Retrofit riser pipe clarifiers with Tow-Bro® Circular Clarifiers

High performance sludge removal header improves sludge blanket control and settled sludge removal

Tow-Bro®​ Clarifiers provide high performance sludge removal header while reducing costs. If existing circular clarifiers are the riser pipe or organ pipe type, consisting of V-plows and individual pipes to transport sludge to a sludge box at the clarifier center, the Tow-Bro clarifier can provide significant improvements to sludge blanket control, the balanced uniformed removal of settled sludge, and the elimination of plugged pipes.
