Water Softener

Water softener, equipment used to reduce the hardness of water , in addition to remove calcium and magnesium ions in the softened water softening equipment in the process, does not reduce the total salt content of the water

As water hardness mainly calcium and magnesium to form and that it is commonly used cation exchange resin ( water softener ) , the water of Ca2 +, Mg2 + ( the formation of scale main ingredients ) displace , with resin Ca2 +, Mg2 + increases, resin to remove Ca2 +, Mg2 + decreased performance .
When the resin to absorb a certain amount of calcium and magnesium ions, it must be carried out , and the regeneration process is the salt in the salt water rinse resin layer , the hardness of the resin ion exchange out with recycled waste water discharge tank , the resin soften and restore the switching function .
As water hardness mainly calcium and magnesium to form and that of the water hardness mainly calcium and magnesium to form and that sodium ion exchange softening the principle of raw water through the sodium cation exchange resin , so that the water hardness components Ca2 +, Mg2 + and resin in Na + -phase switching, thereby adsorption of Ca2 +, Mg2 +, the water is softened . As representatives of the RNa sodium resin , the exchange process is as follows:

2RNa + Ca2 + = R2Ca + 2Na +
2RNa + Mg2 + = R2Mg + 2Na +

The water through the sodium ion exchanger , the water, Ca +, Mg + is replaced by Na +.
General control valve operation process is: run , backwash , brine , slow wash , salt water tank , flushing .

1 ) equipment Workflow
Work ( sometimes called a water , the same below ) , backwash , brine ( regeneration ) , slow rinse ( replacement ) , quick rinse five processes . Different softening equipment, all the processes are very close , but different , or the actual process control needs , there may be some additional processes. Any sodium ion exchange water softening equipment based on these five processes are developed on the basis come ( which will increase the automatic water softening equipment brine re-injection process ) .

Backwash: After working device , the upper block in the resin to bring a lot of raw water dirt, removal of these contaminants , the ion exchange resin to be fully exposed out of the effect of regeneration can be guaranteed. Backwash process is the wash water from the bottom of the resin into , out from the top , so you can put the top block down the dirt away. This process usually takes about 5-15 minutes .

Absorption of salt ( regeneration ) : Coming into the resin tank brine process is the use of traditional equipment salt brine pump , automatic equipment is built by private jet to saline inhalation ( as long as there is a certain pressure to the water ) . In the actual work process, brine flowing at a slower rate than the simple effect of resin regeneration brine resin effect, so use saline water softening devices are slow flow through the resin regeneration, this process usually takes 30 minutes of actual time enough salt .

Slow wash ( displacement ) : After the salt water through the resin , with the raw water at the same flow rate of the resin in the salt slowly rinse all the washing process is called slow , as this washing process there are a large number of functional groups on the calcium and magnesium ions are sodium ion exchange , based on actual experience , this process is the main process of regeneration , so many people will this process is called substitution . This process is generally the same time with the absorption of salt , that is about 30 minutes.
Fast Flush : In order to thoroughly rinse the salt residue , to be used close to the actual work flow, with the raw water to wash the resin , the process of the final effluent standard soft water . Generally , the fast rinse process is 5-15 minutes.

water softener Application

Widely apply to industry and civil softened equipment, like boiler water supply, heat supply, air conditioner system water supply and high quality domestic water, etc.
