Purification of Distillery Spent Wash by Using Activated Charcoal
Purification of distillery spent wash using activated charcoal has great potential as a sustainable method as it is cost effective method. The purpose of this investigation is to study the activated charcoal purification method for purification of distillery spent wash. For this, the study encompassing evaluation of reduction of various physical chemical parameters (pH, COD, TS, TDS, Ca, Mg, Na and K) of distillery spent wash was done by passing it through the activated charcoal column. The distillery spent wash was acidic (pH 4.7) and dark brown in color which often cause psychological fear in farmers for its utilization. Activated charcoal purification of distillery spent wash exhibited maximum reduction in COD (48.98%), TS (64%), TDS (55.26%), Mg (78.03%), Na (60%), Ca (80.91%), K (75.30%) and increase in pH toward pH 7. Purified distillery spent wash showed a good growth of wheat seeds
