    Main process flow of reverse osmosis pure water equipment

    Raw water tank (optional)
    Store raw water, used for sedimentation of large sediment particles in water and other sedimentable substances. At the same time, the impact of the unstable water pressure in the raw water pipe on the water treatment system is buffered. (Such as pressure sensing response caused by too low or too high water pressure).
    2.Pure water pump pure water equipment,
    Constant system water supply pressure and stable water supply.
    3.Quartz sand filter adopts multiple layers of filter, the main purpose is to remove the particles containing more than 20um particles such as sediment, rust, colloidal matter, suspended matter, etc., which can be controlled by manual valve or automatic control. The device performs a series of operations such as back flushing and forward flushing. Ensure the quality of water produced by the equipment and prolong the service life of the equipment.
    4. Activated carbon filter system adopts fruit shell activated carbon filter. Activated carbon can not only adsorb electrolyte ions, but also perform ion exchange adsorption. Activated carbon adsorption can also reduce the oxygen consumption (COD) of potassium permanganate from 15mg / L (O2) to 2-7mg / L (O2). In addition, the concentration of the surface being adsorbed and replicated is increased due to adsorption, so It plays a catalytic role, removes pigments, odors, large amounts of biochemical organic matter in water, reduces the residual chlorine value of water and pesticide pollutants, and removes trihalides (THM) and other pollutants in water. Optional manual valve control or fully automatic controller for back flushing, forward flushing and other operations. Ensure the quality of water produced by the equipment and prolong the service life of the equipment. At the same time, the equipment has a self-maintaining system and the running cost is very low.
    5. I / O softening system / dosing system R / O device In order to dissolve the concentrated discharge of solid matter and the use of fresh water, in order to prevent CaCO3, MgCO3, MgSO4 from appearing in the concentrated water side, especially the concentrated water side of the last membrane module of the RO device The concentration product of CaSO4, BaSO4, SrSO4, and SiSO4 is larger than its equilibrium solubility constant and crystallizes out.It should damage the original characteristics of the membrane. Before entering the reverse osmosis membrane module, an ion softening device or an appropriate amount of scale inhibitor should be used to prevent carbonic acid. Crystals of salt, SiO2, and sulfate precipitate.
    6. The security filter uses precision filters to remove suspended solids, non-curvilinear particles and colloids in the incoming water, making the subsequent equipment such as the RO system safer and more reliable. The filter element is a 5um meltblown filter element, the purpose of which is to prevent the upper filtering unit from removing impurities larger than 5um. Preventing the entry of the reverse osmosis device damages the surface of the membrane, thereby damaging the desalination performance of the membrane.
    7. The high-pressure pump adopts a vertical multi-stage stainless steel centrifugal high-pressure pump. This is an important component of the RO host. Its role is to deliver a certain amount of water to the reverse osmosis membrane with a certain pressure. Its quality has a great impact on the whole machine. During use, it should be ensured that no idling and long-term overload operation are not allowed. Air is often removed as required, and electrical components should be dried.
    8. Primary reverse osmosis system The reverse osmosis device uses sufficient pressure to separate the solvent (usually water) in the solution through a reverse osmosis membrane (or semi-permeable membrane), because this process is opposite to the direction of natural infiltration. It is called reverse osmosis.
    The reverse osmosis method can adapt to various types of raw water with salt content, especially in high-salt water treatment projects, and can obtain good technical and economic benefits. The reverse osmosis method improves the desalination rate, high recovery rate, stable operation, small footprint, and easy operation. The reverse osmosis equipment removes most of the bacteria, colloids and large molecular weight organic matter while removing salt.
    9. The semi-finished water tank stores pure water without disinfection.
    10.Ozone sterilizer (optional)
    Ozone is used to kill bacteria and viruses in the water, prevent new bacteria from being produced in the water tank, and completely ensure the quality of pure water.
    11. The finished water tank stores the sterilized finished water and supplies water points.
    12. The booster pump ensures the water supply and pressure at the water point.
