Sludge Treatment Dewatering & Thickening of Wastewater Sludge

Sludge in Wastewater Treatment Plants (WWTP) is an inevitable by-product of every wastewater treatment process. However, with FBAS (Fixed Bed Attached Sludge) technology, sludge production can be significantly minimized compared to conventional activated sludge systems or MBBR.

The sludge treatment process begins with thickening, enhanced by the addition of polymers. Thicker sludge consistency allows for more effective and optimal water separation. Following this, the sludge enters a critical stage: sludge dewatering. A range of advanced technologies can be applied at this stage, including belt press, screw press, and filter press.

Sludge dewatering is aimed at reducing the water content in the sludge, thereby economically decreasing its weight and volume to achieve more efficient disposal costs. The benefits go beyond waste volume reduction and transportation cost savings — it also results in a more stable sludge "cake" consistency and eliminates the risk of spills that could contaminate the environment.
