Stainless Steel Membrane Shell Reverse Osmosis Pretreatment Filtration Precision Purification Water Equipment

Product description

Stainless steel membrane shell: generally made of 304 or 316 stainless steel material, with good corrosion resistance, and polished inside and outside of the membrane shell. Its function is to accommodate reverse osmosis membrane elements and provide a sealed pressure environment for the reverse osmosis process.

pretreatment system
Multi media filter: usually containing filter materials such as quartz sand, activated carbon, resin, etc., it can remove suspended solids, bacteria, organic matter, iron oxide and other impurities in water.
Activated carbon filter: Utilizing the adsorption properties of activated carbon, it removes harmful substances such as pigments, odors, residual chlorine, colloids, etc. from water.
Softener: mainly used to reduce the hardness of raw water, remove calcium and magnesium ions from water, prevent scaling in subsequent treatment processes, and protect reverse osmosis membranes.
Security filter: Generally using a 5-micron pore size filter element, it can intercept a small amount of mechanical impurities leaked by the pretreatment system, further purify the water quality, and meet the requirements of reverse osmosis inlet water.
Reverse osmosis system: composed of high-pressure pump, reverse osmosis membrane components, etc. The high-pressure pump provides sufficient pressure for the reverse osmosis membrane element, allowing water to pass through the reverse osmosis membrane under pressure, while most harmful substances are intercepted, thus achieving the purpose of purifying water.

Working principle
The raw water first enters the pretreatment system and is treated by equipment such as multi-media filters, activated carbon filters, and softeners to remove large particle impurities, organic matter, residual chlorine, calcium and magnesium ions, reduce water turbidity and hardness, and provide qualified influent for subsequent reverse osmosis treatment. After pre-treatment, the water enters the security filter to further remove small particle impurities, and then enters the reverse osmosis system. Under the action of the high-pressure pump, water passes through the reverse osmosis membrane. Due to the very small pore size of the reverse osmosis membrane, only water molecules and a small amount of ions can pass through, while other harmful substances such as heavy metals, bacteria, viruses, organic matter, etc. are trapped on one side of the membrane, thus achieving the purification and desalination process of water.
characteristic
High filtration accuracy: The pore size of the reverse osmosis membrane can reach 0.0001 microns, which can effectively remove harmful substances such as fine impurities, colloids, organic matter, heavy metals, bacteria, viruses, etc. from water. The desalination rate can usually reach over 96%.
High degree of automation: By adopting a fully automated control system, intelligent operations such as automatic operation, automatic flushing, and fault alarm can be achieved, reducing the complexity and errors of manual operations and improving the stability and reliability of equipment operation.
Stable water quality: It can continuously and stably provide high-quality purified water to meet the water quality requirements of different users. The effluent quality can meet the high standard water demand of industries such as electronics, pharmaceuticals, and food.
Compact structure: The overall structural design is compact, occupying a small area, easy to install and maintain, suitable for various places, including industrial plants and laboratories with limited space.
application area
In the industrial field, it can be used for the preparation of flushing water for electronic components such as integrated circuits and silicon chips in the electronics industry, fine chemical synthesis, chemical product washing and purification in the chemical industry, and boiler feedwater treatment in thermal power plants in the power industry.
In the pharmaceutical field, water purification is used for injection production, biopharmaceutical production, and traditional Chinese medicine preparation production in the pharmaceutical process. It can effectively remove impurities such as microorganisms, endotoxins, and chemicals from water, and improve drug quality.
Food and beverage industry: used for cleaning raw materials, equipment, containers, etc. in the food processing process, as well as purifying production water for beverages, dairy products, alcoholic beverages, etc., to ensure the hygiene, safety, and quality of food and beverages.
Desalination of seawater and brackish water: It can remove salt and other impurities from seawater or brackish water, convert them into drinkable fresh water, and provide clean water sources for islands, ships, offshore drilling platforms, and brackish water areas.
