Equipment summarize:
Reverse osmosis system is using city water as raw water, then treat water by Pre-filter (water softener is optional), reverse osmosis membrane. It can remove particle, colloid, organic impurity, heavy metal ion, bacteria, virus in water, and it can also remove 99% dissolved salt.
The whole system desalination rate can reach 96%-99% to make permeated water conductivity<10 us/cm. Dense water also won't polluted environment. Reverse osmosis equipment no need to consider about input water quality too much. And the main features of RO equipment is no need to do any regeneration, it can be keep stable for long time.
The basic working principle of reverse osmosis
1. Using a special high-pressure water pump, the raw water is added to a pressure of 6-20 kg, so that the raw water permeates through the reverse osmosis membrane with a pore diameter of only 0.0001 μm under the action of pressure.
2, Chemical ions and bacteria, fungi, virions can not pass, with the discharge of wastewater, only allow water molecules and solvents less than 0.0001 microns to pass.
3. The security filter is equipped with a filter element with a filter aperture of 5μm. These filters filter out any particles larger than 5μm.
4. The more common type of permeable membrane is a polyamide membrane, and the membrane type is a wound composite membrane. The membrane has a salt removal rate of 99.5%.
5, Because the RO membrane is susceptible to the pH value, residual chlorine and water temperature in the water, the RO membrane has strict requirements on the water quality before the operation:
PH value: 3~10
Residual chlorine value: <0.1mg/L
SDI15 value: <5.0
Water temperature: <45 °C
Reverse osmosis system is using city water as feed water.
Pre-treatment filters always contain quartz sand filter, activated carbon filter, water softener and security filter. Main purpose is to remove sludge, rust, colloid, suspended solids, color, odor, biochemical organic impurity in raw water. And pre-filters can also reduce water residual chlorine and pesticide and other harmful pollutions. If raw water in high hardness, we will need to add water softener to protect reverse osmosis membrane.
Features
¶ Optimal Configuration, computer-aided design, efficient power with low consumption.
¶ High efficiency filter, multi-grade stainless steel high pressure centrifugal pump, the world-renowned brands such as membrane components are standard equipment, excellent performance, can operate continuously for long time.
¶ Stable water quality: Advanced water testing control and excellent maintenance program to ensure water quality long-term stability.
¶ Highly intelligent ,especially for large and medium projects.
¶ Applies to a wide range of raw water temperature: the brackish water desalination unit has its own patent design techniques to be at 5 °C-39 °C in the temperature range of full load, the water temperature decreases will not affect output water capacity to ensure that customers are able to get rating produced water capacity.
¶ Modularized design, easy installation.
This water treatment system uses mechanical filters, activated carbon filter as a pre-class treatment, the effective removal of suspended solids in raw water, sediment particles , organic colloids, organic matter, odor, chlorine and other impurities, with pre-programmed as a reverse osmosis desalination plant to remove the raw water. Most of the dissolved salts, bacteria, hot stream and so on, to ensure finished water quality standards.
