Partnership Summary
Micropollutants are small, harmful, and prevalent. The common usage of drugs like painkillers, anti-inflammatories and other chemicals like organic dyes leads to an increased concentration of these compounds in wastewater. In addition to medication (e.g. diclofenac), micropollutants derive from pesticides, industry chemicals and much more. To date, wastewater treatment plants cannot filter out these compounds efficiently. This causes rising concentrations of environmentally harmful substances in the waters around treatment plants, directly resulting in increased mortality of zebra mussels and acid burns on cornea of trout. As a result, many fish species have become extinct, with many more to be impacted if no intervention occurs.
But three iGEM teams are focused on solving this problem by utilizing laccases. We are from Darmstadt, Kaiserslautern, and Stuttgart and all of us see these micropollutants as a huge problem impacting our planet. In this Partnership webpage you can find a comparison of our three projects and useful literature recommendations or expert excerpts from interviews we’ve conducted. We would be glad if we inspire you to improve our projects in future endeavors and help you with our advice.
To get a good entry into the field of wastewater treatment the picture explains the current steps of a typical wastewater treatment in Germany. Most of these steps are the same in different countries, which you can see in our comparison of the wastewater meetings with other countries. Just hover your mouse over each tank and discover the structure of sewage treatment plants.
Stage | System | Explanation |
---|---|---|
Mechanical Treatment Stage | Intake Drain (inlet) | Wastewater enters the treatment plant. |
Mechanical Treatment Stage | Rake | large solids. |
Mechanical Treatment Stage | Sand Trap | Wastewater is slowed down to enable remaining debris to drop to the bottom of the tank. |
Mechanical Treatment Stage | Grease Trap | Grease is filtered out. |
Mechanical Treatment Stage | Primary Clarifier | In the initial clarifier, all solids that did not fall out in the previous tanks are separated. Water is held here for several hours in order to skim off materials floating at the top. Materials at the bottom of the clarifier are collected by scrapers and pumped off. |
Biological Treatment Stage | Activated Sludge Basin | In this basin an artificial environment is created where biologically useful microorganisms can thrive. Herein temperature, oxygen levels, and contact time are controlled, enabling microorganisms to convert remaining organic waste into CO2. |
Biological Treatment Stage | Secondary Sedimentation Basin | Here microorganisms can convert the remaining dissolved solids into suspended solids that fall out of solution. |
Other | Grease | Collected grease. |
Other | Primary Sludge | Collected sludge containing an excess of water. |
Other | Sand | Collected sand. |
Other | Screenings | Collected large solids. |
Other | Thickener | Reduces water in sludge. |
Other | Return Flow | Here the microorganisms flow back to the biological step. Without this step, organism concentration in the Activated Sludge Basin would drop too low. |
Other | Raw Sludge | Sludge with lower water composition than in primary sludge. |
Other | Digestion Tower | Large tower where biogas is collected. |
