80, 160 and 320 m², respectively.
