A Review on Enhancing the Quality of Wastewater Using Pervious Concrete Using Base Layer of Agro Waste Materials
摘要
The wastewater collected through drains may contain toxic contaminants which creates a challenging problem during its filtration and treatment. In most of the cases when runoff water gets mixed with different wastes like from ex. Garages, industries, or any source like may be physical activity of human may result into creation of wastewater and creates a trouble in the process filtration and processing of the wastewater. This study focuses on sustainable wastewater management solution by employing pervious concrete as a filtration medium and incorporating an agro-waste base layer for improved contaminant removal. The agro-waste layer is composed of available organic materials, which acts as a bio-filtration medium, accessible, and also available at a very low cost. It is being studied that the usage of agro waste material in the form of activated carbon as it is effective contaminant removal. The pervious concrete allows efficient water seepage through it, which reduces surface runoff and allows the water to interact with the bio-filtration layer which acts as an effective absorbent and leads to enhanced purification. This composite system has dual benefits i.e., effective wastewater filtration and eco-friendly utilization of agro-waste. Rice husk, coconut husk, sugarcane bagasse and corn cob are one of the biggest problems today and in the future. The study makes it clear that these wastes act as biosorbents have demonstrated good potential for the removal of various aquatic pollutant. The potential of carbonaceous wastes acts like a source of biomass material for making adsorbents for wastewater treatment is discussed in this review. This review paper also demonstrates the outstanding adsorption performance of such adsorbents, which can serve as an affordable alternative option as compared to more expensive commercial carbons. The study evaluates the filtration efficiency and pollutant reduction potential of this composite approach, which highlights its viability for sustainable wastewater treatment and the potential contribution to addressing water quality challenges.
