Fine screen

The FSM compact screening / septage receiving station FRS-SPW provides high performance coupled with low operating costs. The compact screening / septage receiving station is a combination of the proven FSM filterscreen and the FSM screening washing press in one machine. This results in a compact machine with extremely high cleaning efficiency and through-put. The filter screen allows the passage of grit, which can be present in high quantities in septage, without malfunctioning. Functional principle: The waste water flows through perforated filter elements made of stainless steel, while contaminants are held back. Solid matter is picked up directly at the bottom of the channel, a base step being incorporated in the container. The filter elements form a continuous filter belt which is cleaned by a brush at the upper deflection point. The cleaning process is assisted by a series of jets working in proportion to the screenings load. Tines located on every 5th screening element prevent build-up of rolling matter in front of the screen and ensure that large matter is removed. The sheet steel side plates of the filter elements slide on delrin rails on the screen frame, thus forming a seal and preventing screenings from being washed past the screen at the sides. As a result of the half-round shape of the filter elements and the arrangement of the cleaning brush at the upper deflection point, the distance between the brush and the filter element remains constant. This constant distance ensures very effective cleaning combined with low wear of the brush.
