Introduction to Reverse Osmosis Pure Water Equipment:
Reverse osmosis pure water equipment passes raw water through fine filters, granular activated carbon filters, compressed activated carbon filters, etc., and then pressurizes it through a pump. It uses a reverse osmosis membrane (RO membrane) with a pore size of 1/10000 μ m (equivalent to 1/6000 the size of Escherichia coli and 1/300 the size of a virus) to turn high concentration water into low concentration water. At the same time, it isolates industrial pollutants, heavy metals, bacteria, viruses, and other impurities mixed into the water, thereby achieving the physical and chemical indicators and hygiene standards specified for drinking. It is the choice for the human body to replenish water in a timely manner So people call this type of water production machine a reverse osmosis purified water machine.
The reverse osmosis pure water equipment adopts fully automatic control mode to reduce the impact of human error operation on the equipment belt. The design of a reduction system in the pretreatment system addresses the irreparable impact of excessive residual chlorine on the reverse osmosis membrane. The selection of reverse osmosis membrane adopts imported reverse osmosis membrane from the United States, with a service life of up to 3 years and a effluent conductivity of less than 5us. The pumps selected are domestic Southern pumps and imported Grundfos pumps, which have low operating noise and long service life. We use Dow's professional design software, and the recovery rate can reach over 65%. The high degree of automation, simple operation, stable water quality, and low operating costs have been highly praised.
Reverse osmosis is a modern and novel technology for treating pure water. By using reverse osmosis components to improve the purity of water and remove impurities and salts from the water. The purified water we drink in our daily lives is treated with reverse osmosis equipment, resulting in clear water quality.
Reverse osmosis technology is a membrane separation technology driven by power difference. With the promotion of this technology, China has begun to use reverse osmosis technology. The purified water equipment on the market adopts reverse osmosis membrane treatment technology, and has undergone certain improvements and design innovations in China. The technology is already very mature.
A reverse osmosis membrane has been designed in the reverse osmosis purified water equipment. The pressure on both sides of the membrane is different. With the pressure on both sides as the driving force, the raw water is compressed through the reverse osmosis membrane. The salt with lower concentration will permeate towards the salt with higher concentration. The equilibrium state that can be achieved is the osmotic pressure of the liquid. When the pressure on one side of the saltwater is opposite to the osmotic pressure on the other side, a reverse flow occurs, resulting in a reverse osmosis process. The reverse osmosis purified water equipment adopts this technology and adopts intelligent control of automatic water supply and cut-off, which is the purified water equipment
Composition of reverse osmosis pure water equipment system:
Pre treatment: generally includes raw water pump, dosing device, quartz sand filter, activated carbon filter, precision filter, etc. Its main function is to reduce the pollution index of raw water and other impurities such as residual chlorine, in order to meet the inlet requirements of reverse osmosis. The equipment configuration of the pretreatment system should be determined according to the specific situation of the raw water.
Reverse osmosis: mainly composed of multi-stage high-pressure pumps, reverse osmosis membrane components, membrane shells (pressure vessels), brackets, etc. Its main function is to remove impurities from water and make the effluent meet the requirements for use.
Cleaning: It mainly consists of cleaning water tanks, cleaning water pumps, and precision filters. When the reverse osmosis system is contaminated and the effluent indicators cannot meet the requirements, it is necessary to clean the reverse osmosis system to restore its effectiveness.
Electrical control: It is used to control the normal operation of the entire reverse osmosis system. Including instrument panel, control panel, various electrical protections, electrical control cabinet, etc.
Process flow of reverse osmosis pure water equipment:
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).
Raw water pump:
Constant system water supply pressure, stable water supply volume.
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.
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 (O2) to 2-7mg/L (O2). 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 compounds, reducing the residual chlorine value and pesticide pollutants in water, and removing trihalides (THM) and other pollutants from water. At the same time, the equipment has a self maintenance system and low operating costs.
Ionic softening system/dosing system:
In order to concentrate and discharge solid substances for dissolution and utilize fresh water in the R/O device, and to prevent the concentration product of CaCO3, MgCO3, MgSO4, CaSO4, BaSO4, SrSO4, SiSO4 on the concentrated water side, especially on the last membrane component of the RO device, from exceeding its equilibrium solubility constant and crystallizing, damaging the proper characteristics of the membrane components, an ion softening device or an appropriate amount of scale inhibitor should be used to prevent carbonate from entering the reverse osmosis membrane component, SiO2， The precipitation of sulfate crystals
Precision filter:
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.
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.
Ozone sterilizer/UV sterilizer (optional):
Kill bacteria generated by secondary pollution to ensure the hygiene indicators of finished water
