    Source Water Preparation for Large RO
    To prevent premature membrane fouling, to increase pure water to waste water ratio

    Large RO membranes are expensive, hence, most source water is pretreated so as not to foul them up ahead of their natural life. The cleaner the water, the longer the membranes will last. We then can set the pure water recovery rate that much higher, thus saving on water bills.

    Source water quality requirements

    • Water temp: 85F max
    • TDS: 2,000 ppm max
    • Iron tolerance: 0.5 ppm max
    • Hydrogen sulfide: must be removed
    • Silica tolerance: less than 125 ppm, antiscalant should be considered for over 75 ppm
    • Turbidity: must be removed
    • Hardness: over 10 gpg should be softened
    • pH range: 3-11
    A source water analysis is recommended before considering a commercial/industrial RO system. We can help you pretreat water for most conditions as discussed below. The throughput capacity of the pretreatment equipment must be sufficient to adequately filter the sum total of the permeate flow (RO GPD rating) and the anticipated waste water flow into drain.

    At lower source water temperatures of less than 77F (25C), actual RO production will be less than the system GPD rating. To estimate the actual production, GPD rating has to be divided by 1.19 at 68F (20C), by 1.47 at 59F (15C), by 1.89 at 50F (10C), by 2.58 at 41F (5C). The temperature derating effect must be included in your system design consideration.       Top

  • Hardness, TDS and RO GPD determine the softener size, generally the larger the better
  • Calender clock backwash takes place at a preprogrammed interval
  • Single tank softener also available, less expensive but lockout logic must disable RO while softener is regenerating
