The reason for the large change in the hardness of the effluent water quality of the medium and small industrial boiler softening water equipment? Author: We have a certain understanding of the scale, the scale affects our life and good health to a large extent, this time the importance of small and medium sized industrial boiler water softening equipment is manifested. Some users have found that the effluent quality of small and medium-sized industrial boiler softening equipment is unstable, and sometimes there is a phenomenon that the hardness exceeds the standard. What is going on? Let us understand the reason for the large change in the hardness of the effluent water quality of the small and medium-sized industrial boiler softening equipment . 1. The hardness of the tap water increases suddenly. The reason for the increase may be that the groundwater changes due to seasonal factors, or it may be that the chemicals added in the water plant have not been cleaned, etc., check it for verification. 2. Sometimes the resin is poisoned due to long-term use and high heavy metal content in the water. Slight poisoning can be resuscitated with hydrochloric acid, and severe poisoning is generally not treated and basically discarded. 3. The purity of sodium chloride is not enough, which means that the table salt you use is fake, which can be proved by comparing it according to the instructions. 4. The resin is invalid and the exchange capacity is not enough, just replace the resin. In fact, resin failure is not necessarily gradual, and some factors may accelerate resin failure. You can put the resin into a burette, use a washing ball to slowly add water from the top, and use two barrels below to sample. Do this experiment to prove whether the resin has failed. 5. The anti-corrosion layer of the metal resin tank is peeled off, and the tap water has been in the pipeline for too long, which makes the iron ions in the water too high, causing resin poisoning.
