Item Removal of nitrates in wastewaters(2016) Angar, Yassmina; Djelali, Nacer-Eddine; Kebbouche-Gana, SalimaItem Extractive purification of hydro-treated gas oil with N-methylpyrrolidone(Serbian Chemical Society, 2017) Bedda, Kahina; Hamada, Boudjema; Kuzichkin, Nikolay V.; Semikin, Kirill V.The purification of hydro-treated gas oil by liquid–liquid extraction with N-methylpyrrolidone as solvent was studied. The results showed that this method, under appropriate experimental conditions, reduced the sulphur content of the gas oil from 174 to 28 ppm, the nitrogen content was decreased from 58 to 15 ppm, the aromatics content was diminished from 27.1 to 13.8 % and the polycyclic aromatic hydrocarbons were totally extracted. The obtained refined gas oil could be used to produce clean diesel fuel, thus protecting the environmentItem Novel approach for the ammonium removal by simultaneous heterotrophic nitrification and denitrification using a novel bacterial species co-culture(Springer, 2016) Angar, Yassmina; Kebbouche-Gana, Salima; Djelali, Nacer-Eddine; Khemili-Talbi, SouadItem Comparison of biological nitrate reduction effectiveness of two strains isolated from activated sludge(Chemical Publishing, 2016) Angar, Yassmina; Kebbouche-Gana, Salima; Djelali, Nacer-EddineItem Biological denitrification heterotrophe of water with fixed biomass using alfa stems as energy source(2010) Belouanas-Benbelkacem, O.; Benrachedi, K.This work presents the results optimization of the biological process denitrification with fixed biomass using a consumable support (Alfa Stem). In the first part, the influence of hydrolyc and volumic load to value the capacity of nitrate purification in a down flow submerged bio filter was analyzed. Then with an experimental design approach, we have analyzed the qualitative and quantitative aspects of the effects of some factors: concentration of nitrate (80-200 mg L-1) and velocity (0.3-1.0 m h-1) on different responses like the apparent rate of denitrification, as well as concentration of nitrite, nitrate and chemical demand on oxygen in the reactor outlet
