Chlorination eliminator is a kind of equipment used to purify water quality and an important part of water treatment system. It mainly removes chlorine content in water through filtration and adsorption, so as to improve water quality. The filtration principle and working mechanism of chlorination eliminator will be introduced in detail below.
Filtering principle
The filtration principle of chlorination eliminator is mainly to remove impurities and chlorides in water through filter material. The filter material is usually composed of activated carbon and other adsorbents, which have strong adsorption capacity and can effectively remove organics and chlorides in water.
In the process of water treatment, the water is first pretreated to remove large particles and suspended solids. Then enter the filter material layer of chlorination eliminator. The filter material layer has high porosity and adsorption performance, which can absorb organic and chemical substances in water, especially chlorides.
The activated carbon in the filter material has a large number of pore structures, which can absorb dissolved organics and chlorides in water. At the same time, activated carbon can also remove the odor and color of water, and improve the taste and quality of water.
Other adsorbents in the filter material layer, such as ion exchange resin and silica gel, can absorb heavy metal ions and other harmful chemicals in the water. These adsorbents have strong affinity and can form chemical bonds with ions in water and fix them in the filter material layer to purify impurities in water.
Working mechanism
The working mechanism of chlorination eliminator is mainly divided into two steps: adsorption and regeneration.
(1) Adsorption: when the water passes through the filter material layer, the activated carbon and adsorbent in the filter material begin to adsorb the organics and chlorides in the water. These substances are fixed in the pores of the filter material layer to purify the water quality.
Adsorption is a process in which a substance is adsorbed from a molecule in a gas, liquid or solution to the surface of another substance. In the chlorination eliminator, the surface of activated carbon and adsorbent has many pores and active sites, which can absorb dissolved organics and chlorides in water.
(2) Regeneration: as time goes on, the filter material layer gradually becomes saturated, and it is unable to continue to absorb new impurities. At this time, it is necessary to regenerate the filter material to restore the adsorption capacity of the filter material.
The regeneration of filter material can be carried out by many methods, such as desorption, pyrolysis, aeration, etc. Among them, desorption is the most commonly used regeneration method. It realizes the regeneration of filter material by reversely passing a certain concentration of reverse solution (such as salt water and acid solution) through the filter material layer to dissolve and flush the impurities adsorbed in the filter material.
The frequency and method of regeneration can be adjusted according to the water quality and the use of filter materials to obtain the best purification effect.
During the working process of chlorination disinfector, pay attention to the regular replacement of filter material and cleaning of filter material layer. The renewal of filter material can ensure the long-term stable operation of equipment and improve the treatment effect of water quality.
To sum up, the chlorination eliminator removes organics and chlorides in water through the adsorption of filter materials, thus improving the water quality. Through reasonable use and maintenance of chlorination disinfector, the water quality can be effectively purified to ensure the safety of water supply.
