biological sludge thickening system including a preliminary concentration stage – Drainis™ Turbo

biological sludge thickening system including a preliminary concentration stage – Drainis™ Turbo
The Drainis™ Turbo is composed of a pre-thickener followed by a mechanical thickener (gravity belt thickener, drum thickener, centrifuge).

Utilizing fast gravity decantation, it also enables the stable concentration necessary for an optimized feed into a mechanical equipment thickening.

DrainisTM Turbo is fully adapted to urban and industrial wastewater sludge.
