Analysis of nutrient concentration in the water of the Ouled Alkayem dam in the Wilaya of Mila and Design of a Floating device for combating eutrophication

Abstract

Life would not be able to exist on Earth without water, as it is fundamental to all living organisms. Every single organism on the planet needs water to sustain life and develop. To adhere to the increasing pressure towards the environment, preserving the quality of water resources is crucial, especially when it comes clarifying the problems of water pollution and eutrophication which causes excessive algae growth in water bodies. This research aims to assess the reasons for algal bloom in the Oulad Kaïm Dam in Oued Athmania, Mila Province by evaluating the physical and chemical properties of the water in the dam. It also intends to study the impact of graphene and green clay to reduce algal bloom under test conditions. Water samplings were conducted at the dam and brought to the lab for testing, which included the following physical and chemical aspects ( Degrees of temperature Ph Conductivity Turbidity. Sulphates, Ammonium, Phosphates, Nitrites, Nitrates, and Silicon Concentration). Graphene and green clay both proved to be effective in lowering the concentrations of these substances which helps limit algal proliferation and improves the quality of water nutritionally and structurally. The materials seem to be an effective environmentally sustainable method for treating surface waters impacted by eutrophication
