A method and system for judging the life of a filter element through a water quality detector

Abstract

The present invention provides a method for judging the life of a filter element through a water quality detector. value, and the total flow value and flow velocity value collected by the flowmeter after filtration; step S2, according to the TOC value, COD value, UV254 value, total flow value and flow velocity value to determine the filter element life. The present invention also provides a system corresponding to the method. The advantages of the present invention are: by using TOC value, COD value, UV254 value, total flow value, flow velocity value and TDS value to judge the combination of multiple values, it can realize more accurate judgment of the actual service life of the filter element, and provide the replacement of the filter element. reliable judgment.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to a method and a system for judging the life of a filter element through a water quality detector. Background technique [0002] With the continuous improvement of living standards, people are more and more concerned about the quality of daily drinking water, and various water purification equipment are constantly entering people's field of vision. [0003] The filter element is a core component of the water purification equipment. Since the filter element has the functions of filtering and purifying, when the tap water flows through the filter element, the tap water can be filtered and purified. At present, after a period of use of the filter element used in water purification equipment, various impurities, bacteria, etc. will be attached to the filter element, which will cause the filtration effect to deteriorate. Therefore, in order to ensure the quality of drinking w...

Problems solved by technology

At present, after a period of use of the filter element used in water purification equipment, various impurities, bacteria, etc. will be attached to the filter element, which will cause the filtration effect to deteriorate. Therefore, in order to ensure the quality of drinking water, after a period of use. Filter element needs to be replaced

In the prior art, when the filter element is replaced, the filter element is usually replaced regularly. However, this regular replacement method has the following defects in the actual use process: the actual service life of the filter element cannot be judged, resulting in premature replacement. Causes a waste of resources; if replaced too late, the water quality cannot be guaranteed
