Última Capacité des moules dans la réduction des teneurs en nutriments et la charge bactérienne dans les effluents piscicoles OceanDocs Romdhane, M.S.; Chebil Ajjabi, L.; El Abed, O.. L’effluent des élevages de poissons renferme des concentrations plus élevées en nutriments dissous et en particules en suspension que celles présentes dans l’eau entrante. Cet état entraine par conséquent, des problèmes d’ordre environnementaux affectant les eaux côtières dues à l’eutrophisation et l’augmentation de la turbidité. Afin d’améliorer la qualité de l’effluent avant son déversement dans le milieu naturel, l’utilisation des bivalves comme filtre biologique est une alternative adéquate. Cette étude analyse la capacité de la moule Mytilus galloprovincialis de réduire les teneurs en sels nutritifs et la charge bactérienne dans les effluents de loups Dicentrarchus labrax en élevage. L’effluent issu des bassins de grossissement est pompé directement...

Elle contribue de manière non négligeable aux objectifs de croissance de l'économie nationale, notamment à la réduction du déficit de la balance des paiements, du chômage ainsi qu'a la satisfaction des besoins alimentaires des populations.

Due to the necessity to protect the surrounding environment and very specially the inner and coastal waters, were studied different wastewaters systems for their application in facilities without treatment plants. In the very special case of the fishing industry, where only 14 establishments (from 42 active up to the moment) have treatment system, one requires of the study of different alternatives that contribute with the diminishing of the polluting load until permissible values. By such reasons, in addition to the study that was doing to explore and propose a treatment system by high rate pond with the microalgae Chlorella spp., empirical and kinetic equations were calculated using biochemical oxygen demand values, with the objective to facilitate the...

OceanDocs Romdhane, M.S.; Chebil-Ajjabi, L.; El Abed, A.. Afin de mettre en évidence l’aptitude de deux espèces d’algues rouges Gracilaria verrucosa et Gracilaria bursa-pastoris pour le traitement des effluents et leur utilisation potentielle, une série d’expériences a été réalisée ayant pour but d’expliquer le comportement de ces deux espèces d’algues vis à vis de la source d’azote. Dans une première expérience, on a pu déterminer la forme d’azote (N-NH4 , N-NO3) preférentielle pour chacune des deux espèces d’algues cultivées séparément. Elles ont une nette préférence pour N-NH4 et cela pour une même concentration initiale. Cependant, G. verrucosa est un candidat plus performant que G. bursa-pastoris pour l’assimilation des deux formes d’azote. Etant identifié comme source préférentielle, N-NH4 a été utilisé...

Ano: 2005 URL: http://hdl.handle.net/1834/3776 Ozone treatment of textile wastewater relevant to toxic effect elimination in marine environment OceanDocs Guendy, H.R.. Ozone is a powerful oxidizing agent. The reaction of ozone with organic compounds in aqueous media has achieved a variety of treatment goals. The advantage of ozonation over the other oxidants is that the degradable products of ozonation are generally non-toxic, its final products are CO2 and H2O, and also the residual O3 in the system changes in few minutes to O2 .Convential treatment of textile wastewater includes various combinations of biological (activated sludge), physical and chemical processes. The dyestuffs existed in these wastewater are highly structured organic molecules which are hardly break down biologically. Decolorization of two types of dyes, Direct Pink 3B and Reactive Violet SH- 2R, by ozonation in aqueous medium was studied in presence...

The rate of reduction of Cr6+ to Cr3+ reaction in K2Cr2O7 has been studied and it is found to be first order. The rate of reaction at 0.05 mole of K2Cr2O7 have been measured in absence of quaternary ammonium salts as CTAB (Cetyl trimethyl ammonium bromide) and CPYB (Cetyl trimethyl pyridinium bromide). The rates of reaction are also measured in presence of CTAB and CPYB at four different temperatures (25, 30, 35 and 40oC). Effects of rotations are also studied. The rate of reaction was decreased by addition of salts. Thermodynamic parameters ∆G*, ∆H* and ∆S* are given.
