2020/11/1/ · 1. Introduction. Waste activated sludge (WAS) is the solid waste produced during the biological treatment of wastewater (Wei et al., 2020), especially from municipal wastewater treatment plants (WWTPs).In China, the continuous construction of sewage drainage systems and wastewater treatment facilities has resulted in an increase in the

Composting with five levels of green waste and sewage sludge was compared to examine how feeding ratios affected composting performance with special focus on humification, and the underlying mechanisms. The results showed that the raw material ratio persistently affected compost nutrients and stabil

2023/4/1/ · The co-composting of the sewage sludge and rice husk reduced TOC losses. Villaseñor et al., (2011) reported that in the composting of domestic sewage sludge with different natural materials in a rotary drum reactor, the carbon loss in the reactor containing 25 % mordenite was 58 % (Villaseñor et al., 2011).
