The experimental study was carried out on an urban wastewater purification station located in the region of El Oued -Kounine- in south-eastern Algeria. During 6 months, samples were taken every month to study the Physico-chemical parameters of this station. Monthly monitoring of SS, COD, BOD5 was made from September 2017 to February 2018 and the results obtained show that the average elimination rates were 77.76, 74.10 and 80% respectively for BOD5, DCO and SS. The average of the ratio COD/BOD5 during the 6 months of follow-up is equal to 2.9.
TRANSPORT PROPERTIES OF BINARY LIQUID MIXTURES IN MEK WITH BROMOBENZENE
(جامعة الوادي - university of el oued, 2014) Miloudi, Abdelmonem; Remini, Bouallem
Viscosities and densities for MEK with Bromobenzene have been measured as a function of mole fraction at atmospheric pressure and at temperatures of 303.15 K, 308.15 K, and 313.15 K. The calculated deviations in viscosities and excess volumes were reported. McAllister’s three-bodyinteraction model, Krishnan and Laddha model and the Jouyban Acree model were used to correlate the kinematic viscosity of the systems. The excess volume data was fitted by means of the Redlich- Kister equation. It was found that in all cases the experimental data obtained fitted with the values correlated by the corresponding model very well
Water Potentiality of Sustainable Management Challenges in the Oued Souf Region, south east Algeria
(جامعة الوادي - university of el oued, 2015) Miloudi, Abdelmonem; Remini, Bouallem
This work reports a study on the effect of ultrasound on the behavior of Candida rugosa lipase in the enantioselective transesterfication of some racemic secondary alcohols (1- phenylethanol, 2-pentanol, menthol) with different acyl donors (vinyl acetate, vinyl propionate, vinyl butyrate) in the presence of organic solvents. The experiments were conducted with two different approaches: ultrasonic irradiation without stirring and stirring after ultrasonic pre-irradiation of lipase. The same experiments were conducted under conventional stirring to evaluate the effect of the ultrasound. The influence of preirradiation time, organic solvents, acyl donors and temperature were investigated. With the two approaches, the ultrasound has advantage over the conventional stirring. The best results were, however, obtained when the reactions were conducted under ultrasound without stirring. In the resolution of the menthol by vinyl acetate in hexane, the conversion increased 3-fold and the enantioselectivity 5-fold.
