Innovative Turnkey Gray Water Systems
Manufacturers and Systems
- Ecovie Water Management (Aqualoop): Offers commercial gray water recycling systems that are NSF 350C certified, a standard for water reuse systems. Their process involves pre-filtration to remove large debris, biological treatment to break down organic matter, and ultra-filtration with a 0.02-micron membrane to exclude bacteria and viruses. (LINK)
- Water Wise Group (Aqua2use Pro): Provides automated, small-commercial gray water systems for applications like schools and large homes. The system uses a progressive filtration process before diverting the water for reuse, such as in irrigation systems. (LINK)
- Rainwater Management Solutions (GRAYWORKS): This modular system is designed for a range of commercial applications. It includes biological treatment, filtration, and disinfection in a single unit to handle variable flow and concentration. (LINK)
- Wahaso: Offers scalable, commercial-grade greywater harvesting systems that can process thousands of gallons per day. The standardized equipment includes filtration and sanitation, with customizable options for tanks, pressurization, and controls. (LINK)
- Highland Tank (HighDRO-Clear GRS): These systems are engineered for site-specific applications but follow a standard design. They feature a multi-stage process, including biological, media, and carbon filtration, followed by UV and chemical disinfection to treat greywater for reuse in applications like toilet flushing and irrigation. (LINK)
- Flotender: Sells multi-zone gray water processor systems, which come in pre-sized units with pumps and filtration to automatically distribute filtered and pressurized gray water to subsurface drip irrigation. (LINK)
