Abstract
A process for the treatment of cooling waters, particularly in thermal power stations, without or--optionally--with partial acid decarbonization of the make up water, the improvement wherein the make up water is mechanically coarse-clarified and the hardness is then stabilized with scale inhibitors. The scale inhibitors are then removed from the blow down and are optionally recovered.
