Pre-dewatering Belts


Pre-dewatering belts are the equipment which reduce sludge volume in several types of treatment plants. They can be used either before the belt press units, or as a separate sludge thickener. Especially in plants which treat nitrogen and phosphorus, they may be preferred as a mechanical thickener as the sludge stand-by time is shorter. Pre-dewatering belts provided by Sismat Uluslararası are especially designed for having continuous operation, low polymer and energy consumption compared with the other mechanical thickening equipment, long lifetime provided and low maintenance requirement. They are compact equipment which do not require extra space when used on top of the belt press units. Effective distribution of sludge is provided with the pillow blocks to have maximum efficiency. The number and spacing of the pillow blocks are determined depending on sludge characteristics. Drums can be added to increase belt length depending on capacity requirements. Sismat Uluslararası Pre-dewatering Belts are mainly made up of drums, belt, pillow blocks and drive unit.
