12: Evaluation of nitrate contamination in ground water and sustainable solutions for its removal
12: Evaluation of nitrate contamination in ground water and sustainable solutions for its removal
Groundwater is an essential and indispensable resource that meets the dire needs for drinking and irrigation purposes. Different sources such as industrial, municipal, urban, and agricultural runoff are the main contributors to water pollution. Nitrate, an inorganic form of nitrogen, one of the water pollutants, can destroy water quality ecologically and clinically by causing eutrophication in aquatic bodies and methemoglobinemia (blue baby syndrome) in human infants, and other health complications in animals. According to the Nitrate Pollution Index (NPI), it is essential to regularly monitor well sites to prevent nitrate contamination resulting from human activities, including waste disposal in open areas and sewage infiltration. By testing groundwater samples through spectrophotometry, this study aims to understand the extent of nitrate contamination and develop a practical and sustainable solution for its removal. We perform a comparative analysis of filtration efficiency using two treatment combinations: activated charcoal with Chlorella vulgaris and activated charcoal with duckweed. These combinations are layered in a column chromatography setup to enhance the filtration process. This study aims to determine the most effective and environmentally sustainable method for nitrate removal, contributing to the development of scalable water treatment solutions for regions facing similar contamination challenges
26: Efficiency of Bio Adsorbents In The Removal Of Heavy Metals From Waste Water
26: Efficiency of Bio Adsorbents In The Removal Of Heavy Metals From Waste Water
Industrial pollution of wastewater due to heavy metals poses significant environmental and health risks as these toxic substances contaminate water sources, disrupt ecosystems, and threaten human well-being. The River Periyar, particularly in the Eloor-Edayar industrial belt, has been a subject of pollution studies for many years and has been reported to have a poor water quality index due to high levels of heavy metals, including iron. Excess iron in water bodies affects aquatic life and water usability, making its removal essential for environmental sustainability.This study explores the use of brewed tea waste as a low cost and eco friendly adsorbent for removing iron from surface water collected from the Periyar River stretch near Edayar Bridge. Tea waste is an abundant and biodegradable agricultural byproduct with strong adsorption properties due to activation by heating which facilitate metal binding. The research focuses on understanding how different factors influence the iron removal process, including the amount of adsorbent used, temperature, contact time, and stirring time. These parameters play a crucial role in optimizing the adsorption efficiency of tea waste.To analyze the effectiveness of tea waste, the study uses a Scanning Electron Microscope (SEM) to examine the surface morphology of the adsorbent before and after iron adsorption. Additionally, a UV-Vis spectrophotometer is employed to measure the absorbance characteristics of treated water, allowing for precise quantification of iron concentration after treatment. The findings indicate that tea waste is an effective, sustainable, and costefficient material for removing iron from contaminated water. This research highlights the potential application of waste tea as an alternative adsorbent for water purification, contributing to sustainable waste management and environmental conservation efforts.
