Abstract: A filtering system that includes a filter housing that includes a fluid inlet and a fluid outlet, a substantially cylindrical filter located within the filter housing, and a backwash body movably mounted within the filter housing for backwashing the substantially cylindrical filter. The backwash body includes at least one nozzle adapted to move towards the substantially cylindrical filter during a backwash operation. A method for cleaning a filtering system, the method includes: (i) determining to perform a backwash operation; (ii) helically moving a backwash body that is movably mounted within a filter housing such as to scan an inner face of a substantially cylindrical filter, during the backwash operation; and (iii) moving at least one nozzle towards the inner face of the substantially cylindrical filter, during the backwash operation.

Abstract: A hydrocyclone separator comprising a truncated cone-shaped vessel having a tangential fluid stream inlet, a fluid stream outlet, a solid particle collector and a conical insert removably mounted between the truncated cone-shaped vessel and the solid particle collector, said conical insert comprising an erosion resistant material.
