Ion-exchange Water Softener
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).
Our Machines
Our softeners have tanks to hold the resin which the water supply moves through in order to soften it. When required, salt is dissolved for the regenerating brine and one cylinder is regenerated while the other continues to serve softened water. This duplex parallel system is unique to Harvey water softeners. It makes regeneration even more efficient in terms of water usage since softened water is more ideal for the regeneration process (it does not contain calcium and magnesium ions that regeneration removes). There are various ways in which softeners determine when to regenerate - some are fitted with a timer and some regenerate after a pre-set volume of water has been treated.
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.
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.

System automatic water softener widely used in steam bioler,heating bioler,exchanger,air conditioner, and other systems water softener,also used in hotel,restruant,office, and other life water treatment and food,drinking,wine,washing,textile,chemical,medicine and other industrial softener water treatment.
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
Our softeners are effective in:
Preventing scale in the hot water system and around taps
Removing existing scale
Reducing boiler fuel cost and heating system maintenance costs
Preventing soap scum, which is evident around the bath and sink
Improving the texture of laundry by preventing detergent scum deposits within the fibers of clothes, bedding, etc.
Reducing soap and detergent costs.
