How Water Softeners Work
The best way to learn about how water softeners work is to book one of our demonstrations, you'll be able to see softened water in action from your own tap.
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).


Type choice:
Softener equipment applies cation resin for softing raw water,its main target is to use cation resin to adsorp (main parts of ),encreasing the hardness of raw water.
1. Users can choose manual operation control system for saving cost.
2. If users using for 24 hours can accord to water using time choosing for rebirth
3. Uses can according to water quality requirement:first grade multi-media filter,which can remove mud,rust,colloid and suspension in water.Second grade activated carbon filter,which can remove color,olfactory,biochemistry organic in water and encrease the left oxygen value and pollution in water.Third grade equiped softener equipment.
4. Effluent water capacity achieves the water supply of national low-pressure bioler.
5. Time control- type;flow control- type.In working ,apply single-tank,double-tank and multi-tank etc. other varied combination method.When choosing,users can choose as their needs.In operation,it has not only automatic function,but also is manual operation.
 
Technical Parameters
Type I : Single-tank and single-valve( flow rate based control)  
Type II.dual-tank and dual-valve, two tanks work simultaneously but regenerate at different time 
Type III.:dual-tank and single valve,one work one standby
