SUEZ AG-365 reverse osmosis membranes have a desalination rate of up to 98%, which can effectively remove dissolved salts from water and provide pure permeate water. This kind of membrane adopts special materials and technologies, has good anti-pollution performance, can effectively resist the adhesion and clogging of pollutants such as suspended solids, colloidal substances and microorganisms in water, and adapts to the needs of water treatment under various temperature conditions. Below, the blue film water treatment will introduce to you how to deal with its blockage.
Blockages can be dealt with in several ways:
1.Backwashing: Backwashing is one of the most commonly used methods to treat blockages in SUEZ AG-365 reverse osmosis membranes. In the backwashing process, the inlet and outlet ends of the reverse osmosis membrane are reversely connected, and the pollutants attached to the membrane surface are washed down by the inlet pressure. Backwashing can be carried out with clean water, pressurized water or gas, and the appropriate backwashing method can be selected according to the blockage situation and equipment requirements.
2.Chemical cleaning: Chemical cleaning methods can be used when backwashing fails to remove contaminants from the membrane surface. Chemical cleaning agents mainly include acids, alkalis, surfactants, etc., and the appropriate cleaning agent can be selected according to the membrane material and the type of contaminant. In the chemical cleaning process, the cleaning agent is added to the inlet end of the reverse osmosis membrane, and the contaminants on the surface of the membrane are removed by circulating cleaning.
3.Physical cleaning: Physical cleaning methods mainly include ultrasonic cleaning, high-pressure water jet cleaning, etc. These methods strip contaminants from the membrane surface by physical force, restoring the water flux and desalination of the membrane. During the physical cleaning process, the cleaning intensity should be controlled to avoid damage to the membrane.
4.Bio-cleaning: Bio-cleaning is the use of microbial metabolites and biofilms to remove contaminants from membrane surfaces. In the process of biological cleaning, a layer of biofilm can be formed on the surface of the reverse osmosis membrane, and the pollutants on the surface of the membrane can be decomposed and removed through the metabolic action of microorganisms. The bio-cleaning method is suitable for dealing with membrane clogging caused by microbial contamination.
5.Replacement of membrane elements: When the SUEZ AG-365 reverse osmosis membrane is severely clogged and cannot be restored by cleaning methods, the membrane element needs to be replaced. When replacing the membrane element, it is necessary to choose the same membrane material and specification as the original equipment to ensure the stability of the water treatment effect.
In short, when dealing with the problem of reverse osmosis membrane blockage, one or more methods can be used to deal with it according to the actual situation. At the same time, it is necessary to strengthen daily maintenance and operation management to prevent the occurrence of membrane blockage.
