Zhu Ronghui, founder of Beijing Saimei Energy Technology Co., Ltd., said that seawater desalination has two methods: thermal method and membrane method. The seawater passes through air flotation, ultrafiltration membrane, reverse osmosis and other processes to remove seawater salts, suspended solids, bacteria, etc., and finally meets the national drinking water standard. This process is called "membrane method".
According to Zhu Ronghui, in the current global desalination market share, the membrane method accounts for about 65%, and the thermal method accounts for about 30%. Among them, the membrane seawater desalination technology is relatively low in cost.
The key technology of “membrane method†desalination has been monopolized by a few countries. Zhu Ronghui led his team, after more than two years, developed a unique international device for “integration of seawater desalination and pressure recoveryâ€. In April of this year, the technology applied for a national patent.
It is understood that after the establishment of the Zhongguancun New Energy Seawater Desalination Industry Technology Innovation Alliance, the Zhongguancun New Energy Seawater Desalination ( Membrane Method) Demonstration Project was officially launched: in the Caofeidian Nissan 50,000-ton seawater desalination plant that has been built by Beijing Enterprises Water; Demonstration project of seawater desalination membrane method.
The first phase of the project was officially launched in August 2012 and was organized and implemented by Sino Water. The key technical equipment includes ultrafiltration membranes and components, reverse osmosis membranes and components supplied by Sino Water, developed by Saimei The seawater desalination pressure and energy recovery integrated device, the seawater and fresh water storage equipment provided by Beijing Taining Science & Technology Co., Ltd.
The second phase of the project began in September 2013 and was completed in August 2014. The self-developed seawater desalination and pressure recovery and energy recovery integrated device system was optimized on the basis of the first stage. The project uses solar power generation combined with low-valley electricity as energy input to reduce the operating cost of the system while reducing operating costs. The reduction of unit product cost is conducive to the demonstration role and industrialization of the project. The domestic ultrafiltration membrane further verified its reliability and economy on the basis of continuous operation.
After 2 years of construction, through the equipment debugging, system improvement, program optimization, control parameter adjustment, achieved the ideal experimental and engineering results. Provide technical support for the design and construction of domestically produced desalination systems; provide experimental and engineering basis for the calculation of investment costs and operating costs of localized desalination systems.
The person in charge of the Zhongguancun Management Committee said that the smooth implementation of the project is of great significance, which not only reduces the cost of desalination, but also provides a total solution for the “localization†and “Beijing production†in the large-scale desalination project in the future. .
The Zhongguancun New Energy Desalination Key Technical Equipment Demonstration Project (membrane method) has recently passed the acceptance of the expert group to form a complete set of seawater desalination technology with independent intellectual property rights. The project broke the foreign monopoly and reduced the current seawater desalination water cost by more than 10%.
