What is the reason for the deterioration of water quality in the long-term use of small-scale industrial softened water treatment equipment? Author: Water softening bring many benefits to both our daily lives and industrial production will, in particular, the northern region of high water hardness, in order to improve water quality, water softening equipment but a small number of SMEs are often used in long-term use The water quality of industrial softening water treatment equipment is softened. Therefore, water softening equipment has gradually been recognized and used by the majority of users. Some users find that the effluent quality has deteriorated after using the small industrial softened water treatment equipment for a period of time. Why? Let us find out the reasons for the deterioration of the effluent quality of the water softened equipment. 1. The ratio of the water supply TDS value to the height of the resin layer or the resin exchange capacity is too large. Compared with the initial test of the new resin, the water softening equipment has stricter requirements on the TDS value of the water supply. When the height of the resin layer is 1.5 meters, the total hardness is 13mmol/L, and the TDS value of the water supply is greater than or equal to 900mg/L, ensure that the hardness of the soft water is ≤0.03 mmol/L will be more difficult. 2. Check whether the resin is poisoned. Sometimes the resin exchange capacity decreases due to long-term use and aging. Excessive hardness of the soft water caused by this reason is a gradual process, not a sudden and obvious excess. Factors such as high heavy metal content in the water cause resin poisoning. Slight poisoning can be resuscitated with hydrochloric acid, and severe poisoning is generally not treated and basically discarded. 3. The amount of salt in the salt tank is too small. When the amount of water in the salt tank is normal and the height of the salt is less than 1/3 of the height of the water, the salt water sucked in the middle and late stages of the salt absorption step is likely to be unsaturated, causing the salt water concentration diluted by the jet to be lower than the regeneration requirement , Affect the regeneration effect. 4. The total amount of water in the salt tank is too small. Our experience is that for every 100L of resin in the resin tank, the required amount of water in the salt tank is about 35-40L. Too much water below this standard will cause insufficient regeneration. 5. Suction of salt water is too slow. In normal time, it is impossible to inhale enough salt water. The reasons are as follows: the feed water pressure is too low, the mud and sand and other debris in the upper and lower water are blocked seriously, and the waste water hose is deformed and bent. The waste water is not smooth, there are too many impurities in the resin layer, and there are leaks on the salt suction pipeline, so that air is sucked in, there are foreign objects in the jet, the air check valve fails, it is closed or blocked in advance, and the jet selection is too small. 6. The jet is blocked, the water inlet filter of the equipment is blocked, or the water distributor is blocked. 7. The purity of sodium chloride is not enough. This phenomenon is true, which means that the salt you use is fake, and it can be proved by comparing it with the instructions. 8. The inlet water pressure is too low. 9. The internal control valve of the small industrial softened water treatment equipment is leaking. 10. The salt valve is leaking or the blockage is blocking the pipeline, and the blockage is not cleared for the equipment in time. Here is a brief introduction to the reasons for the unqualified water production of several small industrial softened water treatment equipment. Users can check the small industrial softened water treatment equipment according to the above content and solve the problems in time.
