Real-time monitoring method to monitor the disinfection of conventional drinking water treatment processes of small islands

Country: Greece

Location: Mytilene, Lesvos

Start Date:

Duration: 3 months

Organization: University of the Aegean,  

Description of the organization :

The University of the Aegean (UAEG) has been founded on six different islands in the Aegean Sea and includes 18 Departments (https://www1.aegean.gr/aegean2/index.html).

 The Marine Science Department (DMS) supports academic activities in the fields of earth system science, oceanography and marine biosciences. Ourania Tzoraki is member of the Coastal Morphodynamics-Management and Marine Geology Laboratory of the DMS, which focus on the study of the river basin and the coastal zone, with its main aims being the education/training of undergraduate and postgraduate students in basic and applied research. Main research directions are the river hydrology, water safety, the impacts of climate change on the water resources and the river restoration. The nature of the river basin and coastal processes requires interdisciplinary approaches and cooperation with the other academic staff of the DMS and the Department of Geography as well as with scientists from academic institutions in Greece and abroad.

Description of the Internship :

In small islands in borderland, such as Mytilene municipality  (Greece) is missing the adequate technical personnel and knowledge to proceed in effective drinking water treatment. Chlorination is necessary to prevent epidemics of waterborne disease however, excess chlorination is wasteful, produces harmful disinfection byproducts, exacerbates corrosion and causes deterioration in aesthetic qualities, leading to consumer complaints. Residual chlorine must be continuously monitored to prevent both under- and over-chlorination and factors including pH, temperature and fouling must be considered as these also affect the disinfectant strength of residual chlorine. 

Recently sensors have been installed in Mytilene to monitor in real-time residual chlorine. The objective of this internship is the processing of the “residual chlorine” sensors data, the analysis of the drinking water network of the town and the development of an algorithm that will allow the use of sensors as a Real-time monitoring method.

Profile of the Intern :

Strong programming Knowledge. Knowledge of water quality chemistry is essential.

Accommodation provided : No

Meals provided : No, but access to university restaurant that offers (breakfast, meal and dinner with total cost of 3 euros)

Other comments : The student could also apply for Erasmus+ mobility and to cover with that way some of the accommodation costs.
