Industrial wastewater contains residues of potential chemical wastewater, sanitary waste water, technical waste water substances. This group of compounds is generally called “micropollutants” and existing conventional wastewater treatment plants based on biological treatment are capable of degrading or removing them. As a result, they are commonly discharged into water bodies, like rivers, causing harm to the fauna and flora of these habitats. Further, these receiving water bodies are often the source of water for drinking water production plants which would similarly pass the micropollutants. Therefore, there is an urgent need to implement new chemical treatment process to further treat effluent from conventional wastewater treatment plants. Processes commonly used in wastewater treatment include phase separation (such as sedimentation), biological and chemical processes (such as oxidation) or polishing.
These are used to remove suspended solids in wastewater through aggregation, making them easier to filter out. Examples include aluminum sulfate and polyacrylamides.
Used to control and reduce foam formation in water treatment systems. They are typically silicone-based compounds.
