Microalgae-bacterial biomass outperforms PN-anammox biomass for oxygen saving i...

The dissolved oxygen (DO) concentration in water streams is one of the most important and critical quality parameters in aquaculture farms. The main objective of this study was to evaluate the potential of two Continuous Flow Granular Reactors, one based on Partial Nitrification-Anammox biomass (Aquammox CFGR) and the other on Microalgae-Bacteria biomass (AquaMab CFGR), for improving dissolved oxygen availabili...

Microalgae attachment to aerobic granular sludge for the treatment of freshwate...

Nitrogen removal from freshwater aquaculture effluents: sequencing versus conti...

Microalgae-bacterial granular sludge for the treatment of low carbon and nutrie...

Granular sludge technology has plenty of advantages over conventional suspended sludge, mainly attributed to its extraordinary capacity for nutrient removal, efficient settling properties, and the feasibility of the operation. Over the last few decades, the application of microalgae-bacterial based systems for wastewater treatment has gained interest in the scientific community. The symbiotic relationship that ...

Sequencing versus continuous granular sludge reactor for the treatment of fresh...

Ammonium and nitrite levels in water are crucial for fish health preservation and growth maintenance in freshwater aquaculture farms, limiting water recirculation. The aim of the present work was the evaluation and comparison of two granular sludge reactors which were operated to treat freshwater aquaculture streams at laboratory-scale: an Aerobic Granular Sludge - Sequencing Batch Reactor (AGS-SBR) and a Conti...

Aerobic granular sludge, a feasible technology for the treatment and recirculat...

Aquaculture is one of the fastest growing food production sectors. However, land-based aquaculture faces water scarcity and space restrictions which hamper its development. Aquaculture recirculation systems (RAS) help tackle these problems, although in most systems the recycling of water increases nutrient and organic matter concentrations, which often translates to fish mortality. This work aimed to evaluate t...

Cultivable microalgae diversity from a freshwater aquaculture filtering system ...

Aims: Microalgae are ubiquitous in aquatic environments, including aquaculture farms, but few studies have delved into their phytoplankton diversity and bioremediation potential. In this study, the cultivable phytoplankton of a rainbow trout freshwater aquaculture farm was isolated, phylogenetically analysed and used to assemble a consortium to polish an aquaculture derived effluent, with low concentrations of ...

Control of zootechnology leads to improved cuttlefish (Sepia officinalis, L.) r...

Cephalopods are gaining momentum as an alternate group for aquaculture species diversification, not only because they are a good food source (highly appreciated in some worldwide markets) but they also have the potential to quickly reach a market size. However, there are some bottlenecks impeding the transition of culture technology from the laboratory to industry. One is related to control over reproduction in...
