Temperature analysis of a novel MAIB reactor during the treatment of wastewater from recycled paper mill

Anaerobic digestion (AD) is an essential technology for wastewater management, resource recovery and biogas production, and it is considered as an efficient and reliable treatment method for many wastewaters. Operating parameters have been shown to directly affect the stability and treatment perform...
