Series WM - Wall
Mount RO Systems
Reverse Osmosis Systems
250 to
4,500 Gallons/Day
Economically Priced • Space Efficient • Superior Quality
Designed to produce low dissolved solids water from tap or well water, these
systems use high efficiency reverse osmosis membranes. The product water is
used in applications such as spot free rinse, water stores, whole house,
labs, ice makers, humidification, misting and a wide variety of other
applications.
The convenient and space efficient wall
mountable systems are substantially lower in cost than frame-mounted
systems, and are more cost-effective to ship.
WM Series systems are expandable to allow for
quick, easy and cost effective upgrades to systems in the field. Simply
purchase and install the appropriate expansion kit assembly to increase your
system capacity at any time down the road.
These reverse osmosis systems use the proven, reliable components and are
mounted on a sturdy powder-coated metal mounting backplate. There are numerous design
details learned from years of experience that are incorporated in our water
filtration systems. Our process and fluid design ensures an optimum membrane
life and minimizes the membrane fouling.

Notes: |
-
All dimensions and weights are
approximate.
-
Capacity Basis: 24 hrs/day
-
Systems rated at: 77°F (25°C) using 1000
ppm sodium chloride solution operating at approx. 175 psi pressure.
-
Minimum feed
pressure to RO System: 40-60 PSI. System capacity changes
significantly with water temperature.
-
Chlorine must be removed if present in
feed water prior to RO with a carbon filter.
-
Pretreatment for water hardness using
a softener or scale inhibitor should be added to avoid scaling the
membranes. Feed water turbidity: Less than 1 NTU;
Feed water silt density index (SDI): 3 maximum. If exceeded,
pretreatment with media filter recommended. All pretreatment
equipment and SDI test kits are available from Applied Membranes.
