||Described are observations from preliminary studies and pilot plant operations that were initiated to upgrade the waste effluent of an integrated textile dye mill. The biological pilot plant was designed to use activated carbon on the basis that the presence of carbon enhances bio-degradation. To meet the proposed water standards, tertiary treatment of the effluent was also necessary. Two methods of attaining better water effluent were investigated. A conventional method, the addition of an alum system, with alum recovery was added to the biological treatment system. Although the effluent quality improved, trace color remained in the supernatant. An adsorbent resin system was tested and found effective in upgrading the waste effluent to recreational standards. The results of preliminary studies and the pilot plant indicate that carbon catalysis enhances biological degradation, and satisfactory tertiary treatment can be achieved with an alum and resin system.
