FEED WATER PARAMETERS :
? Max. temperature 85° F.
? Max. pressure between 40 ~ 80 psi.
? Max. TDS 2,000 ppm.
? Max. Iron tolerance 0.5 ppm.
? Hydrogen sulfide must be removed.
? Silica tolerance can not be higher than 125 ppm in the concentrate stream.Antiscalant should be considered for any levels over 75 ppm.
?Turbidity should be removed.
? Hardness must be removed.
OPERATING PARAMETERS :
? Max. operating pressure 200 psi.
? Water recovery up to 60% but not recommended to adjust higher than 50%.
? pH range 3-11.
? Flow rates are determined by the membrane mfg’s testing criteria of 1 ,500 ppm NaCI solution, 77°F water temperature, 225 psi at 10 ~ 15% recovery. Actual flow rates may vary depending on the pretreatment, water conditions, system volumn, membrane array and operation pressure.
