Research Aim: This research finds the impact of enhanced anaerobic baffle cum filter reactor on household wastewater treatment in China. It will show how the introduction of an anaerobic baffle cum filter affected the treated household wastewater quality. Moreover, it will analyze the current practices in China. It will compare them with other major countries such as the US, UK, Japan, etc., to differentiate between different methods with the same technology. Lastly, it will propose changes in the current practices to improve the efficacy of an enhanced anaerobic baffle cum filter reactor.
