2T/h secondary reverse osmosis equipment

2T/h secondary reverse osmosis equipmentIt is a modern new type of pure water treatment technology. 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.

The country that first used reverse osmosis technology was the United States, which invented membrane separation technology powered 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.

Reverse osmosis technology is increasingly widely used due to its unique advantages. The cleaning problem of reverse osmosis water purification equipment may cause losses to many users with weak technical capabilities, so it is necessary to manage the reverse osmosis equipment well to avoid serious problems.

Under normal operating conditions, the reverse osmosis membrane of the secondary reverse osmosis equipment may also be contaminated by inorganic scale, colloids, microorganisms, metal oxides, etc. These substances deposited on the membrane surface can cause a decrease in the output of the reverse osmosis device of the water purification equipment, a decrease in desalination rate, an increase in pressure difference, and even irreversible damage to the membrane. Therefore, in order to restore good permeability and desalination performance, chemical cleaning of the membrane is necessary.

Generally, cleaning should be done once every 3 to 12 months. If cleaning is necessary every month, it indicates that the pre-treatment system should be improved and the operating parameters adjusted. If cleaning is required once every 1-3 months, it is difficult to determine whether the pre-treatment system needs to be improved, as it is necessary to improve the operational level of the equipment.

In order to concentrate and discharge solid substances for dissolution and utilize fresh water in R/O devices, and to prevent the concentration product of CaCO3, MgCO3, MgSO4, CaSO4, BaSO4, SrSO4, SiSO4 on the concentrated water side of a membrane module, especially after 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 module, SiO2， The precipitation of sulfate crystals

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 surface of the damaged membrane, thereby damaging the desalination performance of the membrane.

It is the process of using 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 it is in the opposite 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.
