A membrane can "eat dry and squeeze" seawater to achieve seawater desalination; a membrane can recycle industrial wastewater to achieve huge economic and social benefits. The author walked into the pilot plant of Binhai Tianwei Membrane Technology Co., Ltd. The general manager of the company, Lian Wenyu, took a piece of white cardboard-like ion exchange membrane to show the author the magical transformation of seawater into fresh water.
Homogeneous ion exchange membrane is a typical marine new material, the introduction of marine element bromine, by controlling the reaction conditions, can achieve the precise control of bromination position and degree of bromination, promote the separation of sodium ions and chloride ions in seawater, so as to achieve the effect of seawater desalination.
Chief engineer Rong Qiang called this process electrodialysis seawater desalination. In his eyes, this is the treasure, "through this technology, compared with the traditional process, the energy consumption will be reduced by about half, the efficiency will be increased by 10%, and 0.5 tons of fresh water per ton of marine products."
In Tianwei Film Company, there are many high-performance series of charged membrane materials and their application key technologies. It can not only desalinate seawater, but also treat high-acid and high-alkali wastewater. Through the magical effect of "Tianwei membrane", the acid or alkali recovery rate in wastewater reaches 90%. If 10 tons of acid were used for production in the past, but now 1 ton is enough, the input cost will be reduced, the environmental protection problem will be solved, the benefits of the enterprise will come up, and one "input account" will become "two benefit accounts".
In the current increasingly severe environmental protection situation, the application of "Tianwei Film" has turned the environmental protection management of burning money into a benefit generator.
