Disclosed is a simple, economical ion exchange system for cleaning water, particularly rinse water from plating operations. Two or more identical cannisters with clear plastic sidewalls are connected in series and each contains resin in a central zone for removing anions or cations from water pumped from a reservoir through the cannisters. The resin material is held between permeable separator plates which also define inlet and outlet plenums accessible through openings in the sidewall near opposite ends of each cannister. The identical cannisters are stackable in one or more vertical arrays containing any suitable number of cannisters. Standard screw-type pipe fittings connect the inlet and outlet of successive cannisters to facilitate rapid disassembly of a multi-cannister ion exchange system and removal/replacement of cannisters whose resin requires regeneration.
