Step 1
Greywater discharge from the house is sent to a collection well (underground pit). This collection well is designed to have an overflow to sewer to cater for high flow periods of the day.
Step 2
The NovaGrey system, on demand, activates a pump within the collection well that transfers the untreated greywater from the collection well and feeds it into the primary tank (known as MBR) of the NovaGrey.
Step 3
Once the greywater has been transferred to the MBR of the NovaGrey it undergoes a constant aeration process that provides the first level of biological treatment for the greywater.
Step 4
The MBR also houses the flat sheet membranes. The greywater is then transferred (via suction) through the 7 flat sheet 0.2 micron membranes housed within the MBR. This clean water is then pumped through a UV disinfection unit which provides the final stage of disinfection.
Step 5
The clean water once pumped through the UV disinfection unit is then stored in the internal effluent tank (IET).
Step 6
When the IET reaches an adequate volume a float switch activates the internal effluent pump (IEP) which then discharges the treated water through the household re-use storage tank.
