A Primer on Industrial Wastewater Treatment for Metalworking Manufacturers
Industrial wastewater treatment and wastewater management are critical concerns for metalworking industries, encompassing metalworking engineers, maintenance staff, plant managers, production managers, and mechanical engineers. Effective treatment systems ensure environmental compliance, enhance operational efficiency, reduce costs, and promote sustainability. PRAB, Inc. offers comprehensive solutions tailored to these needs, setting a benchmark in the industry.
Understanding Industrial Wastewater in Metalworking
In metalworking, machining, stamping, and surface finishing generate wastewater laden with contaminants like oils, greases, heavy metals, and suspended solids. Proper treatment is essential to prevent environmental pollution, meet regulatory standards, and optimize water reuse within operations.
PRAB’s Comprehensive Wastewater Treatment Solutions
PRAB provides a suite of industrial wastewater treatment systems designed to address the unique challenges of metalworking industries:

- Ultrafiltration Systems: Utilizing crossflow filtration, these systems effectively remove emulsified oils and suspended solids from soluble oils and alkaline wash waters. The process involves fluid flowing parallel to a semi-permeable membrane, retaining contaminants while letting water and dissolved solids pass through. This method produces consistent effluent quality suitable for discharge or reuse, leading to significant cost savings and compliance with environmental regulations.
- Vacuum Evaporation and Distillation: PRAB’s EVALED® Vacuum Evaporators concentrate wastewater by evaporating the water content, leaving behind concentrated waste. This energy-efficient technology can handle various wastewater types, including those with high contaminant loads, reducing disposal volumes and costs.
- Automated pH Adjustment Systems: optimal pH levels are crucial for effective wastewater treatment. PRAB’s automated systems monitor and adjust pH levels in real-time, ensuring compliance with discharge regulations and enhancing the efficiency of water treatment processes.
- Oil/Water Separators: Designed to remove free-floating and mechanically dispersed oils from industrial wastewater, these separators improve water quality and reduce the burden on downstream treatment processes.
Case Study: Enhancing Wastewater Management Efficiency
A notable example of PRAB’s impact is when a metal finishing company faced challenges with rinse water containing heavy metals and other contaminants. By implementing PRAB’s ultrafiltration system, the company significantly reduced wastewater volume and contaminant levels, lowering disposal costs and improving compliance with environmental regulations.
