Aproveitamento dos rejeitos da dessalinizacao.

LUIZ, D. B.; JOSÉ, H. J.; MOREIRA, R. F. P. M..

There are many studies and reviews on advanced processes to treat secondary wastewater from industries which also address the challenges and limitations to water reuse and the hygienic concerns especially in food industries. However, the challenges associated with treating a secondary wastewater to provide drinking water quality become clear when real wastewater is treated in batch and in pilot scale. The limitations are several, particularly in food industries. Hence, this review aims to present an overview and a discussion regarding the challenges and proposals related to the advanced treatment of food industry wastewater to provide drinking water quality, elucidating some experimental and theoretical questions surrounding such processes. Valuable...

Por sua comprovada eficiencia quanto a relacao custo quantidade de agua dessalinizada, a osmose inversa (RO) se destaca de outros processos de dessalinizacao e ja vem sendo utilizada em algumas comunidades no Nordeste do Brasil. Porem, o seu crescente desenvolvimento e utilizacao podera trazer impactos ambientais devido aos seus subprodutos ou rejeitos, isto e, aguas com elevados teores de sais que estao sendo despejados ao solo. Com o objetivo de adequar a tecnica da osmose inversas as aguas salinas oriundas dos aquiferos do cristalino, e de avaliar tecnicas de manejo eficiente dos rejeitos a fim de evitar problemas ambientais, o projeto pretende dessalinizar aguas por osmose inversa e estudar alternativas para uso e condicionamento adequado dos rejeitos....

Capacité des moules dans la réduction des teneurs en nutriments et la charge bactérienne dans les effluents piscicoles

Chebil Ajjabi, L.; Romdhane, M.S.; El Abed, A..

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...

Deammonification reaction in digested swine effluents.

La pêche est une composante essentielle du développement économique et social intégré. 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.

Abstract: Bisphenol A and ethinylestradiol, both considered as endocrine disruptors, have been found in surface water and effluents from municipal wastewater supply and can cause adverse health effects on wildlife species and in human beings at extremely low level. In order to remove these compounds from wastewater, constructed wetlands has been used since it proved to be more efficient, and has less cost than conventional treatments. One of the mechanisms of removal of endocrine disruptors by constructed wetlands is the uptake by macrophytes, so it is necessary to analyze these compounds in the plants of the system. Thus, the objective of this study was to develop and validate two methods by high performance liquid chromatography with fluorescence...

Determinaciones de parámetros de diseño para lagunas de alta velocidad con residuales pesqueros

Romero López, T.; Rodriguez Pérez, C..

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...

Effect of glutaraldehyde biocide on laboratory-scale rotating biological contactors and biocide efficacy

Electron. J. Biotechnol.

Laopaiboon,Lakkana; Phukoetphim,Niphaphat; Laopaiboon,Pattana.

The effect of glutaraldehyde, a commercial biocide widely used in paper and pulp industry, on the performance of laboratory-scale rotating biological contactors (RBCs) as well as biocide efficacy was studied. Biofilms were established on the RBCs and then exposed to 0 - 180 ppm glutaraldehyde at a dilution rate of 1.60 h-1. The results showed that the biofilms became acclimated to glutaraldehyde and eventually could degrade it. Acclimation to the biocide took longer at the higher biocide concentrations. The degree of biocide degradation and chemical oxygen demand (COD) removal depended on acclimation period, the presence of other organic matters and the amount of mineral salts available. Glutaraldehyde at up to 80 ppm had no effect on treatment efficiency...

Evaluatin of metabisulfite and a commercial stee wool for removing chromium (VI) from wastewater.

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...

From a pollutant byproduct to a feed ingredient.

GROMBONI, C. F.; DONATI, G. L; MATOS, W. O.; NEVES, E. F. A.; NOGUEIRA, A. R. de A.; NOBREGA, J. A..

Efficiency of metabisulfite and a commercial steel wool as reducing agents in the removal of Cr(VI) from wastewaters was evaluated. Chromium( VI) was converted to Cr(III), precipitated with NaOH, and removed by filtration. A reduction of more than 1.0 x 10(5) and 4.0 x 10(5) fold in total Cr and the Cr(VI) concentrations, respectively, was observed by employing steel wool masses as low as 0.4420 g to 30-mL solutions of wastewater. Chromium(III) hydroxide obtained after the treatment was recycled and used as marker in cattle nutrition studies. The liquid residue obtained after the treatment was reused as precipitation agent replacing NaOH.
