No, studies to date cannot prove that nanomaterials pose a risk to our wastewater treatment plants. But a possible cause of concern is the targeted use of nanomaterials with antibacterial properties. They could kill the bacteria in the biological treatment stages. However, the amounts of nanomaterials in the wastewater and later in the sewage treatment plant are too small to disrupt the work of the bacteria in the biological purification stage.
