Many industries generate wastewater containing metals such as copper, zinc, chromium, lead, iron and nickel. Before discharge, concentrations must be reduced below emission limits. When metals are complexed, conventional treatment such as pH adjustment to precipitate them is often insufficient.
EFA Chemie has developed speciality metal complex breakers that release metals from their complexes so they can be removed through flocculation.
Copper is often a limiting parameter in practice, but complex breakers can reduce its concentration in the filtrate to acceptable levels.
