The subject of this report is efficient phosphorus recovery from effluents by precipitation in basic solution of an insoluble calcium phosphate in either a fluidised bed of hydroxyapatite (HAP) seeds or in a stirred reactor. In the case of a synthetic effluent containing only phosphorus (50mg/L), the final concentration after treatment is reduced to less than 1mg/L when the temperature (35°C) and the pH (7. 5) are suitably selected. Precipitation, crystalline growth and coating phenomena were studied. Under the optimal conditions, the treatment using the fluidised bed process allows the precipitate to be retained entirely within the bed. Magnesium assists the coating in the fluidised bed process but inhibits crystalline growth. However at high pH (above 9) the phosphorus is recovered effectively. In all cases the recovered phosphorus can be directly reused by phosphate manufacturers

Fischer-Tropsch process allows to obtain high quality lubricant bases and clean fuels from natural gas. In this goal, the n-paraffins produced have to be upgraded through a hydroconversion step aiming the isomerization of chains. In order to better understand the mechanisms involved, different bifunctional catalysts have been studied for the hydroconversion of n-hexadecane on a lab-scale trickle bed reactor. These catalysts are : a benchmark Pt/EMT, two commercial catalysts (Pt-Pd/SiO2-Al2O3), tungstated zirconias, as well as a new class of mordénite-based micro/mesoporous composite catalyst. A specific study highlighted the effects of mechanical treatments on activity and selectivity of tungstated zirconias. Relations between physico-chemical characterizations of the catalysts and their activities and selectivities for the hydroconversion of n-hexadecane were established

The major subject of this research is the conceptual study of a transmembrane distillation process for the recovery of industrial effluents. The scientific issues studied in this work are covered by advanced separation processes: Materials: dense or porous polymers, experimental quantification at laboratory scale of the mass transfer mechanism, modelling of mass and heat coupled transfers, process simulation and optimization. In this thesis, the technological issues are addressed by a process simulation approach. A numerical unit operation brick for membrane technology simuation is proposed. It considers the physical and chemical phenomena at three levels: material, module (geometry, flow patterns) and process (operating conditions). The generic mathematical model presented in this work is adapted to three systems of industrial interest: water desalination (non-volatile component), boron-containing effluent treatment (component less volatile than water) and ammonia recovery (component more volatile than water). The adaptation of the mathematical model is based on experimental data found in the literature and complemented by experiments performed on laboratory-scale equipment. These experiments target the comprehension of the two main phenomena necessary for the calculation of the process selectivity: the modelling of the liquid-vapour equilibrium and the evaluation of the transfer coefficients for each component at the material level. This dedicated code, modified with the experimental results, is then integrated into a process simulation software, allowing architecture optimization, process synthesis and optimization. Industrial issues are evaluated by comparing traditionally deployed technologies (thermal-based technologies) with membrane technologies based on the evaluation of energy and production performances. Finally, the results allow the identification of the transmembrane distillation potential for the selective separation of components as alternative processes to existing technologies
Escudero, Oñate Carlos. "Valorisation of industrial wastes for the removal of metals and arsenic from aqueous effluents." Doctoral thesis, Universitat de Girona, 2009. http://hdl.handle.net/10803/7802.
The present thesis focuses on the removal of heavy metal cations and arsenic from polluted aqueous effluents by adsorption onto low cost sorbents. These materials are, in all the cases, by-products of agroalimentary or metallurgical industries.The document is formed by different chapters structured in three sections. These sections concern: (i) Hexavalent and trivalent chromium removal, (ii) heavy metal cations removal in presence of complexing agents and from multimetal mixtures and (iii) arsenic removal by sorption onto a by-product of an electroplating industry.The results obtained point out that several industrial wastes can be successfully used as sorbents to remove heavy metals from aqueous polluted effluents. The proposed technology represents a low cost and environmental-friendly alternative to the current treatments, more expensive and many times, dependent of oil derivatives.

The purpose of this study to valorize solid wastes from the Solvay process for the production of sodium carbonate as reagents for the treatment of H2S in air at concentrations typically found in wastewater treatment plants (tens to hundreds of ppmv of H2S). Firstly, the reactivity of two residues was evaluated in a gas-liquid-solid reactor at laboratory scale (250 ml). This reactor operates semi-continuously (continuous passage of gas through a fixed volume of slurry). The influence of operating parameters including the solid content of the suspension, the concentration of H2S, the stirring speed and the volume of suspension was discussed. The kinetics, physicochemical processes as well as mechanism involved have been identified despite the complex reaction medium. Secondly, the H2S treatment was investigated at pilot scale using a bubble column with trays (170 L) which also operates in semi-continuous mode. The results of the parametric study obtained at laboratory scale were checked at pilot scale. Finally, the column was evaluated with a real gaseous effluent from a wastewater plant in Graulhet (Tarn, France) which contains up to 200 ppmv of H2S. In the presence of other gases as methane (0.4% vol.) and carbon dioxide (2.5% vol.), the system has proven to be effective for the selective elimination of H2S. A near total abatement (100%) was maintained for at least two weeks with only one batch of suspension. Stable and non-volatile sulfur compounds (sulfates, sulfites, thiosulfates) were formed as products of the process. This study demonstrates the competitiveness of the process in terms of cost-effectiveness for the treatment of H2S in ambient conditions. The results obtained also demonstrate the possibility of scaling-up the method to an industrial scale

Lignin is a polymeric constituent of vascular plants’ pectocellulosic walls. It is a by-product, poorly upgraded from pulp and paper, and biorefinery industries. To evaluate their potential in agrocomposites field, commercial lignins (sodium lignosulfonates and Kraft lignin) were processed along with corn cob, an agro-industrial residue used hereby as a natural fibre. Firstly, a compression-moulding process allowed the combination of hydrated sodium lignosulfonates and corn cob particles. The impact of three factors (particle size, fibre content, and compacting pressure) on compressive mechanical properties was measured. Although sodium lignosulfonates cross-linking by commercial laccases was highlighted in solution, addition of such enzymes to agrocomposites formulations did not improve their flexural strength (maximum value of 5.3 MPa). The acoustic insulation properties of agrocomposites (sound transmission loss of 60 dB) and their thermal conductivity of 0.143 W.m - 1.K -1 may suggest applications in the building sector. Secondly, nine formulations of bio-based materials were developed by twin-screw extrusion, and then injection moulding, combining a bio-based thermoplastic polymer matrix (polylactic acid and/or poly(butylene succinate)) with technical lignins (2.5 to 20% (m/m) Kraft lignin or sodium lignosulfonates), and corn cob particles (5 to 19% (m/m)). The addition of Kraft lignin led to increased hardness of the materials up to 50%, and more hydrophobicity compared to polylactic acid. Nevertheless, their mechanical strengths decreased (by a maximum of 40%), and materials exhibited a more brittle fracture profile. In the presence of corn cob, transfer of forces from matrix to fibres was not ideal since de-bonding was detected at the interfaces under irreversible flexural stress. However, these bio-based materials exhibited mechanical, and thermal properties that made them suitable for synthetic plastics substitution while adding value to by-products of agricultural, and forest industries
