Abstract

The present invention relates to a steel making plant (1) comprising:- at least one apparatus (10) provided with a direct water cooling system (11) which generates a cooling water flow (CW) containing dissolved solids; - a cooling water treatment circuit (100) which is fluidically connected to said direct water cooling system (11) and is suitable to treat said cooling water flow (CW) so as to recirculate to said direct cooling system (11) a recirculating water flow (RW) having a concentration of said dissolved solids below a predefined limit. Said circuit (100) in turn comprises at least one mechanical separation unit (110, 130, 1100) suitable to separate the solids contained in the cooling water flow (CW), generating a sludge flow (S);- a cooling unit (120) which is fluidically connected to said direct water cooling system (11) by means of a return conduit (101b) which closes the circuit as a loop.- The cooling water treatment circuit (100) further comprises at least one electrocoagulation system (1000) which is suitable to treat at least a part of said cooling water flow (CW) so as to facilitate the separation of said dissolved solids from the water in the form of flocs and/or clots separable by said at least one mechanical separation unit (110, 130, 1100), thereby lowering the concentration of dissolved solids in the cooling water flow (CW).
