Abstract: | This master thesis is mainly focused on the Flocculation, Fenton Process and Ozonation as a treatment process for the purification of the distillery effluent. Different treatment parameters were optimized for all three process separately as well as in the for the integration scheme. First of pH and flocculant concentration were optimized for the flocculation process. Potassium alum was used as a flocculant for the treatment of distillery effluent. The total TSS removal found was 89 % at pH 35 and 5 g/l of flocculant concentration. A very little COD removal was found in the flocculation process which requires an additional treatment method to improve the overall COD removal efficiency. Fenton process and Ozonation were basically used as an additional treatment. At the next step, pH was optimized for both ozonation and fenton process also. pH in the. acidic range gives the higher COD removal for the both fenton and ozonation process in comparison to pH in the alkaline medium. A comparative study was also made for the fenton process for raw distillery effluent and flocculated distillery effluent, from the view of COD removal fenton process of flocculated effluent can considered best but it IV does not worth the additional cost of the flocculant added. An integration experiments of Ozonation and Fenton process was also executed at the p1-I of 35 and 8, this integration gives very high COD removal in the acidic phase in comparison to alkaline phase. Fenton process followed by ozonation has shows more results for COD removal than integration of opposite sequence. At the last of this work, COD removal for combination of all three processes was compared with results coming from the previous optimized integration and found that even combination of all three methods can't be used as a whole treatment of distillery effluent due to low COD removal efficiency. So, it is must to perform a biological treatment method after this pretreatment to improve overall COD and TSS removal. |
