How does the greywater system work?
The greywater system installed at Sharland Oasis is a NewWater greywater system. It is a BIOLOGICAL PEAT CARTRIDGE AND SAC (PCS) SYSTEM. The heart of the treatment process (patent application) is using a peat as a biological fixed growth reactor (FGR) media to achieve a 20:30 effluent with E. Coli of less than 30 orgs/100 ml. Trials are being conducted on the process that may enable an even higher quality effluent to be achieved with wider reuse potential. The PCS system comprises a Collection Cell with a minimum capacity of 700 l and an automatic overflow to sewer or approved discharge such as leachate trenches. The greywater is then pump via a hair and lint trap to a Treatment Cell where biological treatment together with chemical and physical removal processes take place. The Treatment Cell has a minimum of two replaceable peat cartridges each capable of treating up to 213 l/d. The minimum treatment capacity is 426 l/d but will typically be 639 l/d with a standard three Peat Cartrid
