In an electro-plating or similar processing installation, where bulk items 3 are processed in a perforate treatment barrel 2, liquid is removed from the barrel 2 and the contained bulk items 3 by placing the barrel 2 in a prismatic chamber 1 the dimensions of which conform closely to the shape of the barrel, the chamber having an air blowing duct 12 and an air suction duct 11 both opening into a lower part of the chamber 1. Air is then circulated through the chamber, by drawing air out of the chamber through the air suction duct 11 and blowing air into the chamber through the air blowing duct 12. The air stream 4 will thus flow through the barrel 2 in the chamber 1 and over the surfaces of items contained in the barrel. Liquid may be recovered at the original concentration from the air stream 4 for re-use in a treatment bath. Rinsing may simultaneously be performed by spraying water into the chamber, or the process may be operated to perform drying of the bulk items. <IMAGE>
