Various wastewater treatment technologies are available today and biological processes predominantly used in these technologies. Increasing systems produces large amounts of sewage sludge with variable quantities qualities, which must be properly managed. Anaerobic aerobic digestion composting major strategies to treat this sludge. The main indicators stabilization volatile fatty acids (VFAs), ...

Sludge management has been regarded as an environmental challenge to deal with due high energy costs for wastewater treatment plants. From this perspective, of sludge should be defined and calculated in order obtain effective Energy consumption is the major constituent operational costs. Especially, dewatering processes have led electricity at industrial This paper aimed define role design para...

Abstract The huge amounts of sewage sludge produced by municipal wastewater treatment plants induce major environmental and economical issues, calling for advanced disposal methods. Traditional methods increase greenhouse gas emissions pollution. Moreover, biochar created from often cannot be used directly in soil applications due to elevated levels heavy metals other toxic compounds, which alt...
