“…As aquaponics is a relatively young discipline, most of the existing research is focused at the system levelfor example, studies evaluating the technical integration of aquaculture with hydroponics in different configurations (Fang et al 2017;Lastiri et al 2018;. Whilst individual aquaponic system components and their interactions can still be further optimized for productivity, their performance within a controlled environment envelope has not been comprehensively addressed.…”

“…The synergistic activity of algae and prokaryotes can be used to improve the efficiency of algae biological wastewater treatment, especially regarding nitrogen removal (Wang et al 2018). Moreover, some studies have shown that the bacteria-algae composite system in sewage treatment plant can significantly improve the yield of biofertilizer and make full use of the resources in wastewater (Fang et al 2017;Tang et al 2018). In addition, some scholars have studied the process of treating sewage with bacteria and algae system.…”

Water pollution is mainly caused by chemical pollution, especially inorganic and organic pollutants, including toxic metals and metalloids as well as various synthetic or organic chemicals. Marine algae have good adsorption capacity for heavy metals such as As, Zn, Cu, Cd, Pb et.al in polluted water, and can also have certain removal ability for pollutants such as nitrogen and phosphorus in sewage. This paper reviews the current application status of wastewater treatment and the mechanism and application of marine algae in wastewater treatment, aiming at providing reference for further research and development of marine algae in wastewater treatment.

“…Microbial communities in the biofilter, membrane surface, sedimentation tank sludge zone, and mechanical filter media are involved in biological processes under both aerobic and anoxic conditions . Attached-growth biofilters are typically used due to their high stability and simplicity in operation. − Microbial communities in the biofilter vary with aerobic and anoxic conditions; the environments in the system can be controlled to some extent by adjusting operating parameters (e.g., pH levels, dissolved oxygen (DO) concentrations, and hydraulic loading rates (HLR)). , However, even when air is supplied to the biofilter, anoxic conditions may prevail in the inner part of the biofilm because of the poor mass transfer of oxygen . Often an important factor, plant roots in the hydroponic grow bed provide an ideal setting to optimize plant-microbe symbioses to promote nitrogen uptake, plant growth, and ultimately nitrogen recovery.…”

“…Nitrogen transformations in aquaponic–bioponic systems are biologically driven processes (Figure ). ,− , For example, in aquaculture, fish metabolizes the proteins and other compounds in the feed for their energy and growth needs, excreting the residual nitrogen as wastes in soluble and solid forms. Freshwater fish assimilate ∼25% of ingested nitrogen; the remaining nitrogen is excreted through the gills as TAN (∼60%) and in the feces as organic nitrogen (∼15%) .…”

Nitrogen, a critically important nutrient that boosts yields in agriculture and food production, is currently overused to meet the rising demand for food. Surplus nitrogen ends up in the environment in excess of the capacity of natural nitrogen cycle, thereby leading to serious environmental pollutions, such as eutrophication of water bodies and emission of nitrous oxide (a highly potent greenhouse gas) to atmosphere. Aquaponics− bioponics is an emerging soilless technology for nitrogen recovery that links organic vegetable production to aquaculture effluent remediation (aquaponics) or organic waste recycling (bioponics). This Review presents the concept of aquaponics−bioponics for nitrogen recovery. Nitrogen transformations and nitrogen mass distributions in aquaponic−bioponic systems are critically discussed, along with the nutrient availability of several organic composts that can be integrated with the systems, and the microbial communities involved. This discussion is followed by a dynamic nitrogen modeling for managing nitrogen from different wastes in aquaponics−bioponics. Various emerging engineering technologies that could improve aquaponics−bioponics are presented, including aeration with microbubbles and/or nanobubbles, cocultivation with algae, process automation with Internet of Things, and integration with indoor vertical farming (plant factory with artificial light). Overall, the Review lays out the state-of-art in aquaponics−bioponics and highlights potential approaches for developing highly efficient nitrogen recovery technologies from diverse organic waste streams.
