ABSTRACT:
Apparatus can prewet at least one filter with a supply of liquid and a supply of wetting agent. The apparatus has a container for holding at least the one filter. The apparatus also has a flow arrangement including a circulating subsystem and flushing subsystem. The circulating subsystem is connected to the container and the supply of wetting agent for: (a) circulating the wetting agent through the container during an initial phase, and (b) draining the wetting agent during a subsequent phase back to the supply of liquid. The flushing subsystem is connected to the container and is adapted to be coupled to the supply of liquid for flushing the liquid through the container. After loading a filter into the container, wetting agent is circulated through the container in the initial phase. Then the wetting agent is drained back to the supply of liquid in the subsequent phase. The liquid is flushed through the container without reopening the container, before removing the filter from the container.
