Abstract :
The haloacetonitriles (HANs) exist in drinking water exclusively as byproducts of disinfection. HANs are found in drinking water more often with higher concentrations. Human exposure occurs through consumption of finished drinking water, oral and dermal contact as well as when showering, swimming and other activities. The purpose of this study was to investigate the novel hybrid adsorption/ PBS membrane filtration process used to remove haloacetonitriles from aqueous solution. The efficiency of the PAC adsorbent was also evaluated at different pH, which confirmed efficacy of PAC at pH of 8. A maximum removal of DOC (98.7%) was obtained with 150 mg/L PAC dosage at a solution pH of 8. HANs sorption process followed the pseudo second order kinetic model and the Langmuir isotherm gave the best correlation of adsorption.
