Many users may not have paid close attention to this issue. The interval between tests for the water output from such equipment depends mainly on the quality requirements set by the organizations that use this water. Below, the editor will provide some information on this topic. Different industries have varying requirements for the quality of the produced water. In industries where the requirements for water quality are not very high, the conductivity of the water produced by chemical ultra-pure water treatment equipment is higher than that of ordinary water, which means that frequent testing is not necessary; usually, testing once a month is sufficient. For industries with high requirements regarding water quality, such as the electronics industry and those that use precision materials, water quality must be tested on a daily basis. Poor water quality can directly lead to a decline in product quality, thereby increasing production costs. Measuring conductivity is relatively simple and takes little time – only a few minutes. Even if the conductivity of the EDI equipment is checked daily, it won’t take up too much time. Furthermore, users with very strict requirements regarding water quality use real-time monitoring to identify water quality issues by testing conductivity. This helps to reduce troubleshooting time when the system fails.
