This is our most durable reverse osmosis system with unmatched value in quality, convenience, and price. NSF-grade high quality parts are used to build this tough system. All APEC compact commercial RO systems are constructed of premium components, high quality filters and membranes to guarantee high rejection rates and output speed.

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 50% feed flow recovery. This means that for every gallon of product water produced, 1 gallon flows to the 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 50 psi 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.

TFC extra low energy membrane

Super high flow, high rejection and consistently performing to deliver excellent performance in terms of flux, salt and organics rejection, and microbiological resistance.

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 come in standard 110v power. Select this option in the upgrade area if you prefer 220v.

Tank & Tank Ball Valve

Pressurized Water Storage Tank in 3 sizes (TANK-34 , TANK-44, and TANK-86) and Optional Tank Ball Valve (TBVAL1-14X3-8)

Temperature 85 DegreeF maximum pH range 3-11 Input Pressure 40-80 psi maximum
Operating pressure 200 psi maximum

Hardness over 10 gpg should be softened.

TDS 2000 ppm maximum.

Iron 0.5 ppm maximum.

Turbidity should be removed.

Hydrogen sulfide must be removed.

Silica needs to be less than 125 ppm in the concentrate stream, anti-scalant should be considered for any levels over 75 ppm.

Water recovery is factory set at 50%.

Flow rates are determined by membrane manufacturer's testing criteria of 1500 ppm NaCl solution @ 77 DegreeF water temperature and 225 psi at 10-15% recovery.

Actual flow rates may vary depending on the pre-treatment used, water conditions, membrane array, and applied pressure.

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 DegreeF, we know that not everyone has 77 DegreeF 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.
