Question: What Factors Affect The Quantity And Quality Of RO Water Produced?

ANSWER: There are four major variables to consider:  1. PRESSURE. The greater the water pressure, the better the quantity and quality of the water produced. Water pressure of 60 psi is ideal. To maintain a constant  60 PSI you should consider including a booster pump.  It is the pressure of water that forces the water through the membrane for purification and flushes the rejected solids away. Low water pressure will result in reduced production and premature fouling of the membrane. The ideal pressure for operating an RO System, as noted above is 60 PSI. Pressure below 40 PSI is generally considered insufficient, and should be boosted using a pressure booster pump. 2.TEMPERATURE. 77*F is the ideal water temperature for R.O. 40*F water will cause the production of R.O. water to fall to half of that at 77*F. The maximum water temperature recommended is 85*F. 3.TOTAL DISSOLVED SOLIDS (TDS). The higher the amount of dissolved contaminants in the water, the lower the quantity of water produced. A high level of *TOTAL DISSOLVED SOLIDS can be overcome with additional water pressure. 4. MEMBRANE. Different RO membranes have different characteristics. Some produce more water than others; some have better contaminant rejection capabilities; some have greater resistance to chemical abrasion for longer life. The Thin Film Composite(TFC) membranes made by Filmtec and CSM, combine the best of these characteristics and are considered among the finest membranes in the world.
