My study investigated the feasibility of a bio-flocculant as an accessible, safe, affordable and environmentally friendly option to reduce turbidity. Using a combination of dried lemon peel and chitosan, I tested different concentrations to find the optimal dosages to reduce turbidity. The bio-flocculant identified offered an affordable treatment option for those with limited access to clean water while being environmentally friendly and offering no adverse health effects sometimes associated with flocculation.
This study looked at potential bio-waste adsorbents to decrease the phosphate run-off into natural waterways from agricultural fertilisers and animal manures.
Identifying eggshell waste as an effective adsorbent for phosphate, a mathematical model and website were developed for farmers to calculate cost savings and application rates of eggshell on their soils. This free and accessible tool will be available to help farmers counteract their environmental footprint.
A new, novel and innovative ultraviolet radiation sticker has been developed to accurately measure large UV exposures for Solar Disinfection of water. The SODIS Sticker is capable of accurately measuring the solar UV exposure required to sanitise drinking water through 2 innovative products built together. A high accuracy and transparent UV sensitive film coupled with a partial UV blocking filter, was used to construct The SODIS Sticker.
