OPERATING PARAMETER
•
Working pressure: 40 to 80 psi feed water pressure required. If input pressure is below 40 psi, a booster pump or a
permeate pump is needed. We have a RO system with built-in permeate pumps, and we also carry booster pumps.
If the input water pressure is above 80 psi (you must use a pressure regulator to step down the pressure). We
also carry small pressure regulators just for the RO system.
•
Working temperature: 100 ~ 40 deg. F ( 37 ~ 4 deg. C )
•
If feed water has hardness level above 300 ppm, we recommend putting a water softener prior to the RO system.
•
If feed water has iron, rust problem, we recommend putting an iron filter prior to the RO system.
•
If feed water has bacteria problem, we recommend putting an ultra violet sterilizing system prior to RO system.
