Sewage sludge thickening
WebSewage Sludge Treatment Process 1. Sludge Thickening This is the first step whereby the sewage sludge is thickened in a tank called a gravity thickener. The process reduces the sludge’s overall volume and also enables its easier handling. WebThe THK Series Sewage Sludge Thickener improves upon existing technologies using fundamental principles of a 1) Centrifuge - 3,000 Gs, 2) Rotary Drum Thickener - fully enclosed and small footprint, 3) Dissolved Air Flotation (DAFT) - air injection.
