Abstract
Disclosed is an arrangement of distribution columns that can be used to discharge the declogging fluid from a filter with automatic declogging or backwashing. A stationary divider is arranged coaxially in a stack of filter elements and has distinct ducts, e.g. embodied by fins, the ducts establishing communication between a rotary distributor and groups of passages in the stack that are in alignment along generator lines of the stack.
