AQUALOOP Greywater Systems

AQUALOOP produces water that is bacteria and virus free with input water from household gray water, rainwater, surface water, groundwater, runoff water from wastewater treatment plants, or industrial wastewater! Recycle greywater from showers and laundry easily and economically with new water treatment technology. Use AQUALOOP greywater to irrigate, flush toilets, cooling tower make up, and run laundry, in a wide range of buildings:

AQUALOOP is certified at the commercial scale for NSF 350.  This means that greywater treated with the Aqualoop process is suitable for indoor use for applications like toilet flushing and laundry for all your needs from single family homes to large commercial applications.  It also means that Aqualoop treated water can be stored for extended periods and used for spray irrigation.  Unlike other processes which require greywater to be used within 24 hours and then only for subsurface drip irrigation, Aqualoop water is free to be used a much wider variety of applications.

How Does AQUALOOP Work? AQUALOOP Greywater Treatment consists of 3 stages:

Pre-Filtration – For single household systems, a PURAIN filter screen removes contaminants such as hair and lint before water goes to the reactor tank. Click Here for more information.
Membrane Bioreactor (MBR) – A bacteria support media with aeration controlled by the membrane station and blower to achieve optimal biological treatment. Click Here to find out more about the support media and Click Here for more on the membrane station.
Membrane Filtration-0.02 micron ultra-filtration removes contaminants with 6 log reduction of bacteria (99.9999%) and almost 3 log (99.7%) virus removal.  Click Here for details.

UV disinfection can be added if your situation or local permitting require it. The advantages of AQUALOOP over other gray water treatment processes are many:

  • No storage time restrictions as exist with simple greywater systems
  • The system can be scaled to any capacity, from 50 to over 10,000 gallons per day
  • The system is low maintenance as proven by the NSF 350 certification
  • Only certified system with NSF 350 (C) for commercial scale greywater systems.

For larger applications such as hotel laundry facilities, the potential for high ROI and water savings make AQUALOOP an excellent business decision. Here are some resources about AQUALOOP: Brochure
