NanoKriti

At Kakinada, Andhra Pradesh, Nanokriti conducted a field trial to evaluate how nanobubble technology could improve dissolved oxygen management in shrimp aquaculture ponds. The Nanokriti Oxygen Nanobubble Generator was integrated into the existing pond system without major changes to infrastructure. The trial showed higher minimum dissolved oxygen levels, improved oxygen stability during critical low-oxygen periods, […]

Nanobubbles (NBs) are extremely small (typically 70–150 nm) gas cavities in liquid that exhibit unusual stability, high internal pressure, large surface-area-to-volume ratio, and strong surface charge. These unique properties greatly enhance gas–liquid mass transfer, NBs can dissolve far more gas in water than would be predicted by Henry’s Law, and under certain gas and operating […]

Nanobubbles (NBs) are gas-filled cavities in liquid, typically <1 µm in diameter. Unlike conventional bubbles, NBs exhibit extraordinary stability (lasting days or even months) due to their very small size and charged interfaces. They exist as surface NBs (on solid–liquid interfaces) or bulk NBs (spherical in liquid). NBs normally carry a negative zeta potential (−10 to […]

Nanobubbles (NBs) are ultrafine gas bubbles (~50–1000 nm diameter) in water that remain stable for days to months due to their low buoyancy and high surface charge (typically negative zeta potential from OH⁻ adsorption) and low buoyancy.  Their large surface area and ability to carry gases (O₂, H₂, O₃, etc.) make them attractive for medical hydrotherapy. […]

Nanobubbles (NBs), gas-filled cavities <1 μm diameter, have unique physical and chemical properties (exceptional stability, high surface area and negative charge) that can intensify conventional wastewater processes. In sewage systems, NBs (air, O₂, ozone or CO₂ gas) enhance oxygen transfer (higher kₗₐ and %O₂ transfer), accelerate organics and nutrient removal, and aid flotation/dewatering via coagulation or […]

Nanobubbles (NBs) are gas bubbles <200 nm in diameter, have unique physical properties (high internal pressure, large surface area, negative surface charge, and exceptional stability) that give them unusual gas–liquid mass-transfer characteristics. In wastewater systems, NB injection (typically of O₂ or O₃) can significantly enhance oxygen transfer efficiency (OTE) and pollutant removal. Research, Pilot, and full-scale […]

Nanobubbles (NBs), gaseous voids often less than 200 nm in size, have surfaced as a potential improvement to traditional dissolved-air flotation (DAF) methods. In contrast to traditional microbubbles (10–100 μm), NBs demonstrate an exceptionally high surface area, gradual ascent rates, prolonged stability, and charged surfaces (often with a zeta potential of –20 to –60 mV). Nanoparticles quickly […]

Nanobubble (NB) technology harnesses ultra-fine gas bubbles (<1 µm) to boost oxidation, aeration and flotation in water treatment. Pilot and full-scale studies have demonstrated that oxygen nanobubble aeration can significantly improve dissolved oxygen levels, oxygen transfer efficiency, and biological treatment performance. Compared with conventional aeration, nanobubble systems have been reported to achieve higher BOD and COD […]

Nanobubbles (NBs), gas-filled cavities < 200 nm in water, have unique physicochemical properties (high surface area, surface charge, long stability) that can boost plant growth and resource-use efficiency. Studies report enhanced seed germination, root growth and yields with NB-treated irrigation. Studies have reported substantial improvements in seed germination following nanobubble irrigation, similar studies have also […]

Injecting nanobubbles into culture media can significantly improve microalgae cultivation by enhancing gas transfer, mixing, and process stability. Nanobubbles are ultra-fine gas bubbles (approximately 50–200 nm). Because of their extremely small size, they provide a very high gas–liquid interfacial area and long residence time, which can substantially increase CO₂ and O₂ mass transfer coefficients (kLa) […]
