What is hard water?
When water is referred to as 'hard' this simply means, that it contains more minerals than ordinary water. These are especially the minerals calcium and magnesium. The degree of hardness of the water increases, when more calcium and magnesium dissolves.
Magnesium and calcium are positively charged ions. Because of their presence, other positively charged ions will dissolve less easily in hard water than in water that does not contain calcium and magnesium.
This is the cause of the fact that soap doesn't really dissolve in hard water.
Which industries attach value to hardness of water?
In many industrial applications, such as the drinking water preparation, in breweries and in sodas, but also for cooling- and boiler feed water the hardness of the water is very important.
Automatic Water Softener
in brief, water softeners are designed to remove calcium and magnesium (the cause of scale and scum) from hard water. They are intended to treat the whole house, so are installed where the water supply enters the premises.
Ion Exchange
Water softening happens through a process called ion exchange, which uses an ion exchange resin. The resin comprises of tiny polymeric beads which are specially formulated so that they can be charged with certain ions. Calcium and magnesium, the causes of scale and scum from hard water, are referred to as ions, and as water passes through the resin, the calcium and magnesium ions swap places with the sodium ions on the resin. Sodium salts, unlike calcium and magnesium, are highly soluble so sodium does not cause scale or scum. When all the sodium ions have been exchanged for calcium or magnesium, the resin must be regenerated by recharging it with sodium ions. This is done by flushing the resin with salt solution (brine).
Working principle
01. By means of Absorbing the calcium and magnesium ions in water with resin, since the hardness of water is mainly composed of calcium and magnesium, in general, we adopt cation exchange resin (softener), replace Ca2+, Mg2+ (main ingredients for scale) in water, as the increase of Ca2+ and Mg2+ in resin, removing performance on Ca2+, Mg2+ of resin will gradually reduce.
02. When the resin has absorbed a certain amount of calcium and magnesium ions, it must be regenerated, the regeneration process is that flush resin layer with the salt water in salt box, replace hardness ion out of the resin again, and discharged from the tank with waste liquid of regeneration, then resin resumed the function of softening and exchanging.
03. The principle of sodium ion exchange and softening treatment is to exchange cation in the raw water with resin, hardness constituents Ca2+and Mg2+ in water exchange Na+ in resin, thus absorb the Ca2+and Mg2+ to make the water to be softened.
2RNa + Ca2+ = R2Ca + 2Na+
2RNa + Mg2+ = R2Mg + 2Na+
After the water treated by sodium ion exchanger, the Ca+ and Mg+ were superseded by Na +.

Application scope of softener
Mainly used in industry and civil water softening preparation, such as Boiler feed water make-up water, air conditioning system make up water, heat exchanger, power plant, chemical, textile, printing and dyeing, bio-pharmaceutical, Electronic system and water pretreatment.
Control mode of fully automatic water softener
(1) Single tank time type: It adopts microcomputer to control the time, when operation of the equipment reaches setting time, it will automatically enter the regeneration condition, which can be regenerated for once a day or once for some day.
(2) Single tank flow type: It adopts control of turbine flow or electronic flow sensor, when the yield of softener reaches preset flow it will automatically enter the regeneration condition, which can be recycled many times every day.
(3) Double tanks flow type: Which could be divided into one running-one alternating, and simultaneous running and separately regeneration.
(4) One running and the other alternation type: One tank is running while the other is alternating, when water yield of operating tank reaches the preset flow rate, it will enter the regeneration stage, meanwhile, the other tank will enter the working state, these two tanks work and regenerate alternatively to realize continuous water supplying of 24 hours.
(5) Simultaneous running and separately regeneration type: Two cans running simultaneously, when the flow rate reaches the setting rate, one tank (can) will regenerate and the other tank will output water continuously, when the first regeneration tank finish the regeneration it will enter the working stage, the other one will enter regeneration stage, these two cans finish regeneration and enter working state simultaneously.
