Investigation of energy costs for sludge management: a case study from dairy industry

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 parameters on process terms total organic carbon (TOC) volume index (SVI) considering water-energy nexus. Dissolved Air Flotation (DAF) centrifuge decanter were used a dairy plant. Lime stabilization. cost figured out using new derived numerical method. study proposed developed methodology assessment management. revealed that would lower if plant was operated under conditions. If conditions, nearly 63% reduction handling could ensured. It recommended
