Light, soft and delicate, a piece of "plastic film" like an open disc seems to have no weight in the hand, but as the latest fist product of Chengdu Meifute Environmental Protection Co., Ltd. (hereinafter referred to as Meifute), the core subsidiary of Meifute Membrane Technology Co., Ltd., it has a decisive "weight" in the world.
In the Meifute exhibition hall located in Huaizhou New City Energy Conservation and Environmental Protection Industrial Park, Jinjin closely watched and touched this "plastic film" - special disc tube reverse osmosis membrane, recently, it and other star products of Meifute appeared at IE Expo China, Asia's flagship environmental protection exhibition, becoming another famous card of "Jintang Manufacturing".
"As a high-tech enterprise, Meifute Membrane Technology Co., Ltd. is mainly committed to the research and development of special membranes. At present, it is the only enterprise in China that has the R&D and production capacity of a full range of special membrane products such as ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO). Pan Yang, manager of the membrane material R&D department of Meifute R&D center, led Jinjin to visit the company's exhibition hall.
"The disc tube reverse osmosis membrane module is our very competitive core product, and one of its advantages is this reverse osmosis diaphragm, which is currently the world's largest operating pressure of a reverse osmosis diaphragm, with a maximum operating pressure of 160 kilograms. Pan Yang gently picked up the encapsulated diaphragm and explained to Jin Jin in detail the leading edge of the diaphragm.
Pan Yang said that any membrane product has the concept of osmotic pressure, and when it is applied to sewage treatment, the greater the osmotic pressure overcome by the membrane, the higher the concentration of sewage can be achieved. "Our membrane can achieve higher multiples concentration when it is suitable for industrial wastewater treatment and reclaimed water reuse with zero discharge, which greatly reduces the equipment investment and operating costs of the MVR evaporation process section when the wastewater is discharged with zero discharge. So far, the diaphragm in my hand can be described as the world's leading, and there is another 'global leading' is the process by which we make this diaphragm. ”
In the water treatment separation membrane industry where Meifute is located, any polymer diaphragm must also have an important indicator - compression resistance. In Pan Yang's words, it is "the water conductivity of the plastic diaphragm hole under high pressure". "In fact, everyone knows that the diaphragm is plastic, and its cross-section actually has pores, which mainly play a function of water conduction and circulation. After the membrane is compacted at high pressure, the pore diameter flow channel may be collapsed, which greatly attenuates its flux and greatly reduces its water conductivity. Therefore, how to improve the compression density performance of the membrane, in fact, is a very big technical barrier, but our company has broken through the technical barriers of the product by strengthening scientific and technological research, at the beginning of February this year, this 160 kg ultra-high pressure resistant reverse osmosis diaphragm by Jian Xigao academician and other experts appraisal, has been in the international leading position. Pan Yang said.
It is understood that at present, the reverse osmosis membrane of Meifute special disc tube has been successfully applied to electroplating, printing and dyeing, chemical, pharmaceutical and other industries, and has become an "industry leader" in the market segment of the disc tube membrane, and has been applied in the domestic and foreign markets.
In the next step, Meifute will continue to promote the integration of technology research and development and industrial application, release the vitality of enterprise development, accelerate the transformation process of scientific and technological achievements, continuously improve the core competitiveness of the market, add new assistance to the green and low-carbon industry of Huaizhou New Town, and add new connotation to the "Jintang" products, while comprehensively promoting the healthy and sustainable development of the zero-emission industry of special membranes, and contributing more to social and economic development.
