Treatment of distillery spent wash by adsorption technique has great potential as a sustainable method as it isa low cost method. The aim of this investigation is to study the impact of different textures of soil, sand and active carbon asadsorbent for spent wash purification. For this, the study encompassing evaluation of reduction of various physical chemicalparameters (Color, Odor, pH, COD, TS, TDS, Ca, Mg, Na and K) of distillery spent wash was checked by passing it throughthe columns of soil, sand, active carbon, soil+sand (1:1), soil+active carbon(1:1) and sand+active carbon(1:1). The originaldistillery spent wash was acidic (pH 4.7) and dark black brown in color with foul smell. It creates psychological fear infarmers in its utilization for irrigation. After 72 hour treatment of spent wash, maximum reduction in its physico chemicalproperties (COD, TS, TDS, Mg, Na, Ca,) is observed with active carbon and increase in pH toward pH 7, followed bysoil+active carbon (1:1). Treated spent wash has resulted a good growth of wheat seeds when used for irrigation andreduced demand of chemical fertilizers.
