Optimizing water purification by 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 continuous development at SolarSack is to make sure that our product can withstand the different environmental challenges it faces where it is implemented and still shows high water purification performance. One such challenge is the presence of microorganisms in source waters that can form biofilms and we are therefore testing different polymer materials for their resistance toward attachment and biofilm development by various microorganisms.

We are looking for a student to help in the development of biofilm assays for testing under various simulated environmental conditions and thus to expand our knowledge for future product optimization.  
The project will be focused on testing different SolarSack polymer materials for their resistance against attachment and biofilm development by different model microorganisms, such as green algae, cyanobacteria, and Escherichia coli, and will include:

  • Experimental design
  • Biofilm assay development and testing
  • Data analysis

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 (cm@solarsack.com) if you have any questions.

We expect the student to have basic biological understanding, experience with biofilm assays, and laboratory experience.
