Getting To Know Your System
The BWS350 Advanced Membrane Separation System is designed specically for users that desire the ability to customize
the TDS (Total Dissolved Solids) level or “Mineral Content” of the treated water. The BWS350 utilizes a precision multi-turn
Blending Valve to accomplish this with great accuracy. This system design maximizes the ability to accurately blend a calcu-
lated percentage of the ltered water with the product water exiting the AMS-QT Membrane, providing an Optimized Water to
your equipment with the characteristics that you desire.

BWS350 System Installation, Operation & Maintenance 4
Installation Requirements
This section and the next provide the water, electrical
and space requirements for the BWS350. Pay
special attention to the feed-water chemistry
requirements. Operating a system on water supplies
outside of these parameters may lead to premature
membrane failure. This product is for commercial
use only and must be installed and maintained in
accordance with manufacturer’s guidelines and local
regulatory plumbing and electrical codes.
Operating parameters
Typical Membrane TDS* rejection:
97+%
Feed Temperature: 40 - 100° F (4 - 38° C)
Feed pressure: 50 - 80 psi
(3.4 - 5.9 bar) at 1 gpm
Production** (at 77°F, 60 psi)
350 gals/day,
14.6 gals/hr, 0.24 gpm
Recovery: up to 33%.
IMPORTANT NOTE: The nominal production rate
is strictly dependent on feed water temperature
and pressure. Reduced temperature or pressure
will reduce production. For example: Operating
pressure of 30 psi will cut production by 50%. 48˚F
feedwater will cut production by 50%.
Location
The system should be installed indoors, in the
proximity of the equipment (within 25 feet) and
protected from the elements. Do not let the processor
or storage tank freeze or be exposed to rain or direct
sunlight.
Post-treatment
Treated water stored in a tank may absorb organic
compounds from the tank, which can affect water
taste and odor. If product water is for consumption, an
optional post-treatment lter, such as an OptiPure
FX or QT carbon lter, should be installed after the
tank. If used, it is best installed as close to the point of
use as possible. Other specialized post-treatment is
also available.
Feed water connection
An adequate ow and pressure of water to the unit is
essential for successful operation. Provide a dedicated
1/2” water line to the vicinity of the installation. Install
a full-ow ball valve and pressure gauge with 1/2”
female pipe thread (user supplied) for connection to
installation hardware provided with the system. A 1/2”
*TDS (total dissolved solids) create conductivity in water and are
expressed in ppm or mg/l (parts per million or milligram per liter).
System Reject % depends on blended water setting.
**Nominal production @ 77°F (25°C) @ 500 ppm based on a 24
hr day. Actual production will vary based on variations in water
temperature, pressure, and TDS.
male pipe thread x 3/8” push-to-connect adapter is
included in the installation kit.
Drain
A drain should be located within 5 feet of the location
of the unit. Drain must allow a minimum ow of 2
gallons per minute. Compliance with most local
plumbing codes requires installation of an approved air
gap in the drain line. The drain connection should be
accessible for system set-up and service.
Electrical requirements
A power source with two outlets should be located
within 5 feet of the location of the unit.

RP Pump
120V, 6 Mz, 6 Watts or 230V, 50Hz 6 Watts

Feed-water chemistry
Feed TDS Up to 1200 ppm
Feed pH 6 - 10
Hardness 28 grains or less
Free chlorine <2 mg/l
Iron (Fe) 0.1 mg/l max.
Turbidity <0.05 NTU
Manganese 0.05 mg/l max.
Hydrogen sulde 0.0 mg/l
A water analysis must be conducted before installing
the system, or the information requested above can
be obtained from your local water utility. If your water
analysis shows that any of these parameters are not
within range, additional pretreatment and/or higher
frequency of maintenance may be required. Contact
your OptiPure distributor for assistance. The presence
of silica or occulants such as alum or cationic
polymers in the feedwater may cause membrane
fouling and may require special chemical pretreatment
or periodic membrane cleaning. Please note that
membrane failure due to fouling is not covered by the
warranty.
Storage Tank
The tank must be located within 10 feet of the water
processor unit. The oor beneath the storage tank
should be smooth, clean and free of sharp objects that
could puncture the bottom of the tank. Note: The tank
is atmospheric, with a sub-micron, hydrophobic air
breather lter.
Optimized Water Lines to Equipment
Tubing, piping and associated ttings connecting
Optimized water lines to equipment shoud be food
grade material that meets NSF Std 51 or 61 with a
minimum pressure rating of 75 PSI. Optimized water
may react with most metal piping imparting a bad
taste. Plastic pipe or reinforced opaque beverage
tubing are acceptable choices for Optimized water
distribution. The larger inside diameter tubing or hose,
the better to minimize pressure drop.

IMPORTANT - ALLOW A MINIMUM OF 24” IN FRONT OF THE PROCESSOR FOR MAINTENANCE AND SERVICE. DO NOT MOUNT
SYSTEM ABOVE THE CEILING OR IN A LOCATION THAT IS NOT EASILY ACCESSIBLE. WHEN THE 50 GAL. TANK ASSEMBLY IS
FULL OF OPTIMIZED WATER IT WILL WEIGH 450 LBS (THE 16 GAL. TANK, 140 LBS). ALWAYS LOCATE THE STORAGE TANK
WHERE IT CAN BE ACCESSED DURING SERVICE.
