Rezumat | ||||||
Brewing industry is water intensive and consequently generates huge volumes of wastes. Bottle washing and brewing operations recognized as the major effluent sources of Asmara Brewery Corporation Share Company (ABCSC), Eritrea. Effluents of bottle cleaning and brewing sections and their mix of 2:1 characterized on weekly basis for the resemblance of national and international effluent standards. DO levels of wastes detected as low as 2.14 mg/L, which does not support any life and eventually poses severe environmental issues. TSS, COD and BOD5 levels have exceeded EU and EPA effluents standards. COD and BOD5 concentrations estimated were higher than other reported breweries and beyond the benchmarks of Brewer’s Association, USA. Brewery wastewater has a mean COD of 83240 mg/L and BOD5 of 11066 mg/L and highly contaminated than bottle cleaning and mixed effluents. Therefore, in order to reuse voluminous wastewater and to curb excessive COD levels, effluents from ABCSC require special attention prior to their discharge into the public sewer line. |

Spălarea sticlelor și operațiunile de fabricare a berii sunt recunoscute ca surse majore de efluent ale Asmara Brewery Corporation Share Company (ABCSC), Eritreea. Efluenții secțiilor de curățare a sticlelor și de preparare a berii și amestecul lor de 2:1 sunt caracterizați săptămânal privitor la corespunderea lor standardelor naționale și internaționale pentru efluenți. Nivelurile de DO ale deșeurilor detectate variază până la 2,14 mg/L, ceea ce nu susține nicio formă de viață și în cele din urmă ridică probleme grave de mediu. Nivelurile TSS, COD și BOD5 au depășit standardele UE și EPA privind efluenții. Concentrațiile de COD și BOD5 estimate au fost mai mari decât pentru alte fabrici de bere raportate și dincolo de criteriile de referință ale Asociației Berarii, SUA. Apa uzată a fabricii de bere are un COD mediu de 83240 mg/L și BOD5 de 11066 mg/L și sunt contaminate la curățarea sticlelor și amestecarea efluenților. Prin urmare, pentru a reutiliza volumele mari de ape uzate și pentru a reduce nivelurile excesive de COD, efluenții din ABCSC necesită o atenție deosebită înainte de deversarea lor în canalizarea publică.</p></cfAbstr> <cfResPubl_Class> <cfClassId>eda2d9e9-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>759af938-34ae-11e1-b86c-0800200c9a66</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> </cfResPubl_Class> <cfResPubl_Class> <cfClassId>e601872f-4b7e-4d88-929f-7df027b226c9</cfClassId> <cfClassSchemeId>40e90e2f-446d-460a-98e5-5dce57550c48</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> </cfResPubl_Class> <cfPers_ResPubl> <cfPersId>ibn-person-91898</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-103196</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-103197</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-103198</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-103199</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> </cfPers_ResPubl> <cfFedId> <cfFedIdId>ibn-doi-165790</cfFedIdId> <cfFedId>10.52326/jes.utm.2022.29(3).12</cfFedId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> <cfFedId_Class> <cfClassId>31d222b4-11e0-434b-b5ae-088119c51189</cfClassId> <cfClassSchemeId>bccb3266-689d-4740-a039-c96594b4d916</cfClassSchemeId> </cfFedId_Class> <cfFedId_Srv> <cfSrvId>5123451</cfSrvId> <cfClassId>eda2b2e2-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>5a270628-f593-4ff4-a44a-95660c76e182</cfClassSchemeId> </cfFedId_Srv> </cfFedId> </cfResPubl> <cfPers> <cfPersId>ibn-Pers-91898</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-91898-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> <cfFamilyNames>Aremanda</cfFamilyNames> <cfFirstNames>Ramesh Babu</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-103196</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-103196-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> <cfFamilyNames>Arsiema</cfFamilyNames> <cfFirstNames>Tekle</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-103197</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-103197-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> <cfFamilyNames>Heaven</cfFamilyNames> <cfFirstNames>Daniel</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-103198</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-103198-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> <cfFamilyNames>Filmon</cfFamilyNames> <cfFirstNames>Berhane</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-103199</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-103199-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2022-10-05T24:00:00</cfStartDate> <cfFamilyNames>Abiel</cfFamilyNames> <cfFirstNames>Mehari</cfFirstNames> </cfPersName_Pers> </cfPers> <cfSrv> <cfSrvId>5123451</cfSrvId> <cfName cfLangCode='en' cfTrans='o'>CrossRef DOI prefix service</cfName> <cfDescr cfLangCode='en' cfTrans='o'>The service of issuing DOI prefixes to publishers</cfDescr> <cfKeyw cfLangCode='en' cfTrans='o'>persistent identifier; Digital Object Identifier</cfKeyw> </cfSrv> </CERIF>
