“…Recirculation systems in aquaculture allow controlled aquatic environments with stable conditions in terms of physical-chemical quality of the water; and especially temperature with very little variation, if new influent water is controlled [7,8]. Thus, this research has concentrated on the generation of an economic, efficient and safe technology that allows the adequate control of influent flow and recirculation.…”

Graphical AbstractTropical fish hatching coupling (TFHC) Abstract.This research has focused on the generation of an economic, efficient and safe technology that allows adequate control of water consumption and uses recirculation to control factors associated with water quality. Aquaculture companies interested in providing a recirculating aquaculture system (RAS) for tropical fish farming can replicate this prototype to be successful in all areas of production. The design was based on the use of locally available components, equipment and recycled containers for mechanical and biological filters. Two recirculation systems were implemented: i) maintenance of aquatic organisms (MAO); ii) tropical fish hatching coupling (TFHC). In both cases, operating tests were performed with electric and solar heaters. The requirements for oxygenation, evacuation, separation of biosolids, biofiltration, CO2 degassing, fish metabolites, pathogens control, temperature maintenance and variables measurement were all adapted and solved. Results show that the RAS provides controlled conditions for temperature, dissolved oxygen and pH stability. Nitrogen was safely removed in quantities acceptable to tolerant levels. Environmental adaptation for artificial hormonal induction treatments create a significant temperature increase. Solar heating adaptations stabilized this process; oxygen remained saturated and at respectable levels. The biofilter systems kept all important water quality parameters in balance. The recirculation systems removed NO2 and NO3 organic load. The recirculation flow rate was regulated in the MAO at approximately 10 l/min, a replacement rate of 120% per hour; while in the TFHC a flow rate of 7 l/min per incubator was used, i.e. 14 L/min in the system, which implies a replacement of 280% in the incubators and 170% in the maintenance tanks.

“…Plant top-growth provides nutrient uptake, shade for protection against algal growth and water removal in the form of transpiration, while the large mass of self-generating root systems and accumulated material serve as living filters (Danaher et al, 2013;Castillo et al, 2016). The system provides roughing or preliminary treatment by plant species with large root systems capable of surviving and growing in a grossly polluted condition.…”

“…Large sludge accumulations, anaerobic conditions and trace metal precipitation and entrapment characterize this mechanism and a large portion of wastewater BOD and suspended solids would thereby be removed. In addition, nutrient conversion and recovery occurs due to high biomass production and wastewater polishing is attained during nutrient-limited plant production (Leonard and Leonard, 2006;Danaher et al, 2013;Castillo et al, 2016). …”

Water is an essential resource that is required to sustain life. Its availability has to be adequate, safe and easily accessible. Current trends in climate change and rise in human population has compromised water adequacy, availability and safety. Wastewater managers around the world have the responsibility to ensure that the effluent that is eventually released into the environment does not degrade the quality of the recipient water bodies. Attaining sustainability in wastewater management is top in the of Sustainable Development Goals' Agenda. All in all, the realization of a more sustainable wastewater management will require a highly holistic and balanced approach in evaluating a particular management strategy's overall sustainability. Promoting the use of safe, affordable and adequately available wastewater treatment techniques is a step towards wastewater management for sustainability. This review paper therefore discusses some of the currently known and emerging wastewater management techniques that are considered essential in attaining Environmental Management and Sustainable Development ISSN 2164-7682 2017 http://emsd.macrothink.org 41 sustainability in water resource management.

“…In these integrated systems, nutrients that are excreted by the fish or generated by microbial activity (Munguia-Fragozo et al, 2015;Zou et al, 2016a) are absorbed by hydroponically cultured plants, thus treating the water before it is recycled to the fish tank (Endut et al, 2009;Tyson et al, 2011;Nichols and Savidov, 2012;Medina et al, 2016;Nuwansi et al, 2016). AP has received considerable attention due to its capability to sustain water quality, minimise fresh water consumption, and provide a marketable vegetable crop (McMurtry et al, 1997a(McMurtry et al, , 1997bAdler et al, 2000a;Lennard and Leonard, 2005;Graber and Junge, 2009;Danaher et al, 2011Danaher et al, , 2013Pantanella et al, 2011Pantanella et al, , 2015Espinosa Moya et al, 2016;Shete et al, 2016). Nevertheless few microbial studies have been conducted to determine food safety status (Elumalai et al, 2017) suggesting that further research is needed to evaluate this aspect.…”

“…In the AP, the water quality required for fish production is maintained through biofilter and/or hydroponic section where: i) plants absorb dissolved fish wastes and products of microbial activity (McMurtry et al, 1993;Danaher et al, 2013;Silva et al, 2015;Goddek et al, 2016;Andriani et al, 2017); ii) several substances are removed through gas volatilisation (CO2, CH4, N2, N2O,NH3,etc. ) by the same processes as in conoestructed wetlands (Mander et al, 2014;Maucieri et al, 2017).…”

Hydroponic systems and water management in aquaponics: a review

et al. 2017

Aquaponics (AP), the integrated multi-trophic fish and plants production in quasi-closed recirculating system, is one of the newest sustainable food production systems. The hydroponic component of the AP directly influences water quality (in turn influencing fish growth and health), and water consumption (through evapotranspiration) of the entire system. In order to assess the role of the design and the management of the hydroponic component on the overall performance, and water consumption of the aquaponics, 122 papers published from 1979 to 2017 were reviewed. Although no unequivocal results were found, the nutrient film technique appears in several aspects less efficient than medium-based or floating raft hydroponics. The best system performance in terms of fish and plant growth, and the highest nutrient removal from water was achieved at water flow between 0.8 L min -1 and 8.0 L min -1 . Data on water consumption of aquaponics are scarce, and no correlation between the ratio of hydroponic unit surface/fish tank volume and the system water loss was found. However, daily water loss was positively correlated with the hydroponic surface/fish tank volume ratio if the same experimental conditions and/or systems were compared. The plant species grown in hydroponics influenced the daily water loss in aquaponics, whereas no effect was exerted by the water flow (reciprocating flood/drain cycle or constant flow) or type (medium-based, floating or nutrient film technique) of hydroponics.
