Water Treatment for Metal Fabrication and Finishing
In metal fabrication and finishing, water is essential to key processes like rinsing, plating, surface preparation, and wastewater treatment. Effective water treatment supports product quality, helps protect equipment, and reduces operational costs and environmental impact. At Culligan Texas, we offer tailored water treatment solutions built to support the specific demands of metalworking facilities.
Whether you’re looking for high-purity water for finishing operations, strategies to minimize wastewater discharge, or systems for water reuse and sustainability, our technologies are designed to meet your facility’s exact needs.
For over 74 years, we’ve delivered high-performance water treatment solutions tailored to the complex demands of metal fabrication and finishing operations, such as:
- Plating Bath Water Conditioning – Maintain the correct chemical balance and purity to improve coating adhesion and finish consistency.
- Rinse Water Quality Control – Reduce spotting, staining, and rework by ensuring high-purity rinse water in multi-stage wash and plating lines.
- Closed-Loop Rinse Systems – Capture, filter, and recirculate rinse water to reduce water usage and minimize chemical discharge.
- pH Neutralization & Heavy Metal Removal – Treat wastewater to safely remove contaminants like chromium, nickel, and zinc before discharge.
- Cooling System Water Treatment – Prevent scale and corrosion in cooling towers and closed-loop systems used in metal cutting or welding operations.

Water Quality Targets & Treatment Insights for Metal Finishing
- Typical rinse water contains oils, chromium, and nickel—RO systems remove 95–98% of these contaminants and support water recycling, thereby reducing discharge costs.
- Conductivity-controlled rinse tanks can reduce water usage by up to 43% by adding fresh water only when needed.
- pH adjustment precipitates heavy metals, such as zinc and nickel, reducing their concentrations to below discharge limits.
- Hexavalent chromium is reduced to the trivalent form at low pH, then removed as chromium hydroxide.
