2013/7/23/ · The present study evaluates working performance of rotary drum reactor (RDR) and aerated In tank (AIV) for composting of garden waste. 100 kg garden waste was mixed with 10 kg cow-dung slurry
2007/11/1/ · Abstract. We investigated the simultaneous degradation of diesel oil in soil and the organic matter in food waste by composting in 8 l reactors. Using a 0.5 l/min air flow rate, and 0.5-1% diesel
2003/10/1/ · The data obtained from GC analyses can also be converted to bulk TPH concentrations. Fig. 4 shows percentage degradation of TPH in the slurry reactors under various electron acceptor conditions studied over the course of the experiment. The TPH was removed 80.5%, 55%, 50%, 40%, and 27% under the mixed electron acceptor,
2019/2/2/ · Reactor operation details are provided in the Supplementary Information section . Briefly, the amount of contaminated soil processed with this pilot reactor ranged from 28 lb/h for a residence time of 15 min down to 7 lb/h when the kiln rotation speed was adjusted to maintain a residence time of 60 min.
aggregate reactors for soil–atmosphere GHG exchange are determined by both an individual reactor's reactivity and dynamics in aggregate size distributions. Emerging evidence supports the contention that aggregate reactors significantly influence soil–atmosphere GHG exchange and may have global implications for carbon and
2016/12/1/ · Composting materials were considered as porous substrates that had a temperature of t c and a porosity of γ, was piled to a height of H, had a diameter of d 1, and a surface area of A 1.Temperature of structural layer on the inside was t w 1.Note that both conductive heat transfer between compost and structural layer and convective heat
soil by composting, findingthat theremovalpercentages of anthracene for composting materials with old compost and without old compost were 55.3% and 50.5%, respectively. Pig manure which is able
Acid mine drainage (AMD) is a serious environmental problem resulting from extensive sulphide mining activities. The old copper mine of S. Domingos in Southeast Portugal is an example of such a situation. The abandoned open-pit from the mining operations resulted in the creation of a large pit lake with acidic water (pH∼2) and high contents of sulphate and
2003/12/1/ · The bioremediation of 2,4,6-trinitrotoluene (TNT) contaminated soil was performed on a laboratory scale. To compare bioremediation , a soil slurry reactor and a soil column reactor were operated and the effects of supplemental sources were investigated. Optimal conditions for the two bioremediation systems for the removal of …
2022/2/1/ · The soil was sieved and homogenized using cone and quartering . It was estimated that 1.0–1.5 kg of dry soil were used for the treatment. The electrokinetic reactor and soil material used had the same characteristics as previous research published elsewhere, as shown in Fig. 1 (Ramadan et al., 2018a).
