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.

Abstract: Systems for continuous granulated metallic unit (GMU) production, and associated devices and methods are disclosed herein. In some embodiments, a continuous GMU production system includes a furnace unit, a desulfurization unit, a plurality of granulator units, and a cooling system. The furnace unit can receive input materials such as iron ore and output molten metal. The desulfurization unit can reduce a sulfur content of the molten metallics received from the furnace unit. Each of the plurality of granulator units can include a tundish that can control the flow of molten metallics and a reactor that can granulate the molten metallics to form GMUs. The cooling system can provide cooled water to the reactor. Continuous GMU production systems configured in accordance with embodiments of the present technology can produce GMUs under continuous operations cycles for, e.g., at least 6 hours.

Abstract: Reduced-waste systems and methods for granulated metallic units (GMUs) production are disclosed herein. A representative method can include receiving a first supply of molten iron and producing GMUs by granulating the molten iron poured onto a target material of a reactor. The method can include removing residual fines of the GMUs via a classifier based on a threshold particle size and mixing the residual fines with a second supply of molten iron to produce additional GMUs.
