Abstract

Treating cooling water in industrial production facilities and associated systems, devices, and methods are disclosed herein. The system can comprise a cooling tower with a first and second cell, each having a housing to receive return water and a sump below to maintain supply water configured to directly contact molten metal. The system includes an inlet and an inlet line to provide return water to the cooling tower and an outlet and an outlet line to direct supply water back to the industrial production facility. The inlet, outlet, and cooling tower form a closed-loop network. Additionally, a blowdown line is fluidically coupled to the outlet to divert a portion of the supply water away from the closed-loop network.
