3.2 Backwash

This is the first step of the regeneration process, in which water flows upwards 

through the resin bed to release any accumulation of dirt within the resin bed 
and to fluff the bed, allowing more efficient contact between brine and resin 
during the brine draw stage.

Water enters the resin tank from the bottom and comes out at the top out to 

the drain. 

3.3 Brine Draw

This is the second step of the regeneration process where the control valve 
draws a concentrated brine solution from the brine tank. 

The brine flows through the resin bed in a downward direction, replacing the 
hardness  minerals  captured  during  the  service  stage  thus  restoring  its 
capacity. 

3.4 Slow Rinse

At the end of the brine draw, water is passed through the resin to replace the 

brine and rinse it out into the drain.

3.5 Rapid Rinse

The rinsing flow rate is increased to eliminate any lingering brine pockets 
within the resin. This ensures that the resin is free from any salt prior to the 
return to service.

3.6 Brine tank Refill

Water is refilled into the brine tank.

For total hardness of 300ppm, the service flow for this softener has been set 

to 20 hours before regeneration at a flow rate of equipment specification 
table  

WARNING

3

Any continuous operation above 22m /hr may result in 
channeling, bed compaction, and hardness leakage. 

WARNING

The brine and salt levels in the brine tank should always 
be  checked  to  ensure  there  is  enough  brine  for 
regeneration. 

WARNING

Drain water should not be directed to a garden as the 
high salt content (sodium) affects plant growth.
