Reverse osmosis system is the core component of the entire pure water system, only through reverse osmosis to achieve the standard of pure water. The reverse osmosis system mainly adopts the membrane filtration process. Then water molecules can pass through the reverse osmosis membrane. Some other ions such as calcium, magnesium and sodium are discharged with the wastewater. The following components of this system.
1. Precision filter
Mainly filter large particles of molecules in the water.
2. Special high-pressure pump
Provide strong power for reverse osmosis equipment.
3. Reverse osmosis membrane
Reverse osmosis membrane uses membrane filtration technology. Let the water molecules through some other ions can not pass to achieve the purpose of water purification.
As the dependence of pure water production is very important. So to produce pure water must be to choose the place where the quality of raw water is better. Such as mountain springs, deep wells and so on. Here involves a very important index is "conductivity". Generally speaking, the lower the conductivity. The purer the water. The water treatment process is used to use the reverse osmosis system. After treatment, the water can generally reach 90% - 99% desalination rate. Here I introduce the components of this system.
1. Raw water pump
Raw water pump is for the raw water pretreatment system to provide the role of raw water pressure. If the raw water pressure can be completely without this equipment. General requirements for raw water pressure >= 0.3MP
2. Raw water tank
The role of the raw water tank is more simple, is the storage of raw water. This is afraid of raw water in case of supply for a transit.
3. Quartz sand filter
This equipment is mainly used to filter microorganisms in the water, dust so that the raw water to achieve the purpose of clear.
4. Activated carbon filter
This equipment is mainly to filter the residual chlorine in the water.
5. Dosing system (cation exchange system)
Small systems use cation exchange system; large systems use dosing system to add scale inhibitors directly.
