Vegetated buffers are a well-studied and widely used agricultural management practice for reducing nonpoint-source pollution. A wealth of literature provides experimental data on their mitigation efficacy. This paper aggregated many of these results and performed a meta-analysis to quantify the relationships between pollutant removal efficacy and buffer width, buffer slope, soil type, and veget...

carbon nanotubes (cnts) are a novel material that exhibits good adsorption behavior toward various toxic pollutants in aqueous solution. these adsorbents have a fast adsorption rate and high adsorption efficiency, efficient to remove various pollutants and they are easy to recover and reuse. these features highlight the suitability of cnts for the treatment of water polluted with heavy metal io...

As urbanization continues, water pollution is of increasing concern for human health and the environment. Water contaminants common in urban stormwater include nutrients, metals, suspended solids, pesticides, pathogens. The search an inexpensive readily available material that can effectively remove ongoing. Studies have shown woodchips are a promising many different contaminants, including the...

This work aimed to produce hydrogen (H₂) simultaneously with pollutant removal from biodiesel wastewater by photocatalytic oxidation using a thermally-treated commercial titanium dioxide (TiO₂) photocatalyst at room temperature (~30 °C) and ambient pressure. The effects of the operating conditions, including the catalyst loading level (1-6 g/L), UV light intensity (3.52-6.64 mW/cm²), initial pH...

This paper investigated the highway stormwater quality at two Texas cities-Austin and College Station. Two highways with high average daily traffic were monitored using passive stormwater samplers for collecting first-flush runoff during a 16-month period. Detailed traffic and weather data were collected at College Station sites, but only weather data were obtained at Austin sites. A stepwise r...

in the present study, photocatalytic removal of p-nitrophenol has been carried out in the presence of zno by using a batch reactor with a uv-c lamp (15 w). the effects of applied zno concentration and uv light intensity have been studied. the increase of initial pollutant concentration decreases the removal rate, and the results indicate that the apparent reaction rate constant in the uv/zno pr...

The purpose of this study was to determine whether continuous flow SBR could provide efficient pollutant removal in domestic wastewater. The experiment was carried out using a pilot scale at Tehran University of Medical Sciences and in wastewater treatment plant. The results showed that 97.7% of BOD removal, 94.9% COD removal, 85.4% TKN removal, 71.4 % TN removal, 55.9% TP removal and 99% TSS r...
