Raw water pump
The raw water entering the system is required to have stable flow and pressure, and the purpose is to prevent the influence of water inlet fluctuation on the operation of the system and ensure the stability of the water inlet amount of the system.
Iron and manganese removing filter
The multimedia filter is an important pretreatment device of the system. When the water flow containing suspended impurities passes through the granular filter material, most of the suspended impurities in the water are intercepted, and a small amount of impurities move downwards due to poor adhesion and are intercepted by the lower layer of filter material. This is the mechanical sieving function of the filter material, and in addition, the adhesion between the suspended particles and the filter material particles further intercepts the suspended impurities.
After the multi-medium filter works for a period of time, because the filter layers intercept more and more dirt, gaps among the filter layers are gradually blocked by impurities, and the flow of filtered water is sharply reduced. To restore the fouling cut-off capacity of the equipment, the equipment must be backwashed periodically. Backwashing generally adopts a method of combining air washing and water washing.
Precision filter
The precision filter is provided with a large-flux filter element with the diameter of 10 mu m, so that solid particles, bacterial corpses, pre-stage crushing filter materials and other impurities in the fluid are further removed. Any particles with a particle size greater than 10 μm will be trapped on the surface of the filter element.

PAC medicine adding device
Because the raw water contains a large amount of suspended matters, colloids and other impurities which are always provided with a certain amount of like charges and mutually repel each other, the impurities are difficult to automatically aggregate into large particles and are difficult to separate and remove. The PAC flocculant can form long-chain multifunctional groups with charges in water, has the function of compressing colloid double electric layers, can also play a role of neutralizing opposite charges, and each group can adsorb middle-particle impurities such as suspended matters, organic matters, colloid and the like dispersed in water to enable the middle-particle impurities to be agglomerated into large-particle alum flocs, so that subsequent equipment can be conveniently and effectively removed.
NaCLO dosing device
The system adopts the addition of oxidant sodium hypochlorite solution.
The water body of nature contains microorganisms including bacteria, fungi, algae, viruses, protozoa, and the like. If raw water containing microorganisms directly enters a reverse osmosis membrane element without sterilization treatment, the microorganisms are concentrated on the surface of the membrane element under the reverse osmosis concentration action to form a microbial membrane, the water yield and the desalination rate of the membrane element are seriously influenced, and the telescope phenomenon is caused by the increase of pressure drop. Moreover, the cleaning effect of the membrane element is not very good after the membrane element is polluted by microorganisms, so that the raw water containing the microorganisms, especially sewage or reclaimed water, must be sterilized in the pretreatment.
In addition, the hypochlorous acid can oxidize residual iron ions in the water to generate quadrivalent iron, so that the system is convenient to remove.
NaHSO3Medicine adding device
After the oxidant is added into raw water, a small amount of hypochlorous acid is remained, and free chlorine in the water inlet of the RO device is reduced to be below 0.05ppm, so that the requirement of a reverse osmosis membrane assembly can be met. Sodium bisulfite is a typical reducing agent of choice for larger RO plants.
