Reverse osmosis equipment compositionRaw water → original water tank → raw water pump → quartz sand filter → activated carbon filter →

softener → precision filter → high pressure pump → reverse osmosis main engine part →RO water tank → water point

1. Quartz sand filterQuartz sand filter is to remove suspended solids in water, sediment, colloid, impurities such as large particles, reduce the

turbidity of water treated with quartz sand water pollution index SDI 4 or less, can prevent the fouling of reverse osmosis membrane surface

(including CaCO3 and CaSO4, SrSO4, SiO2, iron, aluminum oxide, etc.), prevent the colloidal substances and suspended solid particulate

fouling, prevent organic matter and microbial fouling, protection of reverse osmosis membrane;

2. Activated carbon filterActivated carbon filter

is mainly through the chemical adsorption of activated carbon, remove the odor, organic matter, iron and residual chlorine in the water, at the

same time, reduce the color of the water, turbidity, reduce the pollution of reverse osmosis, after the treatment of residual chlorine ≤0.1 PPM

3. Security filtersPP cotton filter element with a diameter of 5um was built in to remove particles with a diameter of more than 5um that could

not be disposed of in the previous pretreatment process, so as to protect RO membrane from less pollution and ensure the safe and normal

operation of RO reverse osmosis membrane 3. Water softenerThe water softener is mainly used to replace calcium and magnesium plasma

in the water by sodium ion resin to reduce the hardness of the water and protect the good working conditions of the reverse osmosis

membrane in the subsequent reverse osmosis system

4. Reverse osmosis main engine partThis section includes the reverse osmosis

membrane, membrane shell, associated piping, valves, instrumentation, flushing system, and electrical control system.The reverse osmosis

membrane adopts the original imported dow membrane or other brands of reverse osmosis membrane from the United States. The

desalination rate of single branch membrane is ≥ 98%, and the conductivity of reverse osmosis water production is < 10us/cm.
