GT600 Greywater treatment system

The Oasis Domestic Greywater Treatment System (GT600) is capable of generating a saving of almost 400 L of drinking water a day for the average four-person household. It takes the greywater generated by baths, showers, laundry and hand basins and treats it to a high quality suitable for garden irrigation, toilet flushing, clothes washing and car washing.

The sleek, compact, above-ground design of the system requires no excavation. Treated greywater is discharged at pH 7.0, a neutral level which doesn't effect soil fertility. The treatment process is chemical free so no chlorine or other chemicals, which contribute to the depletion of the ozone layer, are added to the environment. The recycled water is disinfected to make it safe for human contact and allow its use for irrigation of fruit and vegetable gardens.

An additional benefit of the system is that it decreases the harmful effects of high levels of phosphorus to 3 mg/L.

The greywater is treated in a three-step process. The water is first screened to remove lint, hair and other particles; it then passes through media where contaminants are removed through absorption, biological process and filtration; and it is finally disinfected. The system has a collection water tank, a processor and a treated water tank where the recycled water is stored prior to re-use.
