Reclamation Systems
Water Control RW-OZ Series Water Reclamation Systems provide an innovative option for
drastically reducing building water and sewer usage, gaining multiple points towards LEED®
certification, and minimizing the negative environmental impact of new and existing commercial
facilities. These systems harvest and store rainwater, graywater, condensate, groundwater and
backwash water (as well as water from other select sources) – and then reuse it to provide clean,
nearly potable quality water to irrigation systems, toilets, urinals, cooling towers, washdown tanks,
and other non-potable applications. With over 40 years of experience in commercial water filtration
and conditioning, Water Control is a name you can count on for innovative, high quality solutions to
your "green" system challenges.

RW-OZ Series Details:
RW-OZ SERIES UNITS Turnkey water reuse systems, which arrive pre-plumbed
and pre-wired for easy installation and operation. A powerful ozone system aids
in removing contaminants as well as disinfecting and deodorizing. The onboard
purification process provides filtered, sanitized, odor-free water on-demand. No post
holding tank or sump pump is required on most applications. The system’s small
footprint takes only minimal space in the mechanical room.
THE OZONE RECIRCULATION SYSTEM Operated independently from the
filtration pump system and is controlled by an ORP feedback system to ensure
constant disinfection levels of minimum 0.05 mg/l. (approx.). The powerful ozone
re-circulation system serves to disinfect any contaminants, so that they may be easily
captured by the micro-pore filtration system. Ozone kills microbes, enzymes, and
bacteria so that there will be no build-up of organic growth, nor will there be a build-up
of odor-forming bacteria. Within minutes, ozone (O3) reverts back to oxygen (O2). This
results in sanitized, odor-free water, with no harmful byproducts or contaminants.
THE PRIMARY FILTRATION SYSTEM Pump (and an associated filtration
array) is designed for maximum water quality. The system receives ozone-treated,
reclaimed water from the holding tank (cistern) and processes this water to remove
all particulate matter of greater than twenty-five (25) microns. In addition, the filtration
system is self-cleaning (backwashing), requiring little or no maintenance. The system
provides water “on demand” so no post-holding tanks are required. The “AutoBypass”
feature automatically switches to fresh water when cistern water levels are low, ozone
concentrations are low, or the filtration system is backwashing.
INSTALLATION: After the cistern tank is in place, a plumber can typically install the
system in two days. An electrician simply connects required power to the unit. Once
installed, a simple, one-time factory startup is all it takes to get the system into service.
MAINTENANCE Primarily limited to periodic inspection and cleaning of simple
screens and pump baskets, which can be accomplished in a few minutes about once
a month.
QUALITY FEATURES Includes a powder-coated aluminum frame, stainless steel
self-cleaning filter housings, schedule 80 PVC & solid brass plumbing, heavy-duty
pumps, stainless steel hardware, and much more.
