PHENOL REMOVAL USING NON-IONIC RESIN BED FROM INDUSTRIAL WASTE WATER

ENVIRONMENT ENGINEERING

Experiments have been conducted to examine the liquid-phase adsorption of phenol from industrial wastewater by Nonionic Resin Bed (XAD-4), a polystyrene-divinylbenzene resin without a functional group, were carried out under different conditions. Experiments were carried out for the analysis of adsorption equilibrium capacities. Results of Laboratory experiments indicated that Non-ion Resin Bed had the highest rate of adsorption among the adsorbents studied and therefore more detailed studies were carried out with this adsorbent. The influence of particle size, temperature, and thermal regeneration on adsorption of phenol by Non-ion Resin Bed was evaluated. From particle size experiments it appeared that adsorption capacity of Resin Bed did not change by changing the particle size, but the rate of adsorption decreased with the number of Resin beds. The effect of temperature on adsorption was studied by determining equilibrium isotherms for Non-ion Resin Bed at 25 and 40°C. The results showed that adsorption capacity for Phenol by Non-ion resin bed was 99.8 %.it’s also very effective for BOD and COD for the industrial waste water containing phenol.
