Building an AI-enhanced organic island with Brassica juncea seeds to counter eutrophication

Abstract

Decontaminating water bodies has always been a problem in terms of developing and maintaining solutions. Our eutrophication solution is an organic island made of coconut husk(Cocos nucifera) and Indian Mustard(Brassica juncea) plants. It uses remediation techniques, such as phytoremediation and adsorption. Eutrophication primarily stems from human-induced causes such as poor sewage treatment and fertilizer overuse, which results in excess phosphate and nitrate ions accumulating in water bodies. This can have severe consequences, including algal bloom, and a reduction in aquaculture. Our investigation was done over a 21-day period, during which the concentration of phosphate ions was reduced, alleviating one factor that causes eutrophication. There were 3 tanks (A, B, and C): A contained the island and the plants, B contained only the island, and C was a control that contained neither. A Phosphate ion water testing kit was used to measure phosphate ion concentration in the sample contaminated water over a 21 day period. Each phosphate ion test produced a color of a different wavelength. Using a Vernier colorimeter, the percentage of transmittance was measured for each trial. Using the Beer-Lambert Law, the concentration values were obtained, which supported our hypothesis: A and B experienced a substantial increase in transmittance levels, whereas C experienced no change. The Pearson correlation test showed a positive correlation, hence phosphate ions were absorbed at a constant rate. Our solution also uses AI (Bellman equation) to analyze regions with the greatest phosphate ion concentration, where sensors and motors are present for maneuverability.
