Capturing the water purification potential of SolarSack

Niveau:Masters, Bachelor

SolarSack helps bring safe drinking water to low-income communities with a simple water purification technology called solar water disinfection (SODIS), using the UV and heat from the sun to kill disease-causing microorganisms in the water.

A key goal in our testing is to make sure that SolarSack works in all the places where it is implemented. In order to capture the full performance potential of SolarSack we need to test and analyze the purification effect by SolarSack under different environmental conditions simulating real use scenarios.
We are looking for a student to carry out such testing and help expand our knowledge of critical environmental factors by utilizing microbiological technologies and data modelling.  
The project will be focused on testing SolarSack performance against the model organism Escherichia coli under simulated environmental conditions such as temperature, solar irradiance, and different important water parameters, and will include:

  • Experimental design
  • Microbiological assays and analysis methods
  • Data modelling

According to the World Health Organization (WHO), 2.2 billion people do not have access to safe drinking water leading to sickness and deaths. The current methods of boiling contaminated water using wood fuel leads to a significant increase in CO2 emission and deforestation.  
SolarSack is the only non-chemical water purification solution that is affordable for low-income communities. So, if you are looking to make an impact while doing your thesis work SolarSack could be the right place for you.  

We are also open for interns and smaller projects in form of special projects or similar.
Feel free to reach out to Charlotte F. Michelsen ( if you have any questions.

We expect the student to have basic biological understanding and laboratory experience. Experience with data modelling tools is a plus.
