The working principle of water softening equipment

The hardness of water mainly depends on the cations in it: calciumCa²⁺MagnesiumMg²⁺Ionic composition. When the raw water with hardness passes through the resin layer of the exchanger, calcium and magnesium ions in the water are adsorbed by the resin, while sodium ions are released. The water flowing out of the exchanger in this way is softened water with hardness ions removed. When the resin that adsorbs calcium and magnesium ions reaches a certain level, the hardness of the effluent increases. At this point, the water softener automatically performs the regeneration of the exhausted resin according to the predetermined program, using a higher concentration of sodium chloride solution to pass through the resin to restore the exhausted resin to the sodium type resin.

The application scope of water softening equipment

Industrial boilers, air conditioners, heat exchangers, hotels and restaurants, chemical industry, laundry and dyeing, hygiene and other industries.

The main features of water softening equipment

1It features a high degree of full automation, stable water supply conditions and a long service life. The entire process operates automatically, requiring only regular manual salt addition.

2High efficiency, low energy consumption, and low operating costs. Due to the reasonable overall design of this water softener, the exchange capacity of the resin is fully exerted. The energy consumption indicators of the equipment itself are significantly lower than those of general water softening equipment. The automatic control equipment does not require full-time operators, which brings many conveniences to users and generates good benefits.

    BSalt consumption: It is approximately required to regenerate one liter of resin160～240The specific salt consumption per gram should be determined based on the water quality indicators of the user's raw water.

    CElectricity consumption:3～40WSince no salt pump is needed and it adopts220VThe power consumption of a common lighting power supply is only that of a common water softener1%.

3The equipment has a compact structure, occupies a small area, and does not require a dedicated equipment foundation. It can be directly placed on a flat cement floor.

4It is easy to use, with simple installation, debugging and operation. The control components are stable in performance, which can relieve users of their worries.

5The control valve body is made of corrosion-resistant, pollution-free and lead-free brass, with an inner liningPEPlastic exchange tankPEThe material of the salt tank is sufficient to ensure the excellent performance of this equipment in terms of corrosion resistance, anti-pollution, odorlessness and harmlessness.

Working procedure of water softening equipment

1Water supply: Untreated water passes through the resin layer and undergoes an exchange reaction to produce soft water.

2Backwashing: Water enters from the bottom of the resin layer, loosening the resin and removing fine debris.

3Salt regeneration: Utilizing brine with a higher concentrationNaClFlowing through the resin, the exhausted resin is restored to the sodium form of usable resin.

4Rinsing: Follow the water supply process to allow water to pass through the resin to wash away the excess brine and the calcium and magnesium ions exchanged during regeneration.

5Water supply: Fill the salt tank with water to dissolve the salt grains for the next regeneration.

Control mode of water softening equipment

1Time control: Suitable for places with relatively stable daily water supply. When the regeneration time set by the user is reached, the regeneration process will be automatically initiated.

2The regeneration time can be set by the user according to their needs during the off-peak water usage period. This control mode features: simple control method, low cost and easy operation. This system is mainly used for systems with relatively low hardness4mmol/L),Stable water usage (the fluctuation in water usage does not exceed.15%In cases where the effluent requirements are not high and the water consumption is relatively small.

3Flow control: The operation of this equipment is calculated by a flowmeter for flow. When the water volume reaches the set value, regeneration will be automatically initiated. The set value of water volume is calculated based on the working exchange equivalent value of the exchanger and the hardness equivalent value of the influent water. This system features high precision, stable and reliable water output, and is equipped with a memory function. There is no need to reset the values after a power outage.
