Aqualoop Greywater System Updates

As many of you know, Aqualoop is a water
treatment technology used for treatment of a variety of water sources for use
on-site.  The most common application is
for greywater recycling.  Aqualoop is
certified for this purpose with its NSF 350 listing for commercial scale
treatment of domestic bath/shower and laundry water for non-potable uses.  Aqualoop is also used for rainwater and
stormwater treatment for on-site use.  In
the case of rainwater, Aqualoop treated water reaches drinking water
quality.  Other uses include treating
water from blackwater primary treatment and water from surface water and
groundwater sources such as streams, lakes, and wells. See our portfolio for some
examples of projects

Below are some recent developments
regarding Aqualoop for greywater recycling including our updated NSF listing,
new Aqualoop Model numbers, and specifications to reflect these updates!

Listing Update:

The Aqualoop NSF 350 (C) listing has been
updated to be more straightforward and understandable to property owners,
regulators, and engineers.   Some new models, the GW3600L and GW5400L, were
added to show larger daily average capacities. NSF has confirmed that there is
no prohibition against using multiple units to attain higher flows.  For example, two GW5400L units can be used in
parallel to achieve an average daily rated capacity in increments of 1427 GPD to
reach larger capacity.  Ecovie and Intewa
review these designs to assure they meet all design scale up criteria.  A summary of these criteria is shown on the
updated specification sheet (CUT sheet) for the new models.  In addition, an updated user manual for
Aqualoop is being developed to cover the new model designation. 

New Models

Ecovie is introducing a new model numbering
which matches the Intewa worldwide Aqualoop model numbers and the NSF 350
listing.  This covers products meant for
single family residences through large commercial scale installations.  The NSF 350 listing had previously shown
model from GW300L through GW1800L. 
Models GW3600L and GW5400L have been added which scale to up to 1427 GPD
per unit.  In addition, designers can use
multiple NSF 350 listed units to scale to larger systems.

Please see the updated specification sheet
covering these clarifications.  Note that
the specification indicates how to size each Aqualoop system; bioreactor
sizing, blower sizing, MBR growth media, etc. 
Each Aqualoop model includes the following:

  • Membrane Cartridges
  • Membrane Station
  • Controller
  • Blower
  • Growth media
