When deciding on a topic, I was instantly drawn towards the process of water purification and the possible experiments that I could conduct. I always had an interest in the topic and the EE seemed like a good opportunity for me to explore the topic through a subject that I was passionate about. Originally, the plan for the experiment was to use alum and durian seed starch and compare the coagulation of each under different PH levels. Through further research, however, it was found that durian seed starch may not work as expected under the PH levels chosen as well as problems when measuring the turbidity of the solution (due to the fineness of the starch). The experiment may also utilize either a colourimeter or a spectrophotometer to see how effective coagulation was though this will have to be further experimented with in the future.
