Flux recovery and maintenance method for water purification filtering element

Abstract

The invention discloses a flux recovery and maintenance method for a water purification filtering element. According to the characteristics of a hollow fiber ultrafiltration membrane made of a polyvinyl chloride material, primary physical cleaning is performed before delivery; after the water purification filtering element leaves a factory and is used, primary physical cleaning and chemical cleaning are performed respectively every three months; on the premise of guaranteeing the normal working efficiency, impurities caused in a filtering element working process can be timely removed, and the filtering element can be timely protected; substances such as microorganism germs can be also timely removed through regular chemical maintenance, and therefore, the water quality standard is guaranteed, and meanwhile, effects of timely recovering and protecting the flux of the filtering element are achieved; the expenses on frequently replacement of the filtering element by a user are saved; the flux recovery and maintenance method is environmentally friendly, economical and high in practical value.

Description

technical field [0001] The invention relates to the maintenance of a water purification filter element for water treatment, in particular to a flux restoration and maintenance method of the water purification filter element. Background technique [0002] Water quality is a major focus of people's life in society. At present, more and more families in China and some foreign countries choose water purification equipment for household water purification treatment. Most water purifiers use filter element + filter material for purification. In the treatment of water, during the long-term use of the filter element, on the one hand, due to the performance of the ultrafiltration membrane inside the filter element itself, the adsorption is gradually saturated; on the other hand, pollution often occurs in the water filtration and purification system. The first category is the filter residue One is the pollution of microorganisms in the water, and the other is the pollution caused by t...

Problems solved by technology

The long-term accumulation of these pollutions not only reduces the efficiency and flux of the filter element, but also makes it difficult to achieve the quality of the water body.

In order to save costs, some families often do not take the initiative to replace the filter element, or postpone the replacement, which is not only not conducive to the water purification effect of the water purifier, but also causes harm to human health.
