Sand filtration

Sand filtrationAquaBiofilter™ is a continuously moving bed sand filtration process, which provides uninterrupted operation and constant sand cleaning and redistribution via a central airlift mechanism. The system can be designed to provide tertiary treatment including biological nitrification, biological denitrification, suspended solids removal, BOD removal, and phosphorous removal.

Sand-Cycle represents the latest development of this technology, where the sand circulation rate and distribution is constantly monitored by microchips embedded in the sand, enabling operators to identify potential maintenance requirements in advance of process issues.
