Two-stage water softening equipment

WR Series Automatic sodium ion exchange is a centralized process controller with integral control valve automatic water softening systems. Program controller issued under preset control program (control mode is time controlled or flow control) to the centralized control valve command, control valve automatically complete valve opening and closing different channels, thereby achieve autonomous operation (softened), backwash, regeneration such as recycling step process. Meanwhile Automatic sodium ion exchange venturi principle of absorption of salt spray, self-injection of salt, the concentration ratio, without salt pump, dissolved salt and other ancillary equipment. And because the automatic operation can achieve continuous water supply. The product has been widely used in construction, chemical industry, metallurgy, rubber, textile, coal, food, refrigeration and other industries cooling, air-conditioning water system, boiler hot water circulation system, ground water circulation system. 2, the working principle of the water hardness which is mainly composed of calcium (Ca2 +), magnesium (Mg2 +) ions formed, automatic sodium ion exchange ion exchange principle, the removal of calcium and magnesium ions scaling. As with the hardness ions in raw water through the inner exchanger resin layer, water calcium and magnesium ions then replaced occurrence and resin adsorption of sodium ions, resin adsorption of calcium and magnesium ions and sodium ions into the water, so that the outflow from the exchanger remove the hardness of the water is softened, with the exchange process, the resin is gradually calcium, magnesium ion saturation exchange capacity of the resin drops, until we lose the ability to soften the exchange, then the resin must be regenerated: recycled agent ( saturated brine NaCl) in amounts of sodium ion resin adsorption of calcium and magnesium ions displace the resin re-absorption of sodium ions, the ability to recover in the softening exchange.
