Untapped Potential: Applying Microbubble and Nanobubble Technology in Water and Wastewater Treatment and Ecological Restoration

ACS ES&T Engineering, Journal Year: 2022, Volume and Issue: 2(9), P. 1558 - 1573

Published: Aug. 9, 2022

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 physical biochemical interactions between microbial communities; mechanistic roles on micropollutants removal during aerobic anaerobic digestion; engineering limitations versatility scalability technology, among others. This review fills this gap by providing a systematic discussion fundamentals NBs, their size concentration, physicochemical properties, generation methods. The latest advances applications restoration are then critically discussed. thus identifies challenges implementing concludes with future research directions for broader understanding technology.

Ozone Micronano-bubble-Enhanced Selective Degradation of Oxytetracycline from Production Wastewater: The Overlooked Singlet Oxygen Oxidation

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 57(47), P. 18550 - 18562

Published: Dec. 7, 2022

The efficient and selective removal of refractory antibiotics from high-strength antibiotic production wastewater is crucial but remains a substantial challenge. In this study, novel ozone micronano-bubble (MNB)-enhanced treatment system was constructed for treatment. Compared with conventional ozone, MNBs exhibit excellent efficiency oxytetracycline (OTC) degradation toxicity decrease. Notably, study identifies the overlooked singlet oxygen (1O2) first time as active species in MNB through probe electron paramagnetic resonance methods. Subsequently, oxidation mechanisms OTC by are systematically investigated. Owing to high reactivity toward 1O2, enhance anti-interference performance raw complex matrixes. This provides insights into mechanism MNB-enhanced pollutant new perspective high-concentration industrial using MNBs. addition, presents promising technology scientific guidance wastewater.
