Application and maintenance of ultrafiltration membrane for automatic reverse osmosis pure water treatment equipment? Author: Social water pollution is very serious now, people are required for water has improved a lot, automatic reverse osmosis membrane water treatment equipment selection also becomes particularly important: in general, is a membrane A microporous filter membrane with the same pore size specifications and a rated pore size range of 0.01 microns or less Most of them are used in pure water treatment, separation, concentration, purification of biological products, pharmaceutical products and food industry. Today, technicians mainly tell you about the maintenance methods and application methods of ultrafiltration membranes for automatic reverse osmosis pure water treatment equipment. When there is a pressure difference on both sides of the ultrafiltration membrane, when the tap water flows through the membrane surface, there are many tiny pores densely distributed on the surface of the ultrafiltration membrane (about 6 billion are distributed on the wall of the ultrafiltration membrane per meter long). 0.01 micron pores) only allow water molecules and small molecular substances (beneficial minerals and trace elements) to pass through, and substances with a volume larger than the diameter of the pores (bacteria, colloids, rust, suspended matter, sediment, and macromolecular organic matter) Are larger than bacteria) are intercepted, so as to achieve the effect of purifying the tap water. The cleaning steps of the ultrafiltration membrane of the automatic reverse osmosis pure water treatment equipment: 1. First, rinse the entire ultrafiltration (which can retain macromolecular substances and proteins between 0.002-0.1 microns) with clean water, and the water temperature adopts reverse osmosis (with the help of half Membrane separation technology through membrane) The higher temperature that the membrane module can withstand 2. Choose a suitable cleaning agent to clean the water treatment equipment: the list of drinking water, the cleaning agent can contain complexing agents such as EDTA or sodium hexametaphosphate . 3. Rinse with clean water to remove the cleaning agent. 4. Check the water permeability of the membrane under the specified conditions. If it fails to reach the expected value, repeat the steps. 5. Soak and disinfect with 0.5% formaldehyde aqueous solution (refers to the method of killing pathogenic microorganisms, but not necessarily killing bacterial spores) and storing. The impact of improper operation of the fully automatic reverse osmosis pure water treatment equipment on the ultrafiltration membrane: 1. For pure water treatment, most of the damage to the ultrafiltration membrane element occurs in the initial stage of element filling and operation. Because the equipment is a more rigorous product, it is prone to mechanical damage. 2. Incorrect design or misoperation of the automatic reverse osmosis pure water treatment equipment will cause the membrane to be damaged and cause the performance of the ultrafiltration membrane to decrease. The performance deterioration caused by such damage is difficult to recover. 3. Failures occurred during the operation of the ultrafiltration membrane: This is generally caused by the wrong operation status, which will cause the production water flow to drop, and it can be restored as long as the correct operation status is reset. Through the above introduction, you must have understood the cleaning and maintenance methods of the ultrafiltration membrane of the fully automatic reverse osmosis pure water treatment equipment. If the cleaning is not in place, it will not only reduce the life of the equipment, but also affect the water quality.
