Membrane deamination is an advanced water treatment technology designed specifically for the efficient removal of ammonia nitrogen from water.
Membrane deamination is an advanced water treatment technology designed specifically for the efficient removal of ammonia nitrogen from water. Its core mechanism is to use the unique properties of membrane materials to physically separate ammonia nitrogen. The following is a detailed introduction to the core of membrane deamination membrane for ammonia nitrogen removal:
Material selection of deamination membrane:
Deamination membranes usually use polytetrafluoroethylene (PTFE) as the main membrane material. PTFE has excellent corrosion resistance and hydrophobicity, and can maintain stable performance under extreme acid and alkali environments and high temperature conditions.
Structure of deamination membrane:
The deamination membrane is composed of hollow fiber membrane filaments, which have extremely small inner diameters and huge specific surface areas, providing efficient material transfer power.
Working principle of Ammonia Removal Membrane:
During the deamination process, the pH value of the wastewater is adjusted to an alkaline state, which promotes the conversion of ammonia nitrogen into gaseous NH3. Then, the gaseous NH3 passes through the micropores of the membrane, interacts with the acidic absorption liquid flowing outside and reacts chemically, thereby achieving efficient removal of ammonia nitrogen.
Advantages of Ammonia Removal Membrane:
Compared with traditional stripping methods, deamination membrane technology has the characteristics of low energy consumption, no secondary pollution, simple operation, and low initial investment. In addition, this technology can achieve deep removal of ammonia nitrogen, with the lowest reaching below 100ppm.
Application scope of Ammonia Removal Membrane:
Ammonia removal membrane technology has been widely used in medicine, chemical industry, metallurgy, fertilizer, landfill leachate, electronic integrated circuit manufacturing and other industries, especially in the treatment of high-concentration ammonia nitrogen wastewater.
