Mechanical filters

Mechanical filters MF series

High efficiency mechanical filters are meant to separate the solids with dimensions over 1,5 mm, sediment from primary sedimentation and active sludge after secondary sedimentation from wastewater. The efficiency of suspended substance treatment is about 20-23%.

Use of mechanical filters guarantees stable operation of tertiary treatment unit and allow to avoid the sand separators and pre-treatment tanks. They are used at the WWTP with performance 1-1000 m3 per day.
