Softening Water Principle: When the raw water has a high concentration of calcium and magnesium ions, the ion exchange resin (which is a polymer with corresponding functional genes; sodium ion exchange resin contains a large amount of sodium ions) can release sodium ions, and the functional genes bind with calcium and magnesium ions. This reduces the concentration of calcium and magnesium ions in the water, lowering its hardness, and turns the hard water into soft water. The water hardness is mainly composed of cations: calcium (Ca2+) and magnesium (Mg2+) ions. As the hard water containing these ions passes through the resin layer of the exchange unit, the calcium and magnesium ions 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 outgoing water hardness increases. At this point, the water softener will automatically regenerate the exhausted resin according to a predetermined program. This is done by passing a concentrated sodium chloride solution (saltwater) through the resin, restoring the exhausted resin to its sodium form. Equipment Model: 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's daily operating time exceeds 8 hours. Equipment Purchase Considerations: Resin brand, exchange capacity, regeneration control method, and whether equipment over 30 tons has the saltwater immersion function.
