Removal of Organic Compounds from Municipal Wastewater by Immobilized Biomass
Two porous ceramic carriers (internal active surface 0.04 m2 for carrier I and 0.2 m2 for carrier II) with immobilized activated sludge were the stationary filling of the reactors. Municipal wastewater was treated at hydraulic retention time (HRT) from 70 to 15 min. The efficiency of organic compounds removal from wastewater changed for reactor I from 85.2 to 93.8%, for reactor II from 62.9 to ...

Enzymatic approach to phenol removal from wastewater using peroxidases
Introduction Phenol and its derivatives are present in various industrial effluents and possess a high level of toxicity even at minute concentrations. This could cause serious ecological problems if phenol-containing effluents are discharged untreated or partially treated into water bodies or land sites. Method Conventional wastewater phenol removal methods, which include biological treatment,...
متن کاملHydrogen sulfide and organic compounds removal in municipal wastewater using ferrate (VI) and ultraviolet radiation
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 si...
متن کاملMANAGEMENT of PHOSPHORUS REMOVAL in MUNICIPAL WASTEWATER TREATMENT PLANTS
As a result of uncontrolled discharge of wastewaters containing high levels of phosphorus to the receiving bodies could create adverse effects on water quality. Therefore phosphorus should be eliminated prior to discharging into aquatic environment together with carbon and nitrogen to reduce eutrophication risk. Control of effluent phosphorus level by enhanced biological methods became a standa...
