Heavy metals in industrial wastewater: hazardous waste or secondary resource?

Not long ago on the blog, we have talked about natural groundwater quality triggered by geogenic factors and related hazards such as a high concentration of heavy metals. Today’s topic concerns the anthropogenic input of heavy metals into the water and how to solve its impact effectively.  Industrial processes can lead to heavy metal bearing wastewater, which is commonly treated by inefficient purification methods. Therefore, it is time to think about alternative methods for recovering the metals that would otherwise pollute the water and create a hazard for the environment. In addition, the obtainable metal resources make their recovery attractive from an economic point of view. However, efficient removal and recovery of toxic metals from industrial wastewater streams is a major challenge. To understand better the subject and the potentiality of specific water’s treatments, we interviewed two PhD students, Kai Tandon and Iphigenia Anagnostopoulos, both working in the group of Prof. Dr. Soraya Heuss-Aßbichler at LMU Munich.
