Method and device for detecting whether weakly acidic resin is in failure or not

Abstract

The invention provides a method and a device for detecting whether weakly acidic resin is in failure or not. The method comprises the following steps of (1) detecting the TDS (Total Dissolved Solids) value of a water sample, thus obtaining the first TDS value; (2) filtering the water sample by utilizing the weakly acidic resin, thus obtaining a filtered water sample; (3) detecting the TDS value of the filtered water sample, thus obtaining the second TDS value; (4) determining whether the weakly acidic resin is in failure or not based on the first TDS value and the second TDS value. According to the method for detecting whether the weakly acidic resin is in failure or not, provided by the invention, whether the weakly acidic resin is in failure or not can be determined by detecting the TDS values before and after filtering the water sample, the cost is lower, the technology maturity is high, and the reliability is good.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a method and equipment for detecting whether a filter element fails. Background technique [0002] Weakly acidic resin can remove the alkalinity and part of the hardness in water, and can produce weakly acidic softened water. This kind of water can protect the weakly acidic protective film of human skin and care for skin health. Usually, weakly acidic resin will pre-purify the filter element, and the purification filter element can Removing residual chlorine, impurities and some harmful organic substances in the water, the purified water can better protect the skin, and at the same time, the purified water passes through the weak acid resin, which can effectively protect the resin and prolong the service life of the resin. [0003] The service life of weakly acidic resin can be directly reflected by the removal of alkalinity, hardness test or pH value test. Since the effl...

AI Technical Summary

Problems solved by technology

The hardness test is more complicated, and it cannot fully reflect the functional characteristics of the water effluent of the weak acid resin

In addition, due to the large differences in the alkalinity and hardness of tap water in various places, it is not accurate enough to calculate the service life by using simple usage time

[0005] Therefore, the current detection technology for the use status of weak acid resin or weak acid softening filter element still needs to be improved.
