    Reverse Osmosis/Water Treatment

    Equipment/Water Treatment Device/Water


    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 received.

    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.

    Performance and Structure (specification):

    1). Output of pure water ranges from 8, 000

    gallon per day to 256, 000 gallons per day

    (30 to 1000T/ day, or more).

    2). Resin sprayed coated frame.

    3). Stainless steel, high pressure and multi-

    stage centrifugal pump.

    4). Inlet solenoid valve.

    5). TFC membrane.

    6). Stainless steel vessels or FRP vessels.

    7). Magnetic starter.

    8). Liquid filled high and low pressure


    9). TDS or Conductivity transmitter.

    10). Security filters of 5μ For large


    11). Low and high-pressure cut-off switch.

    12). Built-in automatic membrane cleaning


    13). Dynamic state indicators. Product and

    brine flow meters.

    14). Delayed starting system for electric


    15). NEMA 4 electrical enclosure.

    16). Built-in chemical cleaning system
