tailieunhanh - A study to use activated sludge anaerobic combining aerobic for treatment of high salt seafood processing wastewater

This research aimed to study the effect of salt (NaCl) concentration on the treatment efficiency of seafood processing wastewater by the use of a laboratory-scale bioreactor, which is operated in anaerobic combining aerobic system with concentration salt different from 0- 5%. | A study to use activated sludge anaerobic combining aerobic for treatment of high salt seafood processing wastewater Current Chemistry Letters 9 2020 79 88 Contents lists available at GrowingScience Current Chemistry Letters homepage A study to use activated sludge anaerobic combining aerobic for treatment of high salt seafood processing wastewater Thi Thu Hoai Phama and Thi Mai Huong Nguyenb a Department of Science research University of Economic and Technical Industries Vietnam b Department of Food Technology University of Economic and Technical Industries Vietnam CHRONICLE ABSTRACT Article history Seafood processing operations generate a high strength wastewater which contain organic Received August 2 2019 pollutants in soluble colloidal particulate form and salt content up to 30g NaCl L. This Received in revised form research aimed to study the effect of salt NaCl concentration on the treatment efficiency of August 18 2019 seafood processing wastewater by the use of a laboratory-scale bioreactor which is operated Accepted August 19 2019 in anaerobic combining aerobic system with concentration salt different from 0- 5 . The Available online August 19 2019 results showed that the wastewater from seafood processing with the chemical input parameters of pH 7 - COD 2000 mg L total nitrate nitrogen 150 mg L NH4 Keywords 90 mg L total phosphorus 50 mg L salt content 3 was treated with anaerobic activated Seafood processing wastewater Salt concentration sludge content of 8000mg l 16HRT and combining an aerobic activated sludge content of Activated sludge 6000mg l 6HRT DO 2-4mgO2 l with the acclimatization of 7 bacteria Bacillus velezensis Anaerobic at high salinity The parameters output wastewater was treated according to standards QCVN Aerobic 11-MT 2015 BTNMT column B . 2020 Growing Science Ltd.
