The current global water crisis has generated a demand and market for systems that facilitate the reuse of water.Greywater is domestic wastewater from showers, sinks, and laundry facilities. It is essentially, all domesticwastewater with the exception of wastewater containing sewage. Greywater is a suitable source of water forreuse because of its consistent production and the onsite need for recycled water. In Canada, there are noregulations for effluent water quality of greywater . Therefore, most of the current facilities rely solely onprimary treatment including mechanical sieving and disinfection. These systems can promote health risks,operational and aesthetic issues due to their inability to eliminate acceptable level of suspended solids,dissolved organics, and microorganisms. Only recently National Sanitation Foundation (NSF) in the USA, andCanadian Standards Association (CSA) in Canada developed NSF350-1 (2011) and CSA B128.3 (2012), toaddress water quality criteria for reused greywater. Both of these standards have stringent requirements for thereduction of chemical and microbiological contaminants . Currently, there is no greywater system certified byCSA B128.3, and the only NSF350-certified system is Biobarrier? a product of Bio Microbics Co, USA.Therefore, there is a huge gap identified in Canada's market for a physical (non-chemical and non-biological)treatment stage capable of meeting stringent water qualities identified in NSF350-1 and CSA-B128.3.
