Grey Water System :
The use of grey-water recycling systems in new commercial buildings offers a method of saving water and reducing total sewage volumes. By definition greywater is generally waste water from showers, baths, basins, and washing machines. Greywater treatment is easier than municipal wastewater treatment, generating a large interest in its reuse and recycling.
The main advantage of keeping greywater separate from toilet wastewater is that the pathogen load is greatly reduced, and the greywater is therefore easier to treat and reuse.
Greywater from kitchen sinks contains fats, oils and grease, and high loads of organic matter. It should undergo preliminary treatment to remove these substances before discharge into a greywater tank.
For most households greywater contains soap, shampoo, toothpaste, shaving cream, laundry detergents, hair, lint, body oils, dirt, grease, fats, chemicals (from soaps, shampoos, cosmetics) and urine. The most significant pollutant of greywater is laundry detergent, particularly those high in sodium and phosphorus.
