The term greywater has many uses and varies according to industry, and, as such so does grey water recycling. Broadly speaking, greywater refers to wastewater created from handwash basins, showers and baths, and can be reused for specific things such as irrigation or WC flushing. On an industrial scale, greywater can be output from a factory process, discharge from a cleaning process or wastewater from a specific production process. Greywater differs from blackwater, which has been exposed to sewage.

Greywater Recycling Can Reduce Your Company's Water Footprint
Because greywater typically contains lower levels of contaminants, grey water recycling is often significantly easier to accomplish than blackwater recycling. If collected correctly, it can be recycled directly within a process; this saves considerable water from going to drain and makes a substantial difference to costs and energy consumption. With increasing awareness of'blue risks' and rising price of water supply and drain, it will become increasingly important to appreciate the importance of grey water recycling.
Grey water recycling can also be applied to the process of reusing water in agricultural process or in situations where rainwater is relatively clean - in this case water purification may not be required. In setups like this, a near-continuous supply of grey water is advised otherwise bacteria can build up affecting the water that is being reused. Generally, grey water recycling systems are coupled to water purification apparatus when the water is required to be potable, or when used for other industrial applications - cleaning, for example.
We believe that greywater recycling not only represents an environmentally responsible process but will also offer significant long term savings in water supply and drainage costs.
