Automatic Dual-Tank Ion Exchange Resin Water Softener
How does a Water Softener work?
Softeners have been used since the early 1900's to prevent scale in boilers, so the technology is well understood and their performance is predictable and reliable.
They involve a process called ion exchange which uses an ion exchange resin. The resin comprises 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).
A standard wholehouse water softener works on the principle of ion exchange, called "cation exchange." It conditions, or "softens," hard water by substituting sodium chloride (salt) for hard minerals such as calcium, magnesium, and iron.
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After the water treated by sodium ion exchanger, the Ca+ and Mg+ were superseded by Na +.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.
Ion-exchange water softener remove hardness
Hard water is simply water that is rich in minerals such as calcium, magnesium carbonate, and manganese. If you find that soap and shampoo don't lather well, dishes are spotted, the bathtub has a ring, laundry is dingy, and the coffee maker has scale deposits, your home probably has a hard water problem.
Types of Water Softeners
By far the most popular and commonly used type of whole-house water softener is an ion-exchange or "cation exchange" unit, but a couple of other technologies are also available. It's important to understand the differences.
Application
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.
Solving Hard Water Problems
Hard water comes from aquifers and other underground sources that collect dissolved minerals from rockparticularly calcium, magnesium carbonate, and manganese. These minerals give water undesirable characteristics that collectively are dubbed "hardness." The severity of hardness is measured by grains (of mineral) per gallon (GPG) or, in some cases, by parts per million of mineral (PPM). One GPG equals 17.1 PPM.
Technically, any water that contains more than 1 GPG of dissolved hardness minerals is considered hard, but, realistically, water with up to 3.5 GPG is relatively soft. Water with more than 10.5 GPG is very hard. Between these extremes is typical, moderately hard water. You can buy a water test kit online.
