Evac MBR supplier page

EVAC membrane bio-reactor (MBR) consists in merged intensive biological and ultra-filtration processes. The package wastewater treatment plant is composed of an equalizing anoxic tank, an aerated tank for biological process and a membrane submerged in the aerated tank. The effluent is produced by gravity flow or slight vacuum. The membrane is covered by a biofilm reducing the pore size down to ultra-filtration and providing further biological removal.

Evac MBR provides an extensive removal of contaminants allowing various reuse applications. Standard flow capacity ranges between 1.5 and 111 m³/day, above this value we provide a customized design. In addition, Evac MBR does not require to be placed underground or to have a post-treatment by soil infiltration.
