The aim of this study is the removal of color and pathogenic bacteria from Dyeing effluent by different adsorbents such as water hyacinth, sugarcane pulp and coconut pulp. From this experiment we investigate that all adsorbents were active in removal of color from effluent. COD values were higher than the recommended value and the viable bacteria (TVBC) were found in all sample. The lowest value of Total Viable Bacteria Count (TVBC) was 4× and the highest value was 7×. The lowest value of Total Coliform Count (TCC) was 0 and highest value was 6×. The lowest value of Fecal Coliform Count (TFCC) is 0 and highest value was 6×. From this experiment we investigate that TCC and TFCC was not found in any sample treated by water hyacinth. So this experiment suggests that water hyacinth was a suitable adsorbent on the basis of removal of color and the hazardous bacteria.
