For the desalination of seawater and brackish water, Zhongmaide obtained the desired purified water by improving the traditional seawater desalination process, and at the same time realized the concentrated water and salt recovery technology (zero waste water), and reused the concentrated water for salt fields and chemical agents. and other fields. The ZSP series high-pressure pump, SWRO membrane with high desalination rate and the energy recovery system of the patented technology of Zhongmaide are used independently developed and produced by Zhongmaide. The device structure is made of corrosion-resistant dual-phase steel, which ensures the life of the system and the stability of water production. sex. Sinomed's desalination technology can be designed according to the different needs of cities, ships and industries to create an overall modular/container/solar/marine desalination system. The cost of water production is far lower than that of commercial water and external water. Reserve costs, etc. Tailor-made energy-saving and emission-reduction systems for coastal cities, islands, industries, and other fields, countries with limited fresh water, and offshore operating agencies. Zhongmaide seawater desalination equipment adopts reverse osmosis membrane separation technology, and is equipped with water treatment processes such as double-stage filtration, double-stage reverse osmosis, and post-mineralization, and is equipped with an energy recovery system, which can filter out particulate impurities, harmful ions and other substances in the water. To achieve desalination of seawater, direct drinking water. Sinomed's seawater desalination technology is to realize the open-source increment of seawater resource utilization, increase the total amount of fresh water, and is not affected by time, space and climate, and can ensure stable water supply such as drinking water for coastal residents and industrial boiler make-up water. It has the characteristics of small size, high degree of automation, high desalination efficiency, convenient operation, high energy recovery rate, stable effluent quality, high salt and corrosion resistance, high equipment earthquake resistance level, convenient transportation, etc. The effluent standard meets the national drinking water standard＜ GB5749-2006>. Fixed water supply or mobile water supply can be provided according to different locations and water use methods.
