How are industrial effluents treated?
Methods include advanced oxidation processing, distillation, adsorption, ozonation, vitrification, incineration, chemical immobilisation or landfill disposal.

Why is effluent a problem?
The addition of nutrients to water commonly results in rapid growth of weeds and algae, which can then lead to further loss of oxygen as the plants die and decompose. When effluent is continually discharged to a waterway, the water quality can deteriorate to a degree that most dissolved oxygen is removed.
