Specifications
The basic EPRO unit is designed to
produce purified water at the
capacities indicated by the suffix in
the model number under the
following conditions: water temp
77ºF (25ºC) and a total dissolved
solid (TDS) of 500 ppm or less. For
example, the EPRO-1200 produces
1200 gallons per day (GPD) or
4,542 liters per day (LPD) of purified
water.
In addition to the standard models
the EPRO models are offered in the
following variations:
The "P" series EPRO systems are
reverse osmosis systems that
deliver purified water to a
pressurized storage tank. The
product water is typically stored in
the pressurized tank at 20-40 psi
and is distributed with tank
pressure.
The "A” series EPRO systems are
reverse osmosis systems that feed
permeate to a 65 gallon
atmospheric storage tank and
distribute the permeate with a
small dispensing pump.
The "XP" series EPRO systems are
modular systems with a reverse
osmosis unit, a 300-gallon
atmospheric storage tank, a liquid
level control, and a re-
pressurization system. A variety of
storage tanks and re-
pressurization systems are
available.
The "WM" series are reverse
osmosis systems suitable for wall-
mounted installation to save floor
space.
REJECTION AND RECOVERY
The amount of total dissolved solids
(TDS) rejected by the membrane is
expressed as a percentage. For
example, a 96% rejection rate means
that 96% of total dissolved solids do
not pass through the membrane. To
calculate the % rejection, use the
following formula:
NOTE: All TDS figures must be
expressed in the same units, usually
parts per million (ppm) or milligrams
per liter (mg/l).
The amount of purified water
recovered for use is expressed as a
percentage of the feed water, and is
called percent recovery. To calculate
% recovery, use the following
formula:
NOTE: All Flow Rates must be
expressed in the same units, usually
gallons per minute (gpm).
