Generation Mechanism of Hydroxyl Free Radicals in Micro–Nanobubbles Water and Its Prospect in Drinking Water

Processes, Год журнала: 2024, Номер 12(4), С. 683 - 683

Micro–nanobubbles (MNBs) can generate ·OH in situ, which provides a new idea for the safe and efficient removal of pollutants water supply systems. However, due to difficulty obtaining stable MNBs, generation efficiency is low, cannot be guaranteed. This paper reviews application research MNB technology security from three aspects: process MNBs water, rule during collapse, control mechanisms on biofilms. We found that methods are divided into chemical mechanical (about 10 kinds) categories, instability bubble size restricts technology. The by affected pH, gas source, size, temperature, external stimulation. And pH stimulus have more influence situ than other factors. Adjusting alkaline or acidic conditions selecting ozone oxygen as source promote generation. collapse also releases large amount energy, temperature pressure reach 3000 K 5 Gpa, respectively, making it remove ≈90% (i.e., trichloroethylene, benzene, chlorobenzene). biofilm removed physical, chemical, thermal effects. has great potential drinking applied improve quality, optimize household purifiers, enhance taste bottled water. Under premise safety, after letting people different ages samples, we compared with ordinary 85.7% think softer, 73.3% sweeter. further proves prospect applications. review innovative theoretical support solving problem safety.

Improving organic matter and nutrients removal and minimizing sludge production in landfill leachate pre-treatment by Fenton process through a comprehensive response surface methodology approach

Journal of Environmental Management, Год журнала: 2023, Номер 340, С. 117950 - 117950

Опубликована: Апрель 22, 2023

Landfill leachate (LL) represents a very complex effluent difficult to treat and manage which usually requires chemical pre-treatment. In this study, response surface methodology (RSM) was used identify the optimum operating conditions of Fenton process as pre-treatment LL in order reduce high organic content simultaneously optimize BOD5:TN:TP ratio. The dosages reagents, namely Fe2+ H2O2, were variables for implementation RSM. Chemical oxygen demand (COD), five-days biochemical (BOD5), total nitrogen (TN), phosphorus (TP) removals (and ratio), sludge-to-iron ratio (SIR) removal-to-sludge (ORSR) selected target responses. This approach considered SIR ORSR parameters are useful tool assessing sludge formation during along with matter removal. (H2O2 concentrations) significantly affected responses, role oxidation mechanism is dominant respect coagulation one. pH fixed 2.8 while treatment time set 2 h. operational obtained by perturbation 3D plot, found be 4262 mg/L 5104 respectively (H2O2/Fe2+ molar = 2) COD, BOD5, TN TP 70%, 67%, 84% 96% respectively, final values 1.15 L/mol 33.79 g/L accordance models-predicted values. Moreover, initial unbalanced (9:1:1) improved (100:6:1), making suitable subsequent biological treatment. investigated allowed removal load nutrients well minimize process, providing operation management
