In recent years, there has been growing interest in the varied applications of nanobubble technology. Given their unique physicochemical properties, such as minuscule size (< 1 µm), surface charge, and high internal pressure, nanobubbles (NB) could provide new opportunities fields environmental engineering (including remediation, water treatment, aerobic fermentation, anaerobic digestion, algal biomass production), agriculture agronomy, horticulture, aquaculture, aquaponics, bioponics,...
Microbubbles (MBs) and nanobubbles (NBs) refer to bubbles of micrometer nanometer sizes. Due several unique attributes, including long-term stability, negative surface charge, the ability generate reactive oxygen species, MB NB technology has garnered significant attention in water wastewater treatment ecological restoration. Recently, studies have shown beneficial effects MBs NBs membrane defouling, pathogen deactivation, environmental remediation, etc. However, there is limited knowledge...
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 environment excess of capacity natural cycle, thereby leading serious environmental pollutions, such as eutrophication water bodies emission nitrous oxide (a highly potent greenhouse gas) atmosphere. Aquaponics–bioponics an emerging soilless technology recovery links organic vegetable production aquaculture...
Aquaponics is a climate-smart food production system that relies on nutrient recovery from aquaculture effluent. The availability of dissolved oxygen (DO) limits the performance aquaponic systems. To address this issue, air micronanobubbles (MNBs) were tested as an alternative aeration method. Due to their small size (<50 μm) and long-term stability, MNBs can enhance gas–liquid mass transfer maintain DO concentrations above saturation, enhancing aerobic biochemical processes. Through 16S...
