Stages of Regeneration….
In normal service the water passes through the inlet, down
through the resin, up the riser tube to the outlet
The first stage of regeneration is the backwash. The valve
reverses the flow of water so that water now travels
down the riser and up through the resin which lifts the
bed and loosens any debris that may be trapped in the
resin. The water then goes to waste.
During this stage water is sucked from the brine
tank. The concentrated brine is mixed with water
from the inlet to reduce the concentration to the
correct level. It travels down the riser and up
through the resin, when the correct amount of
brine has been drawn water from the inlet
continues to be drawn up through the resin to
push the remaining brine through the resin. This
process exchanges the organic molecules attached to the resin for sodium
ions in the brine thus refreshing the resin and making it ready to attract
organics again. During commissioning it is important to observe that water is
being sucked from the brine tank and going to drain
During Rapid rinse water is passed down through the
resin and up the riser (same as in service) then to drain.
This stage flushes out any residual salt and organics that
might be present and re‐beds the resin ready for use.
