Klampress belt filter press technology from Ashbrook Simon-Hartley is adaptable to the full range of sludge types. Klampress technology incorporates multi-zone dewatering, including a conditioning zone; gravity dewatering zone; an adjustable wedge-zone (also adjustable during operation); radial dewatering zone and full-pressure zone. Depending on specific sludge characteristics, the Klampress is configured with expanded pressure zones, with an integral gravity belt thickener, as a high solids unit or with a combination of these options to achieve specific results.
