ABSTRACT:
A filtration process and apparatus for the removal of solids from liquids is provided having a filter bed vertically disposed in a chamber which has a solids-containing liquid passed horizontally therethrough. The filter bed is regenerated after becoming loaded with solids. During filtering the liquid is divided into at least two partial streams, and each partial stream is conducted through a respective filter bed arranged in a chamber, which is comprised of reticulated particles of polyurethane. After the particles have been completely loaded with the solids, the liquid feed to and the liquid discharge from the respective chamber are interrupted. The solids adhereing to the particles are then transferred by agitation and/or gas treatment into a liquid volume remaining in the chamber, and the liquid volume is discharged together with the solids. The process is especially adaptable to be utilized in wastewater treatment, or for the removal of solids from scrubbing media.
