Abstract

Water is essential for life. Many of the countries across the globe that have poor management of potable water resources and lack critical infrastructure for managing wastewater. As the population of the Earth grows exponentially, the demand for water increases. More than 1 billion people across the world do not have access to potable water and they are struggling with epidemic level disease outbreaks, limited water supply among other large-scale public health risks. Large-scale critical infrastructure chains are required in order to produce potable water from raw water sources, and developing countries continue to struggle economically and cannot afford the same treatment chains as the developed world. This research project evaluated the feasibility of two photocatalytic and photo-Fenton solar reactors on their capabilities to breakdown water contaminants present in natural hydrosystems and freshwater resources namely rivers. The approached adopted to achieve this was the photo-Fenton reaction and solar-photochemical reactors designed constructed and tested for the removal efficiencies of Chemical Oxygen Demand (COD), ammonia, nitrates, nitrites and phosphates via LCK curvette tests, in addition to turbidity and colour. The water quality analysis and results showed that oversaturation of the photo-Fenton reagents reduces the effectiveness of the reaction, and that finding the correct chemical balance has a greater impact on the removal efficiencies of the five pollutants than the use of UV light catalyst. The difference in the reactor builds was their diameter, and the results showed that the reactor of smaller diameter achieved the best removal efficiency across all five pollutants.
