Enhancing BOD5/COD ratio co-substrate tofu wastewater and cow dung during ozone pretreatment
Ozonation pretreatment was applied to enhancing BOD/COD ratio co-substrate tofu wastewater and cow dung. Ozonation pretreatment were conducted at pH of 5.2,8.0, and 10.0, with contact times of 20, 40, and 60 minutes. The results showed that the best condition for enhancing biodegrability is pH of 10...

| Summary: | Ozonation pretreatment was applied to enhancing BOD/COD ratio co-substrate tofu wastewater and cow dung. Ozonation pretreatment were conducted at pH of 5.2,8.0, and 10.0, with contact times of 20, 40, and 60 minutes. The results showed that the best condition for enhancing biodegrability is pH of 10 and contact time of 60 minutes with increasing BOD/COD ratio from 0.06 to 0.49, indicating an easy biodegradable substrate category. |
