ABSTRACT:
A sidestream of injection liquid taken downstream of a filter is passed through a monitoring filter of appropriate pore size. Pressure drop over the monitoring filter is determined and a regeneration cycle for the main filter is triggered in response to differential pressure (.DELTA.P) over a preset value, which corresponds to deterioration in filtrate quality.
