Softening Water Principle: When the raw water has a high content of calcium and magnesium ions, the ion exchange resin (a polymer with corresponding functional genes, and sodium ion exchange resin contains a large number of sodium ions) can release sodium ions, which bind with the calcium and magnesium ions, thereby reducing the content of these ions in the water, lowering the water hardness, and converting hard water into soft water. The water hardness is mainly composed of cations: calcium (Ca2+) and magnesium (Mg2+) ions. When the hard water passes through the resin layer of the exchange unit, the calcium and magnesium ions in the water are adsorbed by the resin while sodium ions are released. The water flowing out of the exchange unit is then softened, free of hardness ions. Once the resin adsorbs calcium and magnesium ions to a certain saturation point, the hardness of the outflowing water increases. At this point, the water softener will automatically regenerate the exhausted resin according to a predetermined program, using a high-concentration sodium chloride solution (brine) to pass through the resin, restoring the exhausted resin back to sodium-type resin. Equipment Models: 0.5 ton/hour – 1000 ton/hour. Equipment Selection Considerations: Consider the peak production water demand, the hardness of the raw water, and whether the equipment operates for more than 8 hours per day. Equipment Purchase Considerations: Resin brand, exchange capacity, regeneration control method, and whether equipment over 30 tons has the brine immersion function.
