The next generation of septage receiving

A fully automatic septage receiving unit incorporating a stainless steel perforated plate drum screen mod.

VSA with an integral washing, conveying and dewatering system. The system incorporates a dual drive

system which allows the screen basket and auger to run independently.

smaller inlet tank volume feeds solids directly into the drum screen and eliminates sedimentation in the tank.
