Abstract :
Progress in dyes & intermediates industry requires to find the solution of problem i.e. effluent having high COD level. Primary & secondary treatment like aeration is generally followed. But, COD reduction rate is small at tertiary level. This study gives COD reduction in metanilic acid effluent by adsorption by using activated carbon & lignite powder. With this adsorbents experiments were done for COD reduction which depends upon two factors, time of adsorption & concentration of adsorbent . COD reduction will differ with time & concentration of adsorbents. One more thing to be taken is the effect of adsorbent on sample, before & after neutralization. Process is divided in stages. Comparison is done for COD reduction for both adsorbents. Taking 1% & 2% concentration for both adsorbent. Stage wise operation showed low concentration of adsorbent gives higher COD reduction. The details are further shown.
