The main process of pure water equipment :
1, the original water tank (optional)
Store raw water for sedimentation of large sediment particles and other precipitable substances in water. At the same time, it buffers the impact of water pressure instability on the water treatment system in the raw water pipe. (such as pressure sensing reaction caused by low or too high water pressure).
2, the original water pump
Constant system water supply pressure, stable water supply.
3, multi-media filter
The filter with multiple filtration layers is mainly used to remove the sediment, rust, colloidal substances, suspended solids and other particles containing more than 20um in the raw water. It can be backwashed by manual valve control or fully automatic controller. Flush and other operations. Ensure the water quality of the equipment and extend the service life of the equipment.
4, activated carbon filter
The system uses a shell-shell activated carbon filter. The activated carbon not only adsorbs electrolyte ions, but also performs ion exchange adsorption. The adsorption of activated carbon can also reduce the oxygen consumption (COD) of potassium permanganate from 15mg/L (O2) to 2-7mg/L (O2). In addition, due to the adsorption, the concentration of adsorbed and replicated surface increases. It acts as a catalyst, removes pigments, odors, large amounts of biochemical organic matter, reduces residual chlorine values ​​of pesticides, and removes trihalides (THM) and other pollutants from water. Rich and pure water equipment. Manual valve control or fully automatic controller can be used for backwashing, flushing and other operations. Ensure the water quality of the equipment and extend the service life of the equipment. At the same time, the equipment has a self-maintenance system and the operating costs are low.
5, ion softening system / dosing system
In order to dissolve the concentrated discharge of solid matter and the utilization of fresh water, the RO device prevents the concentration of CaCO3, MgCO3, MgSO4, CaSO4, BaSO4, SrSO4, SiSO4 on the concentrated water side of a membrane module after the concentrated water end, especially the RO unit. It is larger than its equilibrium solubility constant and crystallizes out, which damages the original characteristics of the original film, and is rich in single-stage reverse osmosis pure water production equipment. Before entering the reverse osmosis membrane module, an ion softening device or an appropriate amount of scale inhibitor should be used to prevent crystal precipitation of carbonate, SiO2, and sulfate.
6, precision filter
The use of precision filters to remove suspended solids, non-straight particles and colloids in the influent water makes the subsequent operation of the RO system safer and more reliable. The filter element is a 5um meltblown filter element, the purpose is to prevent the upper filter unit from being removed, and impurities missing more than 5um are removed. Preventing the reverse osmosis device from damaging the surface of the membrane, thereby damaging the desalination performance of the membrane.
7. Reverse osmosis system
The reverse osmosis device separates the solvent (usually water) in the solution through a reverse osmosis membrane (or semi-permeable membrane) with sufficient pressure because this process is opposite to the direction of natural permeation and is therefore called reverse osmosis.
The reverse osmosis method can adapt to all kinds of raw water with salt content, especially in the high-salt water treatment project, which can obtain good technical and economic benefits. Shenyang Fushun pure water filling production line. The reverse osmosis method has high salt rejection rate, high recovery rate, stable operation, small floor space and simple operation. The reverse osmosis equipment removes most bacteria, colloids and large molecular weight organic substances while removing salt.
8, ozone sterilizer (optional)
Killing bacteria caused by secondary pollution completely guarantees the hygienic index of finished water.
