摘要：Apparatus for removing suspended solids from electroplating solutions and the like includes a housed cluster of slotted plastic tubes about which are fitted fabric filter sleeves and through which the solution is normally forced into the tubes continuously in the course of filtering. The process is interrupted relatively briefly when likely to be impaired by solids build-up, and flushing with water at a common utility-source pressure is then uniquely valved to take place in the reversed direction sequentially through the several sleeves by way of relatively slender sparger pipes each mated within a companion one of the slotted tubes and proportioned to spray a multiplicity of fine high-velocity streams through the slots and forcefully directly against the surrounding filter sleeving, to dislodge particulate material for drainage.
