Evac EcoScreen - Mechanical Sewage Pre-Treatment Plant

The Evac EcoScreen is a mechanical sewage pre-treatment plant. It is a complete standalone screening unit, which can be installed in connection with a sewage treatment plant. A screening unit is recommended for the sewage pre-treatment phase in systems using a custom-designed Evac MBR (membrane bioreactor) to clean wastewater. The Evac EcoScreen unit mechanically separates most of the solid matter from the wastewater. Separating solids before the MBR is strongly recommended because solid matter may cause problems in the MBR unit. Separating solids also diminishes the organic load in the sewage by approximately 10–20%. If a screening unit is used, a macerator is not needed to chop the solid matter.
