treatment of magnetite tailings

Biological Wastewater Treatment

We also offer key innovations for simultaneous nitrification denitrification, magnetite ballasted treatment and nutrient removal. In addition, when plant treatment equipment reaches the end of their useful life, Evoqua can help turn what you have into what you need, to increase performance, reduce maintenance, and extend lifetime to keep treatment plants up and running.
