- Indoor Grey Water Systems



The Aquagrey Indoor Grey Water system consists of three components: The aerobic treatment (AT) and Membrane Bio Reactor (MBR) consists of several tanks to collect the grey water from showers, baths and washbasins and for biological preparation by means of venting and a preinstalled filter unit (ultra filtration). This filters viruses, bacteria and suspended matter out of the grey water. The purified water is transported into the clear water tank without the use of a further pump by means of patented airlift technology.

The purified grey water is stored in the clear water tank (CWT) and could be conveyed by a submerged force pump to the points of use. If additional water is required, the clear water tank could topped up with mains water in compliance with EN1717.

Technical components: Aeration pump, vacuum unit and system controller are pre-mounted on a console, which could be installed easily inside of the building.
