Overview

  • China Pure Water System What is Reverse Osmosis?
    RO is a kind of newly developed membrane separation technology in the 1960s. It is working on the principle that water pass through the RO membrane whose bore diameter is 1/10000um (1/60000 size of Escherichia coli, 1/3000 size of virus) from higher concentrated side to the lower one by pressurize. So that the industrial pollutants and impurities such as heavy metal ions, bacteria, viruses separated from the input water.
    RO unit is the key part of the whole system as it determines the output water quality. It mainly consists of booster pumps, membrane shell, RO membrane, control circuit and so on. The salinity filtering ability of RO host can be above 99% if with reasonable design. So the design reasonability will directly determine the cost-effective and operating convenience of the system. And power-saving, operating pressure, transmission and desalination rate and saltness of output water of RO membrane should be taken into consideration when design.
    Single Pass RO VS Double Pass RO
    Think of a pass as a stand alone RO system, the difference between a single pass RO system and a Double Pass RO Pure Water System is that the time product water passed through the RO membrane. With a double pass RO, the permeate from the first pass becomes the feed water to the second pass (or second RO) which ends up producing a much higher quality permeate.
    Besides producing a much higher quality permeate, a double pass system also allows the opportunity to remove carbon dioxide gas from the permeate by injecting NaOH between the first and second pass. By adding NaOH after the first pass, you increase the pH of the first pass permeate water and convert C02 to bicarbonate (HCO3-) and carbonate (CO3-2) for better rejection by the RO membranes in the second pass. This can't be done with a single pass RO because injecting caustic and forming carbonate (CO3-2) in the presence of cations such as calcium will cause scaling of the RO membranes.
    And a generally used double pass RO pure water system(inlet tap water) is showed as following:
