A filter element for use in a filter disc, wherein a plurality of filter elements are arranged on a rotor shaft in a manner allowing liquid communication between the inside of the filter elements and the inside of the rotor shaft. The filter element has at least one passage in an edge structure for liquid communication between the inside of adjacent filter elements when the filter elements are assembled forming a filter disc. The passage has different passage area along the edge structure.

A system and apparatus configured to facilitate on-site treatment of wastewater from a residence is described. The system is configured to immediately treat wastewater as it is generated, on an as-needed basis, and works to remove undissolved down solids and reduce dissolved materials concentrations to a uniform level prior to transmission of the wastewater to municipal waste water treatment facilities and/or any non-drinking application. The system employs a two-stage treatment apparatus where the first stage is configured to pre-grind and decompose undissolved solids of the wastewater and the second to reduce dissolved materials concentrations. The first stage uses turbidity meters, and the second stage uses pH, BOD and conductivity to ensure a uniform output from each stage. A fast decomposer has rotating filters which operational modes ensure that the filters do not become clogged with solids in a cake form simultaneously.

A vacuum and/or pressure filtration device includes a filter drum defining a drum axis and it is supported rotatably around the drum axis. The filter drum includes an outer jacket, by which a plurality of filter cells are formed, which extend along the drum axis, which are arranged adjacent to each other all around the drum axis, and which are equipped on their outer side with a filter medium; and an inner jacket, which is arranged adjacent to the outer jacket, which has an inner jacket outer surface, which limits the filter cells radially inside such that by the inner jacket outer surface a plurality of draining surfaces are formed, on which the liquid passing through the respective filter medium during filtration of the suspension can drain as a filtrate. The filtration device filters a suspension having solid and liquid components.
