Characterization Qualitative Of Soel For A Valorization Best Of The Biomass Produced
(University of Eloued جامعة الوادي, 2015-01-01) M’sadak, Y.; Saad, I.
The main objective of this study was to qualitatively characterize biomass of Solanum elaeagnifolium Cav. (or SOEL) to highlight the essential alternatives its valorization. At first, we studied the potential of composting biomass of this plant. The physico-chemical characterization of biomass silverleaf nightshade has detected a wealth in organic carbon, which highlighted the potential value of this plant in the Co-composting with other biodegradable waste. In a second step, we assessed the possibility to develop this plant in the area of treatment in textile effluents by biosorption of dyes on fibers from the biomass of this plant, especially after the discovery of high levels of cellulose in its different organs.
Effect Of Heat Treatment On The Germination Of Seeds Soel
(University of Eloued جامعة الوادي, 2015-01-01) M’sadak, Y.; Saad, I.
The object of this work was to study the effect of thermal treatments (in the oven and in the compost) on the seed germination SOEL. The laboratory evaluation on the treatment in the oven berries at two temperatures (50°C and 60°C) for three exposure time ( one day, two days and three days) gave a germination rate zero for 60°C for an exposure time of one day. The spatio-temporal thermal monitoring of forestry compost windrow which was introduced to deal with berries SOEL showed a substantially homogeneous distribution of the temperature rising to 60°C and even longer swath stretching and used for a time period of 5 consecutive days. The germination rate was zero for all fruit seeds treated before the first reversal fact, regardless of the depth and location of the windrow considered that the berries were introduced. Thus, composting can be a solution to prevent the spread of SOEL by seed.
Monitoring And Thermal Analysis Of Co-composting Process In A Forest Nursery Modern (tunisia)
(University of Eloued جامعة الوادي, 2013-01-01) M’sadak, Y.; Saad, I.; Saidi, D.
The objective of this work was to study thermogenesis during the process of Co-composting to assess the possibilities of thermal destruction of the germination capacity of weeds seeds. A regular monitoring of temperature has been achieved, using a probe thermometer, at nine locations of heap crafted. The outlines of temperature profiles allowed the identification of the four phases of the process, from a temperature monitoring, which is taken twice a day. The mid-monthly monitoring of temperatureshowed no significant differences for the first three dates of monitoring, whatever the depth and whatever time study. The bi-monthly monitoring showed insignificant differences for the first three dates, whatever the depth of the heap and whatever the studied time. The last three dates showed insignificant differences for the time of recording, whereas for the depth, the results obtained were significant.
