Abstract

Liquid to be treated goes to a chamber below the tank, with an auxiliary discharge provided by a central tube which opens into a safety chamber. Pref. excess liquid is either provisionally stored in the safety chamber or tipped out by overflow to the normal drain or another recovery tank in series. The central tube and upper and lower plates can be used to remove, in one block, the metal wool and the argentiferous sludge.
