Effectively treating wastewater produced by the metal plating, electroplating and finishing industry can be difficult depending upon the composition of the wastewater. Pretreatment is necessary to remove oils, heavy metals and solids and must comply with Publicly Owned Treatment Works (POTWs) strict permit requirements.

Treating metals found in the waste stream and sludge is a necessity for both small and large facilities. From bath dips and rinses to washers and anodizing Operators Unlimited assists our metals finishing customers through a variety of treatment services. From chemical supply and optimization to system design and operations our experienced team has decades of experience to accurately assess your current process and make recommendations for system enhancements to remain fully compliant.

One of the biggest challenges faced by our customers is getting metals concentrations down to appropriate permit levels and the overall disposal costs of hazardous liquids and solids. OU’s services aid plant managers in managing these overall costs associated with the wastewater treatment process and the ongoing capital and maintenance costs of equipment.

Sludge dewatering is an integral part of the metals finishing wastewater treatment process. Dewatering is the process of removing liquids from the sludge slurry for reuse or disposal. Operators Unlimited has successfully implemented and enhanced the efficiency of current dewatering systems, using techniques and technologies and based on customer budget, footprint and overall system process.
