The SoWaDis-Project in SEKUCo

Sebastian Kolowa University College (SEKUCo) has engaged in scientific study by cooperating with Institute for Solar Technologies (SPF) in Rapperswil to develop a solar thermal system to disinfect drinking water.

SEKUCo believes that modern countries have the benefits of having high quality choices when it comes to disinfect the public water supply. But what can small communities in the developing countries do to have a water treatment plant to properly disinfect their water supply.

Due to that cooperation the scientific study testing was established by installing a vacuum glass that will boil and disinfect water. The implementation was led by Dr. Elimar Frank with his fellow in partnership with SEKUCo.

The contaminated water is stored around two meters above ground because the system is gravity driven

SEKUCo intends the following befits to college students and the community at large:

  • The improvement of the microbiological quality of drinking water
  • Using solar UV-A radiation and temperature to inactivate pathogens causing diarrhea
  • Used at household level under the responsibility of the individual user
  • Replicable with very low investment costs
  • Environmental friendly source of energy to disinfect water.

SPF claims the costs of the developed system are comparable to other water disinfection technologies. The overall, the goal of the project it improves the sanitary standard by providing clean drinking water in developing countries.

Water is flowing under the simple stages:

  • The contaminated water is stored around two meters above ground. The system is gravity driven, therefore operating without a pump using electricity.
  • The contaminated water flows into the heat-ex- changer and gets preheated from around 20°C to65°C.
  • The preheated water flows into the solar collector.
  • In the collector the water is heated up to 82°C.This is the process where the water is thermally disinfected.
  • A thermostatic valve on the collector’s outlet opens when 82°C are reached. When the temperature drops below it is closing again.
  • The disinfected water flows through the heat ex- changer, cooling down from 82°C to around 35°C and preheating the collector’s inlet.
  • Finally the disinfected water flows into the water storage.

However SEKUCo wish the surrounding communities academician and local people to invest on the technology to reduce diseases that are mainly caused by drinking contaminated water.

SEKUCo propose priorities of the Engineering faculty in future that the implemented SoWaDis project encourage the development of applied research in engineering fields of special significance to the SEKUCo student and Nation at Large.

With the establishment of the new Faculty of Science in Eco-tourism & Nature Conservation a few months ago, there is a great new initiative in that area. The new faculty has solutions in environmental problems that needed to be resolved. This will be the critical area for the University to take a lead nationally in its intellectual, academic and research contribution to national development.
