    Reverse Osmosis/ Water Treatment Equipment/ Water Treatment

    Device/ Water Treatment

    To remove salt anf other material ions from raw water

    The system is specifically designed for the high water

    output reverse osmosis system, and the maximum water output

    can reach as high as 256, 000 gallons per day. Meanwhile,

    different designs are applied to different water qualities,

    irrespective of tap water or brackish water: The system can

    all be made to order in accordance with the different water


    The reason behind the application of the reverse osmosis

    membrane to the production of pure water lies in the fact

    that its pore is so small ( 0.0001 μ =10 angstroms) and it

    can compare with the diameter of water molecules; While the

    diameters of the molecules of the other metals and chemical

    compounds are larger than the diameter of water molecules:

    As to viruses and bacteria, their diameters are even further

    larger. Therefore, only the water molecules can osmose to

    the opposite side of the membrane in a reverse way; While

    the other elements, viruses and bacteria can not infiltrate

    to the other side. This is just the reason for the reverse

    osmosis membrane capability of obtaining pure water.

    The table demonstrates the rejection rate of the reverse

    osmosis membrane with relation to various substances in

    water. On average, the rejection rate is as high as 98% .

    Thereby the reverse osmosis ( R. O) equipment is quite well


    The standard equipment units included in the present system

    consists of the following: Security filters of 20 μ And 5

    μ For the large specifications; High- pressure multi- stage

    centrifugal pumps. The latest generation of compound

    membranes; The entire instrumentation system; High- pressure

    regulator; Conductivity transmitter ( or resistivity

    transmitter) and the complete built- in chemical membrane

    cleaning system.

    All the parts are of the high quality and are assembled onto

    a compact frame. This R. O. System can be made to order in

    accordance with the requirements of the customers, and there

    will present no problem even if TDS reaches 10, 000 ppm.
