PURIFICATION OF PHENOL-CONTAINING WASTEWATER

Treatment of Wastewater Containing High Concentration of Phenol & Total Dissolved Solids in Moving Bed Biofilm Reactor

Many industries generate phenolic wastewater of acidic nature. Neutralization with sodium hydroxide generates the phenolic wastewater with high TDS. Both phenol and ionic concentration of TDS are inhibitor to biological treatment processes. A study was carried out for biological treatment of phenolic wastewater with high total dissolved solid (TDS) concentration in moving bed biofilm reactor (M...

Synthesis and Application of Functionalized Carbon Nanotube Infused Polymer Membrane (fCNT/PSF/PVA) for Treatment of Phenol-Containing Wastewater

In this study, polymer composite membranes comprising carbon nanotube (CNT), polysulfone (PSF) and polyvinyl alcohol (PVA) were synthesized via the phase inversion method and used to remove phenol from the phenol-containing wastewater. The fabricated membranes were reinforced with the functionalized carbon nanotubes (fCNTs) and coated with PVA to enhance their mechanical strength and anti-fouli...

Industrial Process and Wastewater Purification

Anaerobic treatment of phenol in wastewater under thermophilic condition.

Over 99% of phenol was effectively degraded in an upflow anaerobic sludge blanket (UASB) reactor at 55 degrees C with 40 h of hydraulic retention time (HRT) for a wastewater containing 630 mg/L of phenol, corresponding to 1500 mg/L of chemical oxygen demand (COD) and a loading rate of 0.9 g-COD/L/d. The maximum specific methanogenic activity (SMA) of the phenol-degrading sludge was 0.09 g-CH4-C...

Study on Treatment Methods of Phenol in industrial Wastewater

Li Si, Kong Ruixue, Sun Lin, Li Sifan, Yang Shuangchun* (Liaoning Shihua University. Fushun, Liaoning, China. 113001) Abstract—Industrial wastewater is a kind of wastewater that generate in the industrial production process. The wastewater from refining and coal carbonization contains high concentration of phenols pollutants. In this paper, study on phenol treatment methods in industrial wastew...
