The applicability of Fenton's oxidation as an advanced treatment for chemical oxygen demand (COD) and color removal from anaerobically treated poultry manure wastewater was investigated. The raw poultry manure wastewater, having a pH of 7.30 (+/-0.2) and a total COD of 12,100 (+/-910) mg/L was first treated in a 15.7 L of pilot-scale up-flow anaerobic sludge blanket (UASB) reactor. The UASB rea...

the present study investigated oil/water demulsification and treatment of oily wastewater originated from port waste reception facilities by electro coagulation using aluminum electrodes in a batch reactor. the efficiency of al electrodes in removing ss, cod, and oil & grease from wastewater with different current densities and operational times were investigated. the characteristics of th...

background: in this study, ferrate (vi) and ultraviolet (uv) radiation were employed to remove hydrogen sulfide from municipal wastewater resulting in a reduction in chemical oxygen demand (cod). although ferrate (vi) and uv have been used individually for the removal of a few pollutants from urban and industrial wastewater, there exists no study to investigate the effectiveness of simultaneous...

The application of synthetic colors in textile industries and their entry into the water and groundwater is an environmental problem because of being very toxic material. The synthetic colors which are used in textile dyeing (plyacrilic and polyester) are usually dispersing colorants. They derive the azo and anthraquinone chemicals. Electro-Fenton process is an efficient technique which can deg...

background: industrial development has caused the release of various pollutants including heavy metals into the environment. these toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. the aim of the pre...

the removal performance of total poly phenols and orthodiphenols (o-diphenols) content in olive mill waste (omw) was investigated with a three stages cross flow laboratory scale rotating biological contactor (rbc) in the present study. due to high cod and other pollutant in the original omw, physico-chemical treatment was effected for cod and other pollutant reduction prior to biological treatm...

this study investigates the degradation of sodium dodecylbenzenesulfonate (sdbs) in aqueous solution by the fenton-like oxidation process. the effects of different parameters such as concentrations of ferric chloride and hydrogen peroxide, ph and reaction time on the sdbs removal and chemical oxygen demand (cod) reduction were evaluated. response surface methodology (rsm) with central composite...
