    High temperature resistant membrane

    Membrane technology has been successfully applied to various industries such as water treatment, biology, medicine, food, beverage, chemical industry, petroleum and petrochemical industry because of its unique selective filtration characteristics. The normal temperature of the membrane core is within 45℃, the high temperature resistant membrane core provided by GUOCHU Technology can meet the requirement of high temperature condition filtration under different filtering precision of the user: Micro filter level core tolerance temperature exceeds 100℃; the filtration temperature of ultrafiltration, nanofiltration and reverse osmosis membrane can be effectively filtered within 90℃.

    High temperature resistant steam disinfectant micro-filtration membrane:

    Inorganic micro-filtration membrane (MF) is an asymmetric membrane formed by a special process of inorganic materials. The membrane of inorganic membrane is closely packed with micropores. Under pressure, the raw material flows in the membrane tube or outside the membrane. Small molecules pass through the membrane, and macromolecules are trapped by membrane, so as to achieve separation, concentration, purification and environmental protection. The inorganic membrane has high separation efficiency, stable effect, good chemical stability, acid and alkali resistance, organic solvent resistance, bacteria, high temperature resistance, anti pollution, high mechanical strength, good regeneration performance, simple separation process, low energy consumption, easy operation and maintenance, long service life and many other advantages, it has been successfully applied to many fields, such as food, beverage, Chinese medicine, plant deep processing, biological medicine, fermentation, fine chemical industry and so on. It can be used for separation, clarification, purification, concentration, desiccation, desalting and so on in technique process.

    Inorganic microfiltration membrane can withstand high temperatures above 100℃, it is especially suitable for high temperature gas filter, high temperature liquid clarification and filtration, as well as the application fields requiring high temperature steam disinfection.

    High temperature hot water disinfection type ultrafiltration, nanofiltration, reverse osmosis membrane:

    The constant operating temperature of an ordinary organic membrane element must be less than 50°C, if the temperature film exceeds this temperature, it will soon lose its normal performance. Hot water disinfectant membrane components can withstand periodic 90°C hot water cleaning and disinfection, it is used to replace the traditional chemical disinfection membrane system, and achieve continuous operation under conditions ≤50°C. In some specific fields, for example, biological insecticides cannot be used in pharmaceutical and Bioengineering, and high temperature hot water disinfection can be used.

    In 1865, Pasteur found that hot water could kill bacteria or microbes to a safe level. This sterilization method is called Pasteur heating sterilization, and its basic principle is: Hot water passes heat to the microbe, causing the protein chain degeneration and condensation in the microorganism, which causes the microorganism to lose its activity. In Europe and America, with the continuous improvement of the production standard of pharmaceutical industry, especially with the stricter requirement of USP, the hot water disinfection water treatment system is being used widely.

    The resistance of microorganisms to heat in asexual reproduction
    Temperature tolerance80℃80℃60~70℃60℃
    Tolerance time5~10 minutes30 minute10 minute30 minute

    The above data are the minimum theoretical parameters for thermal sterilization of asexual reproduction. In order to increase the effectiveness of thermal disinfection, the temperature and time of thermal disinfection should be higher than the theoretical parameters.

    The hot water disinfectant membrane element is designed with advanced membrane structure, and it can maintain excellent performance even under extreme operating conditions. At the same time, the membrane core can also reach the USDA standard and 3A standard of dairy industry.

    Application of high temperature resistant membrane:

    When the reverse osmosis membrane contains bacteria and other active organisms, we must take measures to kill them to prevent biofouling on the membrane surface and the resulting loss of membrane performance. The traditional disinfection method is chemical method, but the chemical method has the disadvantages of low efficiency, high cost and toxic residue, the hot water sterilizing reverse osmosis membrane (temperature resistance to 90℃) is used in hot water disinfection, which can completely replace the traditional chemical disinfection method. High temperature resistant membrane can also be used in evaporator condensate water treatment, medicine injection production and so on.
