Methane (CH4) is one of the strongest greenhouse gases. Sources CH4 are anthropogenic and natural, former playing ∼60% role. Major sink for atmospheric OH Cl radicals (originating from CFCs), biological system. Biological mediated through oxidation by specialized group bacteria called methanotrophs (MB). Methanotrophs have been reported almost all soil systems such as sediments, oceans, extremes pH, salinity, temperature. They oxidize methane aerobically in presence enzyme monooxygenase...
Abstract The purification of the primary treated domestic sewage was performed in present study through horizontal sub-surface flow constructed wetland (CW) 10 × 3.5 m dimension. using three setups CW 1 (Unplanted CW), 2 (CW planted with macrophyte Typha latifolia ), and 3 two species T. Commelina benghalensis ). experiments were by converting one type into other form sequentially, i.e., built first after experiments, it converted then 3. filled a layer coarse fine gravel 70 cm depth as...
Abstract In the present research water quality from nine different sampling points (S1–S9) River Ganga at Varanasi was examined for parameters, and multivariate statistical analyses were carried out. Subsequently, several indices, such as index Nemerow pollution (NPI), calculated. The results indicated that had high levels of coliform concentrations, altered pH, elevated dissolved oxygen/biochemical oxygen demand chemical values. weighted arithmetic values revealed sites S8, S9, S2 most...
SWINGS was a cooperation project between the European Union and India, aiming at implementing state of art low-cost technologies for treatment reuse domestic wastewater in rural areas India. The largest plant consists high-rate anaerobic system, followed by vertical horizontal subsurface flow constructed wetlands with area around 1,900 m2 final step consisting solar-driven anodic oxidation (AO) ultraviolet (UV) disinfection units allowing direct treated water. implementation operation two...
Abstract Under the present investigation, vertical subsurface flow constructed wetlands (VSSFCWs) planted with macrophytes treated domestic sewage in an environmentally sustainable manner. Treatment of is alternative method that decreases energy consumption and economic costs involved treatment environmental contaminants. This study evaluates potential efficiency VSSFCWs using two different macrophytes, Acorus calamus Canna indica for sewage. To perform this study, chambers dimensions 2.48 m...
Owing to the rapid industrial and socioeconomic development, heavy metal concentration in river is gradually increasing, it has potential threaten aquatic environment mankind. The present investigation deals with quantification fractionation of metals from sediments Narmada River. presence these can be toxic human health life, therefore different pollution indices were evaluated identify degree threat that might imposed by contaminants surface water sediment. In this context, risk assessment...
