Utilization of seafood processing waste as an adsorbent in the treatment of paint industry effluent in a fixed-bed column

摘要

The potentiality of seafood processing waste P. sanguinolentus (crab shell) as an adsorbent was assessed in fixed bed absorption (FBC) column for the treatment of paint industry effluent (PIE). The effect of bed height (10-25 cm), flow rate (5-15 cc/min) and initial concentration (3100-7693 mg/L) were studied with reference to the colour removal efficiency. Breakthrough curves were generated and based on the data the extent of suitability of different models was studied to identify limiting mechanism of the adsorption process. It was concluded that the intra particle diffusion was not the only rate controlling step, but film diffusion was also a likely influencing factor. The studies further indicated that P. sanguinolentus (crab) shell could be effectively used for PIE treatment.
