The study was complicated by the fact that Chemical Oxygen Demand (COD) was removed by growth and maintenance of active biomass and by adsorption in and on the sludge. Coloured compounds caused an inhibition effect on the anaerobic digestion of the wastewater. This inhibition, shown at low COD concentrations of diluted OOME, was due to accumulation of recalcitrant coloured compounds in the sludge, inducing irreversible inhibition of bacterial growth. Partial decolourization of OOME through resin (Duolite XAD 761) treatment reduced the toxic effect.","PeriodicalId":15303,"journal":{"name":"Journal of Chemical Technology & Biotechnology","volume":"28 1","pages":"414-420"},"PeriodicalIF":0.0,"publicationDate":"1996-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86431175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiments were performed at various temperatures and pH values, and the initial hydrogen peroxide concentration in the combined process was also varied. An Emission Model was used to evaluate the radiation flow rate absorbed by the reacting medium for each reaction time. From simple mechanisms, the rate equations for both processes were obtained. The application of the experimental data to those equations allows one to determine the quantum yields for the direct photolysis, and the kinetic constants for the reaction between Bentazone and the hydroxyl radicals generated in the combined photolysis.","PeriodicalId":15303,"journal":{"name":"Journal of Chemical Technology & Biotechnology","volume":"52 1","pages":"206-212"},"PeriodicalIF":0.0,"publicationDate":"1996-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90607200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In all cases silver, mercury, ruthenium and molybdenum inhibited bacterial growth.
