Automated Regulation of Aquaculture Water Quality Using Sensors and Natural Filtration Techniques

Water quality analysis using key parameters such as turbidity, temperature, and pH is crucial for maintaining a healthy aquatic environment in aquaculture systems. This paper proposes an automated mechanism to monitor and regulate these parameters using environmental treatment cues, including calcium carbonate, sand filters, charcoal filters, zeolite, and ethylene glycol. Specifically, calcium carbonate is used to stabilize pH, ethylene glycol regulates temperature, and a combination of sand, charcoal, and zeolite filters is employed to reduce turbidity. Once the threshold levels of pH, temperature, and turbidity are assessed, water is treated sequentially through these mediums to ensure optimal conditions. This method is both cost-effective and automated, offering practical benefits for aquaculture applications. The paper also presents an experimental setup for turbidity sensing and includes a comparative analysis between the obtained experimental results and the optimal values recommended for various fish species under the proposed methodology.
