Water Solutions
for the Metal Industry
Metals and critical minerals are essential to energy transition and economic growth worldwide. However, producing them from increasingly complex ores and achieving high purity targets require innovative water and process solutions.
Challenges in the Metal Industry
Metal processing generates highly contaminated wastewater containing:
Heavy metals such as zinc, nickel, copper, lead, and chromium
Oil and grease residues
Cyanides, fluorides, and suspended solids
Variable pH and high chemical oxygen demand (COD)
These contaminants require specialized treatment processes to meet discharge or reuse standards. Uncontrolled discharge can lead to serious environmental and regulatory penalties.
Our Solutions
RoperBerk delivers complete water management systems for both upstream and downstream metal operations:
1- Process Water Treatment
• Filtration, softening, and reverse osmosis (RO) systems for reliable process water quality
• Deionization and ultrafiltration (UF) for high-purity water in plating and coating lines
• Closed-loop systems to minimize freshwater intake
2- Wastewater Treatment
• Heavy metal precipitation and sludge dewatering systems
• Advanced oxidation and chemical dosing units for COD and cyanide removal
• Membrane bioreactors (MBR) and zero-liquid discharge (ZLD) options for sustainable reuse
3- Cooling & Rinse Water Recycling
• Side-stream filtration and chemical treatment for cooling tower efficiency
• Rinse water recovery systems for electroplating and galvanizing lines
• Reuse integration for reduced operating costs and resource conservation
