The process involves the chemical precipitation of wastewater. Manufacturing of high carbon steel wire requires the use of large quantities of rinse water, which becomes contaminated with high concentrations of iron, lead, and zinc. A comprehensive wastewater treatment system was designed for a plant which provides a high degree of treatment and produces finished water suitable for recycle and reuse in the manufacturing process. The wastewater is treated by chemical precipitation.
Careful attention is paid to caustic cleaners which upset the system.
These wastestreams are diverted from the system. The facility has realized significant benefits from treated water recycle and reuse. The wastewater treatment and recycle procedure limits waste and reduces water and sewer rates.
