Product Introduction
Reverse osmosis pure water machine
1、 Introduction
Reverse osmosis is the process of applying a pressure greater than the osmotic pressure to a solution, allowing water to pass through a specially designed semi permeable membrane and separate from the solution. Because this process is opposite to infiltration, it is called reverse osmosis. According to the different osmotic pressures of various materials, a reverse osmosis method with a pressure greater than the osmotic pressure can be used for a certain solution to achieve the purpose of separating, extracting, purifying, and concentrating the solution. The reverse osmosis device is mainly used to separate the range of ions in the solution. It does not require heating and does not have a phase change process, so it consumes less energy than traditional methods. Reverse osmosis has a small volume, simple operation, and a wide range of applications. Using reverse osmosis equipment to treat industrial water does not consume a large amount of acid and alkali, does not cause secondary pollution, and its operating costs are relatively low.
2、 Process flow:
Raw water → Raw water tank → Raw water booster pump → Multi medium filter → Activated carbon filter → Softener → Precision filter → High pressure pump → Primary reverse osmosis equipment → Pure water tank → Pure water pump → Water point (effluent conductivity: ≤ 10us/cm)
3、 Process description
1. Raw water tank
Store raw water for settling large sediment particles and other precipitable substances in water. Simultaneously buffering the impact of unstable water pressure in the original water pipe on the water treatment system. (such as pressure sensing reactions caused by low or high water pressure).
2. Raw water pump
Constant system water supply pressure, stable water supply volume.
3. Multi media filter
The main purpose of using a filter with multiple filtration layers is to remove substances such as sediment, rust, colloidal substances, suspended solids, and other particles with a particle size of more than 20um in the raw water. Manual valve control or fully automatic controller can be used for a series of operations such as backwashing and forward flushing. Ensure the quality of water produced by the equipment and extend its service life.

Ensure the quality of water produced by the equipment and extend its service life.
4. Activated carbon filter
The system adopts a fruit shell activated carbon filter, which can not only adsorb electrolyte ions but also perform ion exchange adsorption. Activated carbon adsorption can also reduce the oxygen demand (COD) of potassium permanganate from 15mg/L (02) to 2-7mg/L (02). In addition, due to the adsorption effect, the concentration of adsorbed and replicated on the surface increases, thus playing a catalytic role, removing pigments, odors, a large amount of biochemical organic matter, reducing residual chlorine value and pesticide pollutants in water, and removing trihalides (THM) and other pollutants in water. Manual valve control or fully automatic controller can be used for a series of operations such as backwashing and forward flushing. Ensure the quality of water produced by the equipment and extend its service life. At the same time, the equipment has a self maintenance system and low operating costs.
5. Sodium ion softener
In order to concentrate and discharge solid substances and utilize fresh water in R/O devices, and to prevent the concentration product of CaCO3, MgCO3, MgSO4, CaSO4, BaS04, SrS04, and SiSO4 from exceeding their equilibrium solubility constants and crystallizing on the concentrated water side, especially on the last membrane module of RO devices, which may damage the membrane components, ion softening devices or appropriate scale inhibitors should be used before entering the reverse osmosis membrane module to prevent the crystallization of carbonates, SiO2, and sulfates
6. Precision filters
By using precision filters to remove suspended solids, non straight particles, colloids, and other substances remaining in the influent, the subsequent equipment such as the RO system can operate more safely and reliably. The filter element is a 5um melt blown filter element, which aims to remove impurities larger than 5um that are missed by the upper filtration unit. Prevent it from entering the reverse osmosis device and damaging the surface of the membrane, thereby damaging the desalination performance of the membrane.
7. Reverse osmosis system
Reverse osmosis device is a process that uses sufficient pressure to separate the solvent (usually water) in a solution through a reverse osmosis membrane (or semi permeable membrane), which is called reverse osmosis because this process is opposite to the direction of natural permeation. The reverse osmosis method can adapt to various types of raw water with high salt content, especially in water treatment projects with high salt content, and can achieve good technical and economic benefits. The desalination rate of reverse osmosis is improved, the recovery rate is high, the operation is stable, the footprint is small, and the operation is simple. The reverse osmosis equipment not only removes salt, but also removes most bacteria, colloids, and high molecular weight organic matter.
