| Explanation of Standard Features:
|
Liquid-filled system pressure gauge: This gauge is filled with glycerin. The "liquid" prevents gauge needle vibration.
Inlet/Outlet pre-filter gauges: These gauges monitor the pressure BEFORE and AFTER the system pre-filters. This allows you to know when to change out the pre-filters. A pressure differential of about 15 psi between the two gauges indicates the filters should be changed. Example: Pre-filter IN pressure is 50 psi and Pre-filter OUT psi is 35. This is a differential pressure of 15 psi.
Stainless steel fixed waste/recycle flow controls: The fixed flow control devices are stainless steel flat plates with a small hole drilled in the center. This flow control feature regulates waste water and recycle flows. The COMPACT model RO system is pre-set to obtain a 33% feed flow recovery. This means that for every gallon of product water produced, 2 gallons flow to drain. Fixed flow control makes certain the recovery rate is tamper proof.
Storage tank pressure switch: All COMPACT models come standard with a bladder (pressurized) tank pressure switch. This means
that the COMPACT RO system is set up for product water to be stored in a pressurized storage
tank only. If you are using an open (atmospheric) tank, you will require the optional float
switch. The pressure settings on the tank pressure switch will make the COMPACT RO system turn
off at 50psi and turn on at 30 psi in the pressurized storage tank.
Feed water inlet solenoid valve: This solenoid valve turns the water supply to the COMPACT RO system OFF when the storage tank
is full and turns ON when the storage tank needs more water.
Feed water low pressure switch: This is a safety feature designed to make sure there is at least 30 psi being delivered to the COMPACT RO system before the motor starts. This switch protects the pump from running dry due to
no feed water supply.
Rotary vane pump: This pump provides the necessary operating pressure (approx. 180 to 200 psi) to the RO membrane.
|
| Explanation of Optional Features:
|
Float switch for atmospheric storage tank: This option is necessary if you intend to store the RO water in an atmospheric (open storage) water tank. If this option is used, the COMPACT RO system cannot be installed to a pressurized storage tank.
220 volt: The COMPACT RO system is standard 110v power.
Select this option if you prefer 220v. |
Commercial
RO System Technical Guidelines
Commercial
reverse osmosis water treatment is quite complex because very large amounts of
water are processed daily. There are many stringent requirements for the input
water quality for commercial ROs compared to residential RO systems. Commercial
RO systems (at over 400 GPD flow rates) would always require pre-treatment of
the incoming water to assure a flawless operation and membrane/system longevity.
The appropriate pre-treatment depends on local water quality. The most commonly
used pre-treatments are water softeners and back-washing carbon filters for treating
hard and chlorinated water. Other specialty filters can be used when specific
contaminants are present. For example, if you have above 0.5 ppm of iron in your
water, you would need an iron-removal filter in front of the commercial RO system.
When
sizing a system, particularly if system output is critical for you, you need
to understand that the actual flow rate GPD (Gallons Per Day) of any reverse osmosis
system depends on the water pressure, input water temperature and your water conditions
(whether appropriate pre-treatment is applied). While the industry standard temperature
is set at 77 °F, we know that not everyone has 77 °F input water. Below
is a water temperature compensation chart for you to calculate the nominal GPD
of your RO system at different temperatures.
INSTRUCTIONS:
find your water temperature and its factor, divide the RO system GPD by that factor,
and you will get the temperature-corrected output .

solution @ 77 °F water
