Strainpress® Sludgecleaner SP

The Huber Technology STRAINPRESS is designed to effectively remove debris from sludge without breaking line pressure. Sludge is pumped into the Strainpress’ perforated tube and flows through the perforations into a casing while debris is retained within the tube. An internal screw pushes the retained screenings along the tube’s axis into a conical dewatering and compressing section that is provided with a smaller perforation compared to the screening section. This allows for screening the sludge while it is being pumped eliminating any need for having to pump a second time after screening.

A pneumatically operated cone, installed at the press zone’s discharge end, keeps the discharge opening closed and generates a back pressure. After a screenings plug has formed, preventing sludge flow towards the discharge end, and has been sufficiently pressurized by the screw’s movement, it pushes the cone back, and some dewatered and compressed screenings are discharged and drop into a container or bag. The screw’s flights keep the screen clean. No wash water is needed.
