Degradation kinetics of organic matter in dairy industry wastewater by flotation/ozonation processes

Investigating the efficiency of chemical coagulation/Electro-Fenton process in the removal of organic matter from pharmaceutical industry wastewater

Background and Objective: Wastewater from pharmaceutical industry has high chemical oxygen demand as a result of the presence of organic drugs and antibiotics. In order to meet the environmental requirements, several treatment methods like chemical and electrochemical methods have been widely applied due to their high ability to remove organic compounds from pharmaceutical wastewater. Therefore...

degradation of organic matter of municipal sewage sludge using ultrasound treatment in shiraz wastewater treatment plant

results the results of this study showed that the release of soluble chemical oxygen demand (scod) in the supernatant and srf were in the range of 127.9-831 mg/l and 12.48-36.55 m/kg at 10 to 120 min ultrasonic contact time, respectively. in addition, ts and vs decreased from 57.98 and 56.31 to 52.69 and 49.87 mg/l, respectively. despite the significant reduction in the solids, there was no con...

Experimental Design to Optimize Degradation of Organic Compounds in Wastewater from Semiconductor Industry Using Fenton Reagent

The aim of this work was to study the possibility of treating an industrial semiconductor wastewater by combining physical and chemical methods. The combined treatment consisted of pH adjustment to 2 followed by filtration and then chemical oxidation with Fenton reagent over the resulting filtered wastewater. In chemical oxidation treatment, the isolated effect of the variables on the degradati...

Sorption, degradation and leaching of pesticides in soils amended with organic matter: A review

The use of pesticides in modern agriculture is unavoidable because they are required to control weeds. Pesticides are poisonous; hence, they are dangerous if misused. Understanding the fate of pesticides will be useful to use them safely. Therefore, contaminations of water and soil resources could be avoided. The fates of pesticides in soils are influenced by their sorption, decomposition and m...
