It is very important as a support for pure water production. Therefore, to produce pure water, we must choose a place with better raw water quality. Such as mountain springs and deep wells. A very important index involved here is "conductivity". Generally speaking, the lower the conductivity. The purer the water. At present, all the water treatment processes used are reverse osmosis systems. The desalting rate of water after general treatment can reach 90%-99%. This is an integral part of this system.
1. Raw water pump
Raw water pump is used to provide raw water pressure for raw water pretreatment system. If the raw water has pressure, this equipment can be completely unnecessary. General Requirements for Raw Water Pressure; = 0.3 MPa
2. Raw water tank
The function of raw water tank is simpler, and it is used to store raw water. This is because of the fear that raw water cannot be transported (usually adding a float switch will make the whole system more automatic).
3. Quartz sand filter
Quartz sand filter material is used to remove suspended solids, silt and impurities of larger particles in raw water and reduce the turbidity of water. But also can make organic matter, bacteria, viruses and so on. With the decrease of turbidity, a lot of turbidity in water is removed, which creates good conditions for disinfection after filtration.
4. Activated carbon filter
Using the adsorption capacity of activated carbon, the organic matter, free residual chlorine, colloid, particles, microorganisms, some metal ions and decoloration in raw water can be effectively adsorbed.
5. Softening system (batching system)
Using the exchange performance of ionic resin, calcium and magnesium ions in raw water can be removed to prevent scaling of subsequent equipment, but the operation is labor-consuming and material-consuming. Now the dosing system is changed to directly add scale inhibitor into the tank.
Reverse osmosis system is the core component of the whole pure water system, and only through reverse osmosis can the standard of pure water be reached. The reverse osmosis system mainly adopts membrane filtration process. Then water molecules can pass through the reverse osmosis membrane. Others, such as calcium, magnesium and sodium, are discharged together with the wastewater. The following components of the system.
1. Precision filter
This filter mainly filters out large particles in water.
2. Special high-pressure pump
Generally, the high-pressure pumps we use here are special pumps for South China. Provide powerful power for reverse osmosis equipment.
3. Reverse osmosis membrane
Reverse osmosis membrane adopts membrane filtration technology. Letting water molecules pass through other ions cannot achieve the purpose of purifying water.
Other auxiliary systems, such as ozone sterilization system, lamp inspection and filling system. Ultraviolet rays can also be used for sterilization, and there will be no residual ultraviolet rays. Nowadays, many people abroad like to use ultraviolet rays.
