Secondary clarifiers are usually designed with a centre hopper and a bed plate inclined to the tank centre. The base plate should have neither unevenness nor roughness so that the sludge residue can be picked up by the scraper. Wall crowns of secondary clarifiers have to withstand exceptional loads. Frost, de-icing chemical and the pressure of the scraper wheels also require the best construction and processing quality. The special versatility of our system formwork is offered for creating your sewage treatment tank.
