Ultra-Fine Filtration of Wastewater
The OKO-sf gravel filter is used when high demands are placed on the clear water quality regarding filterable substances. The ultrafine materials dispersed in the wastewater are retained by a multi-layer bed made of gravel and sand. Depending on the loading of the gravel filter, it is then automatically backwashed under pressure and/or time control for cleaning. Two gravel filters are usually required for an uninterrupted wastewater treatment. One gravel filter filters the wastewater, the second one is on standby and takes over when the other gravel filter is backwashed.
