Active Sludge and Aerobic Digestor
Fats and oils are the most common contaminants in wastewater and are usually discarded 17 through physical processes. This paper studies its elimination through an environmentally friendly 18 biological treatment, yielding good results on both laboratory scale and in the field. In this study a 19 comparative evaluation of the biodegradation of fats and oils in two scenarios were developed in 20...
متن کاملBiodegradation of Lignocelluloses in Sewage Sludge Composting and Vermicomposting
Aims of the Study: The aim of this study was to determine the amount of lignin degradation and biodegradation of organic matter and change of biomass under compost and vermicomposting of sewage sludge. Materials & Methods: Sawdust was added to sewage sludge at 1:3 weight bases to Carbon to Nitrogen ratio of 25:1 for composting or vermicomposting. Lignin and volatile solids were deter...
متن کاملStability and Kinetic Analysis during Vermicomposting of Sewage Sludge
The present study is aimed at alteration of sewage sludge into stable compost product using vermicomposting of sewage sludge mixed with cattle manure and saw dust in five different proportions based on C/N ratios (C/N 15 (R1), 20 (R2), 25 (R3) and 30 (R4); and control (R5)) by employing an epigeic earthworm Eisenia fetida. Higher reductions in C/N ratio, CO2 evolution and OUR were observed in R...
متن کاملFeasibility of nutrient recovery from industrial sludge by vermicomposting technology.
Transformation of industrial sludges into vermicompost is of double interest: on the one hand, a waste is converted into value added product, and, on the other, it controls a pollutant that is a consequence of increasing industrialization. This paper reports the feasibility of utilization of vermicomposting technology for nutrient recovery from industrial sludge in laboratory scale experiment e...
متن کاملManagement of Kitchen Waste Material through Vermicomposting
India produces around 3000 million tones of organic waste annually. This huge volume of waste(s) comes from agriculture, urban and industrial sources and also from domestic activities. Utilization of this waste material for productivity process is important for both economical and environmental reasons. In the present study an effort has been made to asses the efficacy of E. foetida (red tiger ...
