For many years, Dow has been committed to improving FILMTEC reverse osmosis membrane technology. Dow RO reverse osmosis membrane elements feature a stable high desalination rate, are easy to clean, and come in a complete range of models, suitable for various water treatment projects with different water qualities and quantities. Several commonly used Dow RO reverse osmosis membranes nowadays, such as BW30-400, BW30-365, BW30-400IG, BW30-365IG... Wait a moment. The application of Dow membrane products in the United States: Dow membranes are widely used in fields such as power, petrochemical, steel, electronics, medicine, beverages, municipal and environmental protection. They play a significant role in seawater and brackish water desalination, boiler feed water, industrial pure water and electronic-grade ultra-pure water preparation, drinking pure water production, wastewater treatment and special separation processes. The usage conditions of Dow membrane elements in the United States: Dow FILMTEC membrane elements come in different models, each designed for different applications and usage conditions: XLE ultra-low energy consumption (pressur
Details >Softening water equipment removes heavy metals from water, turning hard water into soft water. Drinking soft water treated by softening water equipment tastes good and has no peculiar smell. Using soft water can save money. Because soft water does not form scale and does not cause rust, it will reduce the amount of soap and laundry detergent used in household washing, and decrease the occurrence of chronic diseases such as heart, brain and kidney problems. Meanwhile, soft water can effectively inhibit. When a skin injury or similar accident occurs, first wash the affected area with soft water, then soak absorbent cotton, gauze, towel, etc. in soft water and gently rub the affected area. This can quickly heal the wound and make the caused swelling disappear immediately. This is because soft water has the function of regenerating cell tissues.
Details >The editor of Yuanlai Jun learned that a resident reported that when making soy milk with well water at home, the result was not soy milk but a mixture of layered water and some insoluble substances. However, the same beans could be made into soy milk with the tap water from a neighbor's house. In response to this strange inquiry, the municipal prevention and control department conducted a water quality test on the well water in the village, thus revealing the mystery that well water could not be used to make soy milk. Does everyone know what the reason is? According to the test results, the total hardness and nitrate nitrogen of the water quality seriously exceeded the standard. Among them, the total hardness was 720mg/L, which exceeded the national standard of 270mg/L. The test result of nitrate nitrogen was 96mg/L, which was nearly five times higher than the national standard. According to relevant analysis by the municipal disease control center, the reason why this water cannot be used to make soy milk might be related to the excessively high hardness of the water.
Details >Things You Don't Know about water treatment equipment
Nowadays, people are paying more and more attention to water health issues, which has led to the development of water treatment equipment. There are many types of water treatment equipment, such as mineral water equipment and purified water equipment, etc. The hardness and price of water treated by different water treatment equipment also vary. Simply put, "water treatment" is the process of removing some harmful substances from water that are not needed for production and daily life through physical, chemical and biological means. It is a process of water quality adjustment, including sedimentation, filtration, coagulation, flocculation, corrosion inhibition and scale prevention, carried out for specific uses. As social production and life are closely related to water. Therefore, the application scope involved in the water treatment field is extremely wide, forming a huge industrial application.
Details >"Beijing fully automatic water softening?" Beijing drinking water filter?
Water softeners mainly address the problem of scale caused by hard water. Therefore, in the United States where water quality is relatively hard, household water softeners have become quite common. Household water softeners have entered the market, mainly targeting the regions of North China and Southeast China where water quality is relatively hard, and are still in their infancy. At present, the terminal sales of the products are mainly concentrated in Beijing and Shanghai. Why do we need to soften water? Natural water can be divided into two types: hard water and soft water. Water containing a relatively large amount of calcium and magnesium ions (inorganic minerals) is called hard water. Conversely, it is called soft water. If the hardness of water is caused by the presence of sodium carbonate or magnesium bicarbonate, such water is called inherently hard water. If the hardness of water is caused by sulfates or chlorides containing calcium and magnesium, such water is called eternal hard water. Simply put, water with a calcium carbonate content of less than 10 milligrams per liter is considered high-standard soft water. You know

Yuan LaiEDIThe ultra-pure water equipment uses electro-deionization technology.EDIElectrodeionization is a water purification method that combines the dual advantages of electrodialysis and ion exchange. It does not require acid-base chemical regeneration and can continuously and stably prepare high-purity ultrapure water. Under the action of a direct current electric field, ion separation in water is completed. At the same time, water is electrolyzed to generate hydrogen ions and hydroxide ions, achieving automatic regeneration of the resin without the need to stop the machine for manual regeneration. The pre-treatment combined with reverse osmosis can prevent oxidized substances from damaging the resin, ensuring stable effluent quality and widely meeting the high-standard water usage requirements of various industries.
The non-negative pressure water supply equipment can be directly connected to the municipal water supply network, making full use of the residual pressure of the original network for superimposed water supply. Fully enclosed operation does not require the construction of a domestic water tank, eliminating secondary pollution. Intelligent variable frequency voltage stabilization, energy-saving, quiet and easy installation, it is the preferred equipment for secondary water supply in high-rise residential buildings and commercial buildings.
Constant pressure water supply equipment is widely used in central air conditioning, floor heating, industrial closed-loop water circulation, and boiler systems. It integrates automatic pressure stabilization, automatic water replenishment, automatic exhaust, pressure relief and buffering functions. It stabilizes the pressure in the pipeline network, eliminates abnormal sounds caused by air blockage, and prevents damage from negative pressure and water shortage in the pipeline. It is an essential supporting equipment for HVAC and circulating water systems.
