The Screw Press from Alfa Laval uses moderate rotational speed for low power consumption, providing a positive impact on operational costs. Its controls ensure consistent continuous operation with minimal need for supervision. The moderate rotational speed also results in a low noise level, ensuring a positive working environment, and low spare parts demand. Applications include dewatering of municipal wastewater plant sludge (primary, secondary, mixed or digested sludge), as well as industrial biosolids and biogas residues. It reduces sludge volume for lower transportation and disposal costs. 866/253-2528; www.alfalaval.us/wastewater.
