Water Treatment for selenium, Boron and Heavy Metals, Smelting, Ontario

A refinery in Ontario was confronted with a difficult wastewater treatment challenge, dealing with effluent from wet scrubbing of flue gas featuring concentrations of 100 mg/L for hexavalent selenium. The refinery enlisted the expertise of an independent engineering firm for an initial assessment. Following this assessment, ZeViron™ was selected for testing. Wastewater samples from the refinery were tested in LaFar’s laboratory in Richmond. ZeViron™ demonstrated rapid selenium removal to levels below 0.002 mg/L, showcasing remarkable efficiency.

Continuous pilot demonstration testing further affirmed ZeViron’s effectiveness, achieving target treatment concentrations even with a challenging 100 mg/L influent selenium concentration. The treatment not only met selenium targets but also resulted in complete removal of other heavy metals including chromium, molybdenum, antimony, copper, etc.

Remarkably, the treatment residue passed the TCLP test, signifying its suitability for landfill disposal.
