Sludge water extn. - uses a conical container for sludge to pass through vertically under pressure, which is set according to water content

摘要

To extract water from sludge, the sludge is passed vertically through a conical container. The sleeve blankets are moved by a geared motor with infinitely variable control to set the throughput speed and the deg. of water extraction. The pressure is applied according to the water content, to give a lower pressure on a raised water content. A motor oscillates the container with its contents, to bring the water content to the sludge surface, and increase the water extraction rate. USE/ADVANTAGE - The sludge press unit is a low-cost system for sewage processing, which delivers a high content of dry material in the end product.
