Quartz sand filter

The raw water is purified simple by the filter. The filter mainly removes the suspend matter, colloid and other big impurity. If pressure dispersion of the water entering and water out exceeds 10Psi(0.7kg/cm2)or the water out SDI>5, the filter need to be back flushed. Commonly, the filter should be back flushed once before operation every day and also be back flushed with gas once a week.

Activated carbon filter

The active carbon is made of wood, coal, fruit shell (stone) and other carbonaceous material through the method of chemical activation or physical activation. It has a great deal of micro-holes and huge surface, so it has very strong physical adsorption capability to adsorb the organic infecting of the water. The filter mainly removes the organic substance, chlorine, odor, chromo and etc to make the left chlorine ≤ 0.1mg/l. So as protect the RO membrane from damage by the chlorine. The active carbon should be replaced every 12 to 15 months according to the content of the chlorine mostly. Commonly, the filter should be back flushed every week.

High pressure pump

The pump supplies the pressure needed to push water through the membrane, even as the membrane rejects the passage of salt through it. Typical pressures for range from 225 to 375 psi (1.6 to 2.6 MPa). In the case of seawater, they range from 800 to 1, 180 psi (6 to 8 MPa).

Membrane assembly

The RO device removes the hydronium, organic substance, colloid, bacteria and other impurity by the method of membrane. And the water can be desalted and purified. The theory is as follows. The treated water and the untreated water are separated by the membrane; The treated water osmoses to the untreated water. There is osmotic pressure between the two. If the pressure is added to the untreated water and the pressure of the untreated water is bigger than the osmotic pressure, the water of the untreated water osmoses to the opposite position of the water. This applies the reverse osmosis to the desalted water. That is to say the untreated water is purified into the pure water through the RO membrane under adequate pressure. The left water which can not osmosis through the membrane contains a lot of solute and suspended substance, and it will be drained out as waste water.

The water must be pretreated before entering into the RO system, or it will bring damage to the RO membrane.

The RO system not only can be used for desalination, but also for filtering the organic substance and bacteria.

The production of water is monitored by the liquid crystal display conductivity meter.
