Multilayer Filter Type FNSIn waste water treatment plants multilayer filters are installed downstream as security filter. Filtration of suspended particles takes place in the upper layer consisting of hydroanthracite or silica sand. Backwashing is carried out by manual operation or automatically operated valves.
Due to its geometry, the corrosion resistant materials and the special filling, the multi-layer filter FNS has a remarkable filtration capacity. Pressure filter
The pressure filter consists of the vessel with valve system, manometer
and sampling-valve. The interior consists of a modern nozzle floor with
impact- and corrosion-resistant nozzles made of polystyrene. BackwashingManually operated with hand-valves or automatically controlled by pressure-difference. MaintenanceMaintenance is limited to regular backwashing which is released by simple adjusting of the operating valves. Examples of useMulti-layer filters are mainly used for clarifying and particle-filtration of liquids, f. ex.
