Resin Softeners, Water Softening
The problem of many industrial processes is the high presence of limestone that can precipitate or fix itself, so it is important to remove calcium and magnesium ions from water with industrial water softening systems.
A water softening system is made with the use of resins that through an exchange between sodium ions, replaces Ca2+ and Mg2+ ions with Na+ ions, the resin used to soften the water is a strong cationic with sodium cycle.
Specifically, the water softener uses gelular cationic polymeric resins with sodium cycle, the chemical cycle of water softening is as follows:
Ca(HCO3)2 + Na2R g CaR + 2 NaHCO3 : Mg(HCO3)2 + Na2R g MgR + 2 NaHCO3
The softening of primary water is not a purification of water, but an exchange of substances, the water passing through the resin is deprived of calcium and magnesium and replaces it with sodium, the conductivity of the softened water is higher than the same water not softened because of the added sodium.
The complete removal of calcium and magnesium from the water by a softener is suitable for industrial use, because the absence of calcium is equivalent to the absence of calcium carbonate precipitate.
The softening plant consists of one or more columns, more filters guarantee the supply of softened water in a continuous way, there are versions equipped with PLC that manage the use of one or more columns based on the company’s water requirements and the industrial production process.
At the end of the cycle when the saturation of the softener resins takes place, the resins of the softening plants are automatically regenerated with the special reagent obtained from the saturation of sodium chloride in the water (brine), these softening plants do not require the presence of personnel.
Our softeners and their water softening system are built to be completely automatic, the type of softening plant is also designed to measure and is specific to the needs of the company, we can provide the softener or the softening system with several filter columns and with different flow rates.
