Groundwater pollution has become a worrisome phenomenon, mainly for aquifers underlying industrialized areas. In order to evaluate the risk of pollution, a model of the aquifer is needed. Herewith, we describe a quasi-tridimensional model, which we applied to a multilayered aquifer where a phreatic aquifer was coupled to a confined one by means of an aquitard. This hydrogeological scheme is oft...

Solar distillation is very much effective for availing drinkable pot water, especially in desert areas and salt-producing areas. A Still a device that can be used to convert impure (saline) water into fresh drinking using the process of Distillation. The energy source sunlight thus it uses renewable energy. This paper describes set equations find distillate yield solar still by taking input par...

Fe3+ is essential for human physiological function. However, excess amounts of are dangerous. Metal-organic frameworks (MOFs) with high porosity, stability, and facile tunability promising adsorption environmental applications. In this study, we show that thiol-functionalized Zr-MOFs can remove the highest capacity (481 mg g−1) fastest kinetics (1.07 g mg−1 h−1) reported so far, to best our kno...

Residential water demand is a function of several factors, some of which are within the control of water utilities (e.g., price, water restrictions, rebate programs) and some of which are not (e.g., climate and weather, demographic characteristics). In this study of Aurora, Colorado, factors influencing residential water demand are reviewed during a turbulent drought period (2000-2005). Finding...

Overall lockdown limitations toward the start of year 2020 are credited to annihilation and fatalities worldwide because COVID-19. Most nations revealed rapid growth COVID-19 cases subsequently declared in several stages. Because these lockdowns, industries had stop producing goods other than actual merchandise needed survive. The air quality natural water witnessed a noticeable improvement fro...

iran is one of the most energy-rich countries subsidizing energy carriers, especially in the agricultural sector, to the extent that the resulting growth is at the expense of the environment. this study tries to investigate the potential impacts of energy price reform on the agro-environment, based on the marginal abatement costs (macs) of emissions. firstly, the energy demand function of the a...

abstract some issues such as dehydration, local and chronological disproportion of rainfall, low productivity of water in agricultural sector, increasing demand for agricultural products due to increase in population participate with doughtiness are the most challenges of agricultural water. these factors caused water to be as one of the important and scarce inputs is agricultural products. the...
