Rivers can be contaminated with different pollutants such as trout farms. Evaluation of the effect of trout farm on water quality is important to give new permission for trout farm construction. In current work, the effect of constructed trout farms near the Deinachal River on some physicochemical properties namely chemical oxygen demand (COD), biological oxygen demand (BOD5), dissolved oxygen ...

Background & Aims of the Study: The most important compounds in hospital wastewater are antibiotics, disinfectants, anesthetics, radioactive elements, static cytotoxic agents, other chemicals and hazardous materials that caused to be different domestic sewage. The purpose of this study was the evaluation of performance of extended aeration biological system in pollutants remova...

Microbial fuel cell represents an emerging technology to attain electrical energy from wastewater. There are several alternative methods available for wastewater treatment; Microbial fuel cell is one of them, which generates green energy from wastewater for making a contribution to renewable sources of energy. This study states the performance of microbial fuel cell with different parameters i....

In this study, the Fenton process was used to investigate the color removal efficiency of Acid Red 52 and Basic Red 18 dye solutions by direct chemical oxidation. Color and chemical oxygen demand (COD) was successfully removed more than 99% and up to 92% respectively. This article would provide an easy assessment of the viability of using Fenton reagent in acidic conditions, so it is a prom...

degradation of o,o-dimethyl -o-4-nitrophenylphosphorothioate (methylparathion) by ozonation in aqueous solution was studied in a batch reactor under constant ozone dosage and variable ph conditions. the effectiveness of the process was estimated based on the degree of cod (chemical oxygen demand) reduction and conversion of methylparathion. it was observed that ozonation is more effective at al...

A submerged biological filter packed with clayey schists from brick industrial waste as support material was used to treat landfill leachate. The pilot-scale plant consisted of two separated reactors, running in aerated and non-aerated conditions respectively. The leachate was taken from a landfill in Granada (southeast Spain) and was considered as partially stabilized with average chemical oxy...

The present investigation provides data on physico-chemical parameters, some major ions and nutrients on water samples of Tinishu Akaki River (TAR), Ethiopia. The pH, temperature, electrical conductivity, total dissolved solids (TDS), dissolved oxygen (DO), chemical oxygen demand (COD), biological oxygen demand (BOD), Ca2+, Mg2+, HCO3-, SO42-, NO3-, NO2-, PO43-, Cland NH3 have been determined t...

Research shows that chloride ion in the process of chemical oxygen demand (COD) analysis has a huge impact on results analysis, How to improve accuracy presence chlorine interference is difficult problem current environmental monitoring work, This article introduces different method influence degree (COD).

Attention has been paid to bioflocculants production because of their effectiveness, innocuousness and environmental friendliness. This study aimed characterise a bioflocculant from Bacillus megaterium BMBF apply it in wastewater treatment. The proteins, carbohydrates uronic acid were calculated using the Bradford, phenol–sulphuric carbazole assays, respectively. An energy-dispersive X-ray (EDX...
