After the cellulose washer, the sewage water flows through to the Salsnes Filter, which is a rotating belt filter. The filter works by rotating a filter cloth, creating an endless filter. The sewage water is fed into the machine on top of the filter cloth and then flows through it. The particles in the sewage water form a precoat on top of the filter cloth creating an even smaller pore size. The sievings from the Salsnes Filter are partially dewatered on the filter cloth, before being blown off by an airknife. A screw transports the sievings to the CellPress.
