Microplastic Filtration from Waste Water Using Silica

Abstract

Microplastic contamination in wastewater poses significant environmental and health risks, particularly when treated water is used for irrigation. This study explores the efficiency of silica as a filtration medium for removing microplastics from wastewater and assesses the suitability of the treated water for irrigation. Various silica-based filtration techniques were analyzed, considering factors such as particle size, adsorption capacity, and filtration efficiency. The effectiveness of silica in reducing microplastic concentration was evaluated using microscopic and spectroscopic analyses. Additionally, physicochemical parameters of the treated water, including pH, turbidity, and nutrient content, were assessed to determine its impact on soil and plant health. The results indicate that silica-based filtration can effectively reduce microplastic levels, making the treated water safer for irrigation while maintaining essential nutrients. This study highlights the potential of silica as a cost-effective and sustainable solution for microplastic removal in wastewater treatment.
