Injector & Flow Control Selection
Injector
The injector determines the brine concentration (ratio between brine suction and rinse water) and the brine flow
through the resin bed, thus the contact time between brine and resin. Injector performances vary significantly with
inlet pressure.

Backwash flow control
The backwash flow control determines the resin bed expansion during backwash, independent of the inlet pressure.
The optimal bed expansion is generally obtained at a backwash flow of 1,8 L/min per dm
2
of resin bed surface.
