The factors affecting water softener exchange capacity

Water softener is implemented by exchanging the calcium and magnesium ions in the water softening of water, then influence the water softener exchange capacity what? We have summed up the following aspects:

1, the design flow rate, usually the work layer, the greater the needed velocity, the greater the ion exchange resin and the effective utilization rate will drop, water softener water production capacity will increase, but the small flow rate will cause the raw water with ion exchange resin surface only, water will not enter inside resin, but the surface only provides 20% of the capacity of the resin, the resin to provide 80% of flux, so the exchange capacity and velocity has a lot to do, we filter the source water treatment equipment company in several years' practice prove that water velocity in 18 ~ 30 m/h, the velocity is the most reasonable.

2, water and contact time of the resin, the longer the contact time, water and resin exchange more fully, but water rate is falling, we recommend in 8 ~ 4 bv/h.

3, the resin layer height, the lower the resin layer, because of the greater is the impact on the velocity of the exchange capacity, when the resin layer of 750 mm, then the velocity influence on the exchange capacity can be reduced to a lower range, we suggest that the resin layer is more than 750 mm.

4, feed water salinity, water salinity level directly affect the quality of the water, and the potassium ion and sodium ion content in the feed water salinity effect on effluent water quality is very great.

5, temperature, temperature increase can increase the exchange capacity, the increase in appropriate temperature is good for water softener.

6, quality of regenerative agent and regeneration of liquid flow rate and concentration of renewable liquid, the higher purity of regenerative agent, resin regeneration effect is good, resin exchange capacity restore good, renewable liquid concentration general at around 10% for the best.
