The greywater from showers, bathtubs, and sinks is pre-filtered by a PR150-S PURAIN Filter, before being sent to the 5,000 L plastic tank (bioreactor). This is where the biological treatment is found. The skimmer overflow on the PURAIN removes any floating debris. With 2 AQUALOOP Membrane Stations in the bioreactor, the water will be ultrafiltered and supplied to a treated water storage tank (5,000 L). The greywater treatment for this project is achieved as an indoor tank system.
Through a supply pump in the treated water storage, the treated clear water is pumped to a holding tank in a PROFI pump and control centre. From there the double-pump system supplies the toilets and outdoor taps.
