Comparative evaluation of natural adsorbent for pollutants removal from distillery spent wash

摘要

Adsorption capacity of three different adsorbents (activated charcoal, fly ash and wood ash) has been tested and compared for the removal of various pollutants and heavy metals from distillery-spent wash. Adsorption was brought about at polyhouse conditions and the changes in pH, colour, COD, TS, TDS, TSS, Ca, Mg, Na, K and heavy metals (Cu, Zn, Fe) of distillery effluent using various adsorbents has been examined. Activated charcoal was found to be best adsorbent followed by fly ash and wood ash.
