(INETI), Portugal Abstract An enzymatic cocktail was used for the decolorization of process
wastewater, containing mainly three reactive azo dyes, from a textile dyeing and printing
company. Water sampled from different processing streams and combinations thereof was
decolorized to different extents. The decolorization was greatest for C.I. Reactive Black 5,
followed by C.I. Reactive Red 158, whereas C.I. Reactive Yellow 27 was the least
decolorized. As wastewater from the printing process was inhibitory, the 1 mistirred tank
type reactor prototype was installed near the outlet prior to the discharge of wastewater from
the printing process. Temperature and pH control systems were installed to ensure optimal
enzymatic decolorization, this being about 45 ° C and pH 6.4. The average temperature
observed at the reactor was 42.1 ° C, which indicated the need for improved temperature
control. Laboratory scale tests were done to assess the reuseability of the biotreated
wastewater for the washing of dyed cotton fabrics.
