What is water softening?

When water contains a significant amount of calcium and magnesium, it is called hard water. Hard water is known to clog pipes and to complicate soap and detergent dissolving in water.
Water softening is a technique that serves the removal of the ions that cause the water to be hard, in most cases calcium and magnesium ions. Iron ions may also be removed during softening.
The best way to soften water is to use a water softener unit and connect it directly to the water supply.



Working principle
Water softeners are specific ion exchangers that are designed to remove ions, which are positively charged.
Softeners mainly remove calcium (Ca2+) and magnesium (Mg2+) ions. Calcium and magnesium are often referred to as 'hardness minerals'.
Softeners are sometimes even applied to remove iron. The softening devices are able to remove up to five milligrams per litre (5 mg/L) of dissolved iron.
Softeners can operate automatic, semi-automatic, or manual. Each type is rated on the amount of hardness it can remove before regeneration is necessary.

A water softener collects hardness minerals within its conditioning tank and from time to time flushes them away to drain.
Ion exchangers are often used for water softening. When an ion exchanger is applied for water softening, it will replace the calcium and magnesium ions in the water with other ions, for instance sodium or potassium. The exchanger ions are added to the ion exchanger reservoir as sodium and potassium salts (NaCl and KCl).

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.
