Study of Groundwater and Surface Water Remediation
Abstract: Groundwater remediation is the process of treating contaminated groundwater by removing contaminants or converting them to harmless chemicals. Water that saturates the pore space in the subsurface and is located beneath the ground surface is known as groundwater. Between 25% and 40% of the world's drinking water comes from boreholes and dug wells. Farmers need groundwater to irrigate crops, while industry use it to make everyday items. Even though most …

Study of Heavy Metal ion adsorption from Synthetic Wastewater with the help of biomass and analysis of Mathematical Model
Abstract: The biofilm matrix is a mixture of secreted polymers, metabolites and nutrients ingested, lysis solution products, and even particle debris. This matrix, which is polyanionic by nature, is essential for the activated carbon of metal cations. In this study, the heavy metal adsorption mechanism in biofilms is modelled in one spatial dimension. The numerical method is a free-boundary value issue for nonlinear parabolic and quadratic partial differential equations. Parabolic equations …

Study on Compressive Strength of Concrete by Partial Replacement of Cement with Metakaolin
Abstract: Concrete is that the most typically used material for construction. The worldwide production of cement has greatly inflated since 1990. Production of cement leads to heaps of environmental pollution because it involves the emission of CO2 gas. Supplementary building material materials (SCM) area unit finely ground solid materials that area unit accustomed replace a little of the cement in a very concrete mixture. These supplementary materials could also be present, …

Treatment of CO2+NH3 Mixed Waste Gas from Different Sources by Blend Solvents
Abstract: The waste gas from chemical plants, including urea fertilizer plant, contains a large amount of CO2 gas in addition to NH3 gas. New solvents have been studied for use in the absorption of waste gases, but most of them are carried out at specific compositions and flow rates for individual gases. In this paper, a complete conceptual design of the process for separately absorbing CO2 and NH3 gases in a …

Fast Lanes by Design: Quantifying RFID Electronic Tolling Impacts on Plaza Halt Times in Highway
Abstract: Abstract—Rapid urban growth and the steady rise in the number of vehicles have made congestion at highway toll plazas a persistent and costly problem. Long queues at toll booths not only waste travelers’ time but also increase fuel consumption, air pollution, and overall operating costs of the transport system. Traditional manual toll collection methods contribute significantly to these delays, as vehicles are required to stop for cash or card-based transactions. …
