The hemipteran (Insecta) diversity in the upper part of the Kerian River Basin was low with only 8 families and 16 genera recorded at 4 study sites from 3 rivers. Water bug composition varied among sampling sites (Kruskal-Wallis χ (2) = 0.00, p<0.05) but was not affected by wet-dry seasons (Z = 0.00, p>0.05). All recorded water parameters were weakly associated with generic abundance but the bi...

The quest for an effective alternative means for effluent treatment is a major concern of the modern-day scientist. Fungi have been attracting a growing interest for the biological treatment of industrial wastewater. In this study, Saccharomycescerevisiae and Torulasporadelbrueckii were isolated from spoiled watermelon and inoculated into different concentrations of effluent. The inoculants wer...

The development of a real-time monitoring tool for the estimation of water quality is essential for efficient management of river pollution in urban areas. The Gap River in Korea is a typical urban river, which is affected by the effluent of a wastewater treatment plant (WWTP) and various anthropogenic activities. In this study, fluorescence excitation-emission matrices (EEM) with parallel fact...

textile wastewater contains substantial pollution loads in terms of chemical oxygen demand (cod), biological oxygen demand (bod), total suspended solids (tss), total dissolved solids (tds) and heavy metals. phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (amats) is well established environmental protective technique. a lab scale stud...

background: soluble microbial products (smps) have an effective role on fouling of membrane in bioreactors (mbrs). the aim of this study was to survey the role of smps on mbrs used in treating municipal wastewater. materials: lowry and phenol sulfuric acid methods were used to measure carbohydrates concentrations and protein content, respectively. biochemical oxygen demand (bod), chemical oxyge...

The paper describes linear and nonlinear modeling of the wastewater data for the performance evaluation of an up-flow anaerobic sludge blanket (UASB) reactor based wastewater treatment plant (WWTP). Partial least squares regression (PLSR), multivariate polynomial regression (MPR) and artificial neural networks (ANNs) modeling methods were applied to predict the levels of biochemical oxygen dema...

A study was undertaken to assess the characteristics, like physical and chemical analysis, of wastewater Kalaburagi City. The characteristics are analysis total solids, suspended dissolved oxygen, biological oxygen demand, phosphates, nitrates. present shows that domestic is organic in nature, having average values BOD 380 mg/l, COD 510 solids 3200 2000 chloride 220 1200 mg/l.

Biochemical oxygen demand (BOD) is a widely used parameter to assess the organic pollution in water systems. This parameter can be detected by the amount of oxygen consumed via microorganisms in aerobic metabolism of organic matter present in the water. The authorized test to analyze biodegradable organic compounds is given by the American Public Health Association Standard Method Committee tha...

Demand for online and real-time measurements techniques to meet environmental regulation and treatment compliance are increasing. However the conventional techniques, which involve scheduled sampling and chemical analysis can be expensive and time consuming. Therefore cheaper and faster alternatives to monitor wastewater characteristics are required as alternatives to conventional methods. This...

This study aimed at monitoring the changes of fluorescent components in wastewater samples from 22 Korean biological wastewater treatment plants and exploring their prediction capabilities for total organic carbon (TOC), dissolved organic carbon (DOC), biochemical oxygen demand (BOD), chemical oxygen demand (COD), and the biodegradability of the wastewater using an optical sensing technique bas...
