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...
