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 .

FEED WATER REQUIREMENTS :
OPERATING PARAMETERS :

Temperature 85 °F 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 33-35%.

Flow rates are determined by membrane manufacturer's testing criteria of 1500 ppm NaCl solution @ 77 °F 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.
