Description
Technical Field
The utility model relates to the technical field of water purifiers, in particular to a back flushing tail end water purifier.
Background
In the existing water purification treatment method, membrane pollution phenomenon is likely to occur along with the increase of operation time in the use process of the membrane water treatment technology, so that the performances of membrane permeation flux, rejection rate and the like are changed, the service life is shortened, and the practical application of the membrane separation technology is greatly hindered. Therefore, it is necessary to take corresponding cleaning measures and control measures to partially or completely recover the film properties.
In the current filtration system of the household water purifier, the main reason for membrane pollution is adsorption pollution on the surface of the membrane. Membrane adsorption pollution refers to the phenomenon that membrane pore diameters become smaller or are blocked due to adsorption and deposition on the membrane surface or in membrane pores caused by physical, chemical or mechanical action of microparticles, colloid particles and solute macromolecules in a treatment material and the membrane, so that membrane flux and separation characteristics of the membrane are changed. The contamination layer formed by the deposition of the components in the feed solution on the membrane surface will increase the resistance of the membrane process, which may be much greater than the resistance of the membrane itself; deposition of the components in the membrane pores will result in a reduction or even clogging of the membrane pores.
At present, after a household water purifier is used for a period of time, a regular direct abandoned filter element is adopted, and a new filter element is replaced to maintain the filtering performance of the water purifier, so that a household membrane filter element component becomes a consumable, and a great amount of material resources and financial resources are wasted and lost.
