Reverse osmosis systems typically consist of two main units: pre-treatment and RO. The selection of RO membrane types can be tailored to meet the user's specific material and water quality requirements.

The RO membrane is a specialized process membrane made of high molecular materials. It allows only water molecules to permeate while blocking solutes. By applying high pressure using a pump, water molecules can permeate through the semi-permeable membrane to the other side when the pressure of the feedwater exceeds the osmotic pressure. This results in the production of purified water.

Inorganic salts, heavy metal ions, organic substances, bacteria, colloids, and other substances that are dissolved or undissolved in the feedwater cannot pass through the semi-permeable membrane and are discharged with the concentrate.

One of the key benefits of reverse osmosis equipment is the high filtration precision. The pore size of the reverse osmosis membrane is only 0.0001 micrometers, which is significantly smaller than the pore size of other filtration methods like a typical PP cotton filter cartridge (5 micrometers) or ultrafiltration membrane (0.01 micrometers). Even bacteria and heavy metal ions have a pore size of 0.001 micrometers which means that the reverse osmosis equipment can effectively remove impurities, bacteria, and other substances from water.

Another advantage of reverse osmosis equipment is its large water production capacity. Depending on the requirements, the water production capacity can range from 1 to 100 tons. The minimum water production capacity for household use is 7.8 liters per treatment. The equipment can be configured to produce 0.5 tons, 1 ton, 2 tons, 5 tons, 10 tons, 50 tons, or 100 tons depending on specific needs.

Additionally, reverse osmosis equipment is equipped with intelligent control systems. Fully automatic control valves can be set based on flow rate or time, and the filter media of the equipment can be self-cleaned online. This means there is no need for manual monitoring, making it convenient, fast, and labor-saving.

Reverse osmosis equipment has a long service life due to the use of high-quality materials. The use of quartz sand, activated carbon, scale inhibitors, fine filtration, and five-stage reverse osmosis filtration process can extend the lifespan of the equipment, making it a cost-effective solution for many consumers.

Lastly, reverse osmosis equipment has a high water recovery rate, achieving up to 75% recovery rate. This means that it produces less wastewater than other methods, making it an eco-friendly choice for those who are environmentally conscious.

Purified and Ultrapure Water in Industries

Purified water and ultrapure water are essential in industries such as electronics, industrial, pharmaceutical, and food. These industries require clean and high-quality water for their production processes and end products. The preparation of purified water and ultrapure water is crucial to ensure the safety and quality of the products.

Purification and Preparation of Process Water in Textile and Chemical Industries

The textile and chemical industries require process water and chemical circulating water that must be purified to ensure the quality of their products. Additionally, chemical products can only be manufactured with high-quality water. The preparation and purification of water are necessary in these industries to maintain optimal production processes and to ensure that their products meet the necessary standards.

The food and beverage industry requires clean and purified water to ensure the safety and quality of their products. Water is used in various processes such as making beverages, beer, liquor, health products, and more. Drinking purified water is also essential for public health. The careful purification and preparation of water are necessary to ensure that the water is safe and meets the necessary standards.

Concentrating and recovering useful substances in industrial production can greatly improve efficiency and reduce waste. Clean water is often used in these processes to ensure optimal results. Purification and preparation of water play a vital role in useful substance concentration and recovery.

In the power industry, water is used in high-pressure boiler feedwater, boiler feedwater for thermal power boilers, and low-pressure boiler power systems in plants and mines. Pretreatment of this water is vital to ensure safe, efficient, and reliable operation of these systems. The purification and preparation of water are necessary to maintain the optimal operation of these systems.

Desalination and desalting of brackish water and seawater can provide clean and high-quality water for various industries such as electronics, pharmaceutical, and food. Islands, ships, offshore drilling platforms, and brackish water areas can also benefit from these processes to obtain safe and usable water. The careful purification and preparation of water are necessary for effective desalination and desalting.

Primary desalination equipment plays a vital role in high-purity water production, especially in pure water systems. These systems require highly purified water that meets very strict standards. The careful purification and preparation of water are necessary to ensure that the primary desalination equipment produces high-purity water.

Various enterprises and institutions with a large number of people, including communities, real estate properties, schools, factories, hospitals, tea houses, hotels, beauty salons, canteens, etc., require purified water for various uses. For example, bottled water, mineral water, and other packaged water are commonly used in these institutions. The careful purification and preparation of water are necessary for safe and high-quality water for these entities.

The electronics industry requires clean and high-quality water for various processes such as rinsing water for integrated circuits, silicon wafers, display tubes, and other electronic components. The careful purification and preparation of water are necessary to ensure that the quality of the water meets the necessary standards for these processes.

The pharmaceutical industry requires clean and high-quality water for various processes such as large-volume infusion, injections, tablets, biochemical products, equipment cleaning, and more. The careful purification and preparation of water are necessary to ensure that the water is safe, high-quality, and meets the necessary standards for these processes.

Desalination of seawater and brackish water is necessary for various entities such as islands, ships, offshore drilling platforms, and brackish water areas. The careful purification and preparation of water are necessary for effective desalination, which can provide safe and usable water for these entities.

Ultra-pure water is necessary for various processes such as automotive, household appliance painting, coated glass, cosmetics, fine chemicals, and more. These processes require water that meets very strict standards for cleanliness and purity. The careful purification and preparation of water are necessary to ensure that the water is suitable for these processes.
