System and method to sustainable integrated wastewater treatment and air-cooling in a steelmaking plant

A system comprising:

• a wastewater treatment system configured to process wastewater released by one or more furnaces at a steelmaking plant, and generate reused wastewater;
• a heat recovery apparatus coupled to the wastewater treatment system and a freshwater tank through at least one valve to receive a mixture of reused wastewater and fresh water, wherein the heat recovery apparatus is configured to heat the mixture of reused wastewater and fresh water, using exhaust gas from the one or more furnaces at the steelmaking plant, above a threshold temperature;
• and
• a generator coupled to the heat recovery apparatus and configured to receive, through a water inlet of the generator, the mixture of reused wastewater and fresh water heated above the threshold temperature;
• and
• an absorption system in circulation with the generator, wherein the mixture of reused wastewater and fresh water is supplied above a threshold amount such that the generator drives the absorption system and produces cooled air inside the steelmaking plant.
