1. Introduction:

Underground water RO water treatment system is a membrane-technology filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.



2. Stages of Filtration of underground water RO water treatment system

1). Sediment Stage: Removes rough particles, sand and rust.
2). Quartz sand stage: Lower the turbidity of feed water (NTU)and sludge density index (SDI) values
3). Carbon stage: Removes chlorine and chemicals which would otherwise damage the membrane.
4). Resin stage: Purolite ion-exchange.
5). Reverse osmosis stage: Removes dissolved solids and all that are bigger than water molecule.
6. )Final Carbon stage: To improve the taste
7). Ozone sterilization: To kill microorganisms.
8). Storage tank
9. )UV sterilization: To kill microorganisms.



3. Advantage of underground water RO water treatment system(
1). Can production water continuously and highly automatic
2). No need the chemical regeneration, easy operation
3). RO system choose the import USA DOW membrane
4). Automatic switch on when low water level, and switch off when high water level
5). RO membrane can backwash automatic and reduce thepollution.
6). Water shortage protection for multi-stage pump
7). Porduction water condutivity meter can test the monitoring quality on line contionuosly.
8). Low operation Cost and Long life span
9). Easily control and Maintained.
10). Auto membrane flushing
11). Environmental protection, Low power consumption
12) Auto flush/backwash
13) Low /high pressure protection
