Feasibility 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 کاملVermicomposting of Vegetable Market Waste Using Perionyx Ceylanensis
Due to human activities huge amount of organic wastes are simply dumped in the environment creating disposal and pollution problems. Suitable and sustainable utilization of these wastes is vermicomposting which converts wastes in to wealth. In the present study, 1:1 proportion (wt./wt.) of vegetable market waste (VMW) and press mud (sugar industry waste) mixture have been used for vermicomposti...
متن کاملGrowth and reproduction of Perionyx excavatus in different organic wastes
Earthworms have been successfully used in the vermistabilization of urban, industrial and agricultural wastes in order to produce organic fertilizers and obtain protein for animal feed. Although many species could be used for these ends, given their nutritional requirements and reproductive biology, only Perionyx excavatus and Lampito mauritii are widely used. The most effective use of earthwor...
متن کاملFeasibility of vermicomposting in biostabilization of sludge from a distillery industry.
The feasibility of vermicomposting technology to stabilize the distillery industry sludge mixed with a bulking agent (cow dung) in different proportions viz. 20% (T1), 40% (T2), 60% (T3) and 80% (T4), was tested using composting earthworm Perionyx excavatus for 90 days. The vermitreated sludge was evaluated for different physico-chemical parameters and all vermibeds expressed a significant decr...
متن کاملIsolation and Characterization of Polyacrylamide-Degrading Bacteria from Dewatered Sludge
Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces hazardous monomers. In the present study, the bacterial strain HI47 was isolated from dewatered sludge. This strain could metabolize PAM as its sole nutrient source and was subsequently identified as P...
