Abstract:

Le développement rapide de l'aquaculture dans le monde rend indispensable la maîtrise de ses rejets. Par rapport aux systèmes traditionnels, les systèmes recyclés permettent de réduire les besoins en eau et le volume des rejets. Toutefois, certains nutriments dissous (nitrates, phosphates) s'y concentrent. Le lagunage à haut rendement algal (LHRA) est une des voies possibles pour éliminer ces nutriments. Au cours de ce travail, trois circuits d'élevage: un recyclé, un recyclé avec LHRA et un ouvert témoin ont été étudiés pendant un an pour évaluer l'effet (1) de la réutilisation de l'effluent

Abstract:

The development of techniques for the removal and recovery of metals from industrial effluent taking account of the consequences of the definition of waste in the Basel Convention on transfrontier shipment of waste is reported. The use of fluidised bed cell electrolysis in the recovery of metals from dilute solutions is investigated, and the conditions for recovery optimised. For the first time the application of a novel activated carbon cloth concentrator cell to recover metals from effluent solutions is reported and the conditions for its use optimised. Comparative studies using conventional

Abstract:

When performed at an industrial scale, kraft pulp bleaching commonly utilizes recycled chlorination effluent for brown stock dilution. Much of the information regarding this practice pertains to pulp quality. Some of the previous research done in this field failed to separate its effect from the effect of countercurrent effluent recycle for pulp washing. In addition, there are some shortcomings of the batch techniques that have been used to simulate effluent recycle in the laboratory. Thus little is known about the effect of this practice on effluent quality. Accordingly, the objective of thi

Due to issues with increased phosphorus emissions connected to increased concentration ofeffluent total suspended solids (TSS), Roslagsvatten would like to optimize the operation of their dissolvedair flotation (DAF) process and the author was tasked to conduct a study about the subject.

Abstract:

Thesis (MEng (Civil Engineering))--Cape Peninsula University of Technology, 2019<br>The textile industry is considered one of the most polluting sectors in terms of the large volume and toxic composition of the effluent that is generated. For example, the effluent contains dyes, which represent an environmental hazard when discharged without proper treatment. This study aimed to assess the use of recycled alum sludge (RAS) as an alternative treatment for the reduction of colour from dye based synthetic textile industry wastewater. To determine treatment efficiency, the colour, chemical oxygen

Depuis la révolution verte au milieu du 20ième siècle, le monde agricole est dépendant des engrais phosphorés à bas coûts, fabriqués à partir d'une ressource fossile et nécessaires à l'amélioration des rendements des cultures à même de répondre aux besoins en nourriture d'une population en forte croissance.

Taiwan is a country abundant in precipitation that amounts to an annual rainfall of ninety (90) billion cubic meters, yet constantly experiencing water shortage due to the high population. The rainy season is from May to October with the rest of the year relatively dry. Due to longitudinal shape of Taiwan and the steepness of mountains, rivers are short in general and water flows rather rapidly. The steep terrain makes it difficult to

Moreover, comparing to the current price of drinking water, the price of recycling water is still in much expensive level. Due to stable quality and quantity characteristics of sewage water, waste water recycle and reuse will be the future potential for development of local water supply sources, which also illustrates the future potential to
