Nanjing Shuaibo: Introduction to the main process flow of reverse osmosis pure water equipment

Foreword: Nanjing Shuaibo Machinery Equipment Factory is a high-tech enterprise specializing in the production of complete sets of fluid equipment such as two-stage reverse osmosis pure water equipment , multi-effect distilled water machine and liquid distribution system. It has been committed to the development of China's water treatment industry. With the spirit of enthusiasm, advanced technology and rich practical experience, we provide our customers with quality and stable pre-sales and after-sales services in various water treatment fields.

1. Raw 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 pump constant system water supply pressure, stable water supply.

3. The multi-media filter uses a filter with multiple filtration layers. The main purpose is to remove the sediment, rust, colloidal substances, suspended solids and other particles containing more than 20um in the raw water. It can be controlled by manual valve or fully automatic controller. Backwashing, flushing, etc. Ensure the water quality of the equipment and extend the service life of the equipment.

4. The activated carbon filter 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. 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 R / O device in order to dissolve the concentrated discharge of solids and the use of fresh water, in order to prevent the presence of CaCO3, MgCO3, MgSO4, CaSO4 on the concentrated water side of a membrane module after the concentrated water end, especially the RO unit Zui The concentration of BaSO4, SrSO4, and SiSO4 is greater than the equilibrium solubility constant and crystallizes out. The original characteristics of the damaged membrane are damaged. Before entering the reverse osmosis membrane module, the ion softening device or an appropriate amount of scale inhibitor should be used to prevent the carbonate. , SiO2, sulfate precipitation of crystals.

6. The precision filter uses a precision filter to remove suspended solids, non-straight particles and colloids in the influent water, making the subsequent operation of the RO system safer and more reliable. The filter element is a 5um meltblown filter element, the purpose of which is to remove impurities larger than 5um which are leaked from the upper filter unit. Preventing it from entering the reverse osmosis device damages the surface of the membrane, thereby damaging the desalination performance of the membrane.

7. The reverse osmosis system 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 infiltration, so it is called penetration. 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. 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)

Kill the bacteria caused by secondary pollution to completely ensure the hygiene index of the finished water.
