In this study the dye removal capacity of locally produced alum was investigated. The efficiency of the process was investigated in series of batch experiments using simulated textile dye solutions to assess the effects of various process parameters: contact time, alum -lime weight ratio, coagulant dosage, dye's initial concentration, pH and reaction kinetics of coagulation. The result of the study showed that an increase in both coagulant dosage and dye initial concentration increases the percentage of dye removal. In all cases the percentage of dye removal at optimized conditions is nearly or above 90%. Most of the reactions are completed in less than 20 minutes. The highest percentage of the dye removal was observed at pH around neutrality for all the dyes indicating that addition of lime is indispensable to maintain efficient floc formation. The reaction kinetics of Indantrene Brown and Imperon Orange was observed to obey pseudo first order kinetics, with rate constants k1 = 0.055 min-1 and k2 = 0.114 min-1 for Indantrene Brown and Imperon Orange, respectively. It was found that alum combined with lime is suitable material for removing dyes from wastewaters.","PeriodicalId":245987,"journal":{"name":"Sinet, Ethiopian Journal of Science","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127066278","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}
