Abstract: In a vessel containing a filter bed and containing a mixed liquor containing suspended solids, a system disturbs/dislodges a sludge mat that settles on the filter bed. Thus, the system controls the sludge mat on the filter bed that otherwise may blind the filter bed and significantly reduce or stop process liquid flow into and through the filter bed. The system helps maintain effective vessel effluent flowrates with reduced requirements for filter bed backwashing or other filter bed maintenance. The system includes a sludge mat dislodging member that moves along the filter bed surface, preferably on but substantially not inside the filter bed, to disrupt/dislodge the sludge mat and/or prevent formation of the sludge mat. Preferably, the dislodging member is carried inside the vessel on a moving arm or arms that rotate in a plane parallel to the filter bed surface. The preferred sludge mat dislodging member(s) hang from the rotating arm(s) to slide along the top of the filter bed through the sludge mat.

Abstract: Disclosed is a method for connecting at least two thermoplastic elements. The elements are pressed together and welded elements whereby at least two welds are produced. This method may be used for friction welding of two overlapping sections of a thermoplastic strip. Also disclosed is a system for wrapping the strip around a package. The strip is passed around the package to form a loop whereby the sections are arranged at each end of the loop. The strip is tightened and secured by at least one clamping plate of the system. The strip is pressed against an abutment plate of the system pressing the overlapping sections together by a vibrating plate of the system. The overlapping sections are pressed against the abutment plate by the vibrating plate welding the overlapping sections by the vibrating plate whereby at least two welds are A produced one behind each other in longitudinal direction of the strip and separated from one another by an unwelded area of the strip.
