Abstract: Recovery of hydrofluoric acid (HF) from waste semiconductor acid solution by ion exchange was investigated. Strong base anionic and strong acid cationic ion exchange resins were involved in the recovery process. The former ...

Abstract: A continuous process of combined ozonation and chemical coagulation was employed for treatment of textile wastewaters from several dyeing and finishing plants. Ozonation was found to be highly effective in color removal ...

Abstract: Treatment of high-strength desizing wastewater obtained from a textile dyeing and finishing plant by wet air oxidation (WAO) is studied. Experiments were conducted to investigate the effects of the operating pressure, ...

Abstract: Experiments have been conducted to investigate gas-phase adsorption characteristics of 1,1,1,2-tetrafluoroethane (HFC-134a) by activated carbon fiber, extruded activated carbon, granular activated carbon, activated alumina, ...

Abstract: Theoretical and experimental investigations have been conducted on the adsorption characteristics of benzene, toluene, ethylbenzene, and xylene (BTEX) by macroreticular resins. A theoretical model is proposed for describing ...

Abstract: A novel method is proposed in this study for determining the dissolved oxygen (DO) diffusion coefficient in industrial wastewaters. The method is based on the principle of measuring the average DO concentration during the ...
