This study was focused on the characterization of physicochemical parameters of drinking water, which are mainly involved during water treatment or analysis processes. we were interested in the application of the experimental design methodology, according to the method of Yates on the parameters that characterize the quality of drinking water in Me...
Article
The damage at the interface zones between the fiber and the matrix of a composite structure is studied. It is assumed that the composite is submitted to external forces that can damage the fiber–matrix interface zones. In this work, we use the boundary integral equation method to investigate the damage at the fiber–matrix interface. This method i...

This article is devoted to the results obtained during the physicochemical treatment of colored indus-trial tannery discharges of the city of Moahammedia by coagulation flocculation. The volume of settled sludge is measured and the supernatant is recovered for the determination of the color of the treated water, this one is measured on samples prev...
Article
Full-text available
This article is devoted to the experimental procedure followed for the treatment of industrial waste colored by coagulation flocculation. The amount of water used and therefore the volume of the effluent and its pollution rate vary considerably depending on the production step. The variations of the COD, of the effluents of different stages of the...

This article is devoted to the experimental procedure followed for the treatment of industrial discharges of tannery by coagulation flocculation. These are industrial discharges from the tannery of the city of Mohammedia. A screening study will be presented for the analysis of the volume of sludge formed, in order to identify the most influential f...

Dans ce travail de recherche, nous nous sommes intéressés dans un premier temps à la caractérisation des effluents de l’industrie de tannerie. Ainsi de nombreux paramètres ont été déterminés. Présentant une grande variabilité le long des différentes étapes du processus, ils montrent une charge polluante très élevée aussi bien en matière organique q...
Article
The physicochemical process of coagulation–flocculation was highly effective and economically suitable for leachate treatment. The leachate is characterized by a high chemical oxygen demand (COD), between 2,153 and 2,707 mg/L. The organic matter was not easily biodegradable (BOD5/COD: 0.2–0.135). Metal concentrations ranged between 0.1 and 4.2 mg/L...

This work is focused on the effects of certain factors of the efficiency of the waste treatment industry tannery, by the method of experiments. The tannery effluents on the study were treated by coagulation-flocculation method. Factors such as the pH, the nature of the coagulant, the coagulant concentration, the concentration of the flocculant, the...

Abstract— In this work we examined the application of coagulation–flocculation for the treatment of stabilized leachates. Jar-test experiments were employed in order to determine the optimum concentration conditions for the removal of organic matter. Coagulant–flocculant combination, effective dosage Ferric chloride, Aluminum sulphate and Alginate...

Full-text available
In this work, we worked on the removal of pollution discharges stabilized leachate produced by the landfill of the city of Mohammedia using the process of the biodegradation of organic pollutants in air continuously or discontinuously. In order to predict the efficiency of a biological treatment for this type of effluent while minimizing the cost o...

This study has identify useful reduced mechanisms that can be used in computational fluid dynamics (CFD) simulation of the flow field, combustion and emissions of gas turbine engine combustors. Reduced mechanisms lessen computa-tional cost and possess the ability to accurately predict the overall flame structure, including gas temperature and spe-c...

The current study has identified a useful reduced mechanism that can be used to simulate the combustion of natural gas in computational fluid dynamic (CFD) code. This reduced mechanism can lower the computational cost and process of accurately predicting the overall flame structure, including gas temperature and radical intermediate species such CH...

A lagrangian concept based on the projected area entrainment initially formulated by Winiarski and Frick, and later on developed by Cheung and Lee, is used to predict the effects of some physical properties of the atmosphere which does not appear directly in most empirical formula used to calculate the height of some industrial plume. Special consi...
Article
Full-text available
The simulation of the combustion for the prediction of the processes and the physical variables, is rather complex when detailed mechanisms are used. The reduced mechanisms of reactions, involving a small number of steps and chemical species, are thus of paramount importance. The CSP method was applied for the reduction of the detailed mechanism GR...
Article
Full-text available
Combustion is a complex field, because it simultaneously involves several disciplines such as the heat transfer, the chemistry, the turbulence, the transport of mass etc. In this work we tried to model an experiment having a combustion chamber with a geometry close to that of spark ignition engine. This modeling based on the approach of calculated...

Full-text available
The simulation of the combustion processes is rather complex when detailed mechanisms are used. The reduced mechanisms of reaction with a restricted number of reactions are thus of significant importance. These reduced mechanisms are composed of some steps, which imply a limited number of chemical species. In this paper the method of CSP [1, 2] was...

Full-text available
A Lagrangian plume model, based on the so-called projected area entrainment (PAE) hypothesis suggests that the interaction between a plume and wind causes enhanced entrainment of air and horizontal momentum, plume bending, and a decrease in plume rise height at constant flow emission rate. For plume with larger radius (or small wind speed), the pro...

Combustion is a very complex field, since it simultaneously involves several disciplines such as heat transfer, chemistry, turbulence, mass transport etc. In this paper we tried to model a combustion chamber with a geometry close to that of the spark ignition engine. The initial and boundary conditions are well-known. The modeling is based on the a...

The modelisation of combustion is central problem in most practical combustion system. In this work, turbulent combustion is discussed with a lagrangian model, which is useful for the study of turbulent combustion problem. A coupling between this lagrangian model and the presumed probability density function (pdf) method is used with complex chemis...

The simulation of the combustion for the prediction of the processes and the physical variables, is rather complex when detailed mechanisms are used. The reduced mechanisms of reaction with a restricted number of steps are thus of paramount importance. These reduced mechanisms are composed of some steps, which imply only one number limited of chemi...
