Mixed streams wastewater treatment using adsorption.

Mixed samples prepared from known pure solutes are reported to have synergetic efforts with respect to single solute and multi-solute adsorption. Attempt is made to extend the theory of enhancement ratios to the mixed stream wastewater samples collected from dyes manufacturing industries. Synergetic effect of the multi-solutes as well as of mixture of adsorbents is observed for mixed streams of wastewater samples, containing a number of pollutants, on given inexpensive adsorbents. The Rathi Puranik model developed for single wastewater streams can be extended to the mixed stream wastewater samples using the rate of COD reduction prediction. The concept of average apparent enhancement factor is discussed.
