Family-founded in the mid-1980s, Mercer International grew out of field engineers’ efforts to correct industrial wastewater systems that failed in actual operation. The company is known for an engineering-first approach to enhanced-gravity oil-water separation, designing equipment around real operating conditions rather than relying on generic sizing or short-life media. Mercer serves operators whose treatment systems must remain serviceable over decades, including industrial facilities and critical infrastructure.
