The importance of anaerobic ammonium oxidation (anammox) – a metabolic pathway that can generate dinitrogen – remains poorly understood in freshwater river system. Using the 15N-isotope pairing technique (15N IPT) combined with membrane inlet mass spectrometry (MIMS), the potential rates of...

This study evaluated the effectiveness of solar Photo-Fenton’s technique (H2O2/Fe2+/Solar) to treat the refinery wastewater. The experimental data were analyzed using the first and second-order kinetic models. The results clearly indicated that the pseudo-second-order models gave better prediction...

The problem of reducing CO2 emissions from transport, a major contributor to the greenhouse effect, has become a growing concern for the scientific community and various international committees monitoring climate change. Energy savings in the transport sector are a key factor towards rational...

Disinfection by-products (DBPs) can be controlled by using alternative disinfectants to chlorine, removing DBPs precursors prior to chlorination and removing DBPs after formed. Chloramine is widely used as an alternative disinfectant to chlorine usage. In this study to evaluate trihalomethanes (THMs...

This study was conducted to investigate the recycling of rural wastes employing vermicomposting technology by Eisenia fetida. Three medium including kitchen waste, rotting foliage and cow dung were performed in 20 treatments. Results showed that in all 20 treatments the quality of produced compost...

In recent years children’s head hair is a biomarker frequently used for monitoring environmental exposure to heavy metals. Blood, plasma, urine and other tissues analysis were the most popular approaches to evaluate the concentrations of trace elements in human body. However, hair sample is easily...

The purpose of the study was to improve drinking water quality of conventional treatment processes by combining with UF-membrane systems. Performances of two membrane systems were evaluated in two different full-scale conventional water treatment plants in Istanbul. Low-pressure UF membranes were...

One of the fundamental carotenoid compounds available in microalga Chlorella pyrenoidosa is lutein, which is a commercially valuable antioxidant compound. The extraction of lutein from C. pyrenoidosa was studied in detail under various operating conditions. Acid pretreatment was done using 10% HCl...

The slag generated in the rotary furnaces is classified hazardous waste. In this regard, landfill disposal of lead smelting slag is not feasible since a few hundred tons are produced per year; leaching of heavy metals into ground water is of concern. The release of heavy metals into the environment...

Accessing temporal trend of different meteorological parameters is essential for understanding the local climate changing pattern of a region. Quantitative estimates of the effect of climate change helps in understanding, planning, and management of water resources systems. In this study, monthly...
