Abstract
A replenishment and recirculation system for photographic processing fluids includes a number of tanks of which at least one is divided into first and second sections by a wall having a top edge which is submerged below the surface of the fluid. Processing fluid is pumped out of the first section of the tank, filtered, and then pumped back into the second section of the tank in a manner to cause the fluid to circulate inside the second section between the bottom of the tank and the top surface of the fluid. The top portion of the circulating fluid flows across the top of the submerged wall and into the first section of the tank to be pumped back into the second container section. Fresh processing fluid is added into the first section of the tank where it mixes with the fluid present therein, before being withdrawn and pumped into the second section of the tank which contains the photographic paper.
