Available Options

  • RO membranes are available with brands of
    Filmtec, Hydranautics, Vontron, and Toray

  • Higher pressure of multistage pump for feed TDS above 2,000 ppm or 5,000ppm

  • Digital sensors with remote monitoring

  • Raw water booster pump and controls

* Minimum recovery rate is calculated based on no concentrate recirculation,
  it is possible to increase the overall recovery rate by increasing the concentrate circulation flow.

** Permeate flow rate can vary depending on type of membrane, raw water quality, and recovery rate.
