Pure water equipment can produce high-quality pure water to ensure the safety of drinking water for the public, but do you know why pure water equipment is so efficient? That's because its reverse osmosis membrane is working, and its gradual decay after long-term use is a normal phenomenon, but some of it is caused by improper membrane performance. Below, the editor will explain to you the reasons that cause damage to the reverse osmosis membrane of purified water equipment. Let's take a look together.

Firstly, if the reverse osmosis membrane of pure water production equipment is not properly cleaned or improperly cleaned, its performance will be greatly damaged. During equipment operation, in addition to some normal performance degradation, it will also be severely polluted by microorganisms, organic matter, and chemical pollutants. According to research, the symptoms of pollution change with the length of time spent. Taking calcium carbonate stains as an example, when the pollution time is one week, the desalination rate will rapidly decrease, and the pressure difference will gradually increase, with little impact on the water production rate. At this point, citric acid can be chosen. Cleaning. If the pollution period is extended by one year, it will cause serious harm to the water production rate and greatly increase the salt flow rate.

Secondly, it is necessary to comprehensively determine the type of pollution based on various factors such as the source water body, pollution indicators, and equipment performance. When the microfilter in the pre-treatment system rapidly blocks or the pressure difference rapidly increases, colloidal contamination may occur. When the total number of bacteria passing through water and concentrated water in the system is relatively high, it is likely to be contaminated by microorganisms, which is generally caused by inadequate maintenance and disinfection or incorrect operations.

Reverse osmosis membrane is a key water treatment accessory for promoting pure water equipment, and is an artificial semi permeable membrane made of biomimetic semi permeable membranes with certain characteristics. Generally made of polymer materials. Such as cellulose acetate film, aromatic polyamide film, aromatic polyamide film, etc. The diameter of surface pores is usually between 0.5 and 10nm, and the permeability is related to the chemical structure of the membrane itself. Some polymer materials have good repulsion to salts, and water cannot be well treated. Some polymer materials have more hydrophilic groups in their chemical structure, so water is relatively fast. Therefore, a satisfactory reverse osmosis membrane should have an appropriate infiltration rate or desalination rate.
