Mohaned Sousi from Palestine is currently conducting his PhD research at IHE Delft, Institute for Water Education, at Environmental Engineering and Water Technology Department. Since he started his PhD journey in November 2014, Mohaned is focusing on assessing biological stability of drinking water produced with different water treatment technologies, with a great focus on reverse osmosis and remineralization treatment.
Mohaned has obtained his BSc degree in civil engineering in 2010 from Gaza university, Palestine. Later in 2013, he completed his MSc study with distinction in Water Supply Engineering at IHE Delft, Institute for Water Education.
The difficult water situation in his country, Palestine, has led Mohaned to explore water field, in particular increasing his knowledge in desalination of seawater and brackish water to produce potable water to cope with the lack of fresh water resources.
TopicBiostability of drinking water
Biological stability is one of the main water quality parameters where it can be defined as the water tendency to limit the growth of the microorganisms present in the water in order to assure safe drinking water at the consumer's tap. Maintaining an acceptable biologically stable drinking water is a challenge especially in non-chlorinated water distribution systems. Thus, improving water treatment is the key solution in such situations. Reverse osmosis (RO) is an advanced water treatment technology which provides solutions for drinking water companies to produce water with very low nutrient content, and therefore, very high level of biological stability, i.e., limited bacterial growth. Moreover, Flow Cytometry (FCM) and Adenosine triphosphate (ATP) are used to monitor bacterial growth.
This PhD research is conducted in collaboration with the Dutch drinking water companies Oasen and Evides.
