Resin: used for water softening (removal of calcium and magnesium ions), water desalination, desalination and so on. Ions: What is meant by ion? The softening, desalination, demineralization of the resin is the use of the ions and ion-exchanged water works. Activated carbon: Activated carbon with a pore structure, a large specific surface area of ??the impurities in the water has a strong adsorption effect, can effectively remove organic matter in water to remove water odor, color and so on. Quartz sand: the water filtration treatment, to further reduce the turbidity of the water, but also to further remove pathogenic microorganisms in the water. Quartz sand filter is also sometimes used to remove the water manganese and iron. Generally, boiler water treatment softening resin used in the life of one to three years (based on usage, water quality; resin regeneration maintaining quality, and the situation varies), when the resin is produced when water hardness greater than 5PPM recommended reproduction with brine, salt dosage according to the amount of the resin, are generally required per liter of resin regeneration salt 0.1KG, and look into the resin tank is used for regeneration of the pump or suction device, if it is the former of the salt solution with 10% , which is 20% recycled backwash thoroughly after soaking, produced water hardness is recommended if it can not reduce Again, if regeneration whether or not the review, there is no description of the problem resin failure, do solid waste disposal, the need to re- replacement. doing any form of cleaning are useless. boiler water treatment industrial salt used what damage the resin should be no problem. If you take the water softening system, you need to use industrial salt for regeneration. If you are using a new resin before use you have to use a certain concentration of industrial salt water immersion, so the new resin fully inflated. Of course, if you're using industrial salt which contains a lot of impurities, such as oxidants, iron and the like may cause resin deterioration or contamination. So the best selection of good quality industrial salt. Now a lot of boiler water treatment basically a sun bed - anion bed chemical desalination, industrial salt used therefore relatively less.
