<p>It is known to separate photographic effluent into solid and liquid phases for disposal. Described herein is an apparatus (10) and method for treating photographic effluent which utilises a sedimentation tank (14). The sedimentation tank (14) allows the solid phase to settle out of the effluent to produce a boundary between the settling solid and generally liquid material, the liquid phase being removed from the tank (14) through outlet means (42, 54). As the boundary approaches the upper part of the tank (14), the contents thereof are pumped through filter means (22, 26) to separate the solid from the liquid. <IMAGE></p> |
