There are many technologies available for treating wastewater from the textile industry. Included are (1) biological treatment, (2) chemical precipitation, (3) carbon absorption, (4) ultrafiltration, and (5) oxidation with ozone. The main drawback of these technologies is that they generally lack the broad scope of treatment efficiency required to reduce all types of pollutants present in textile wastewater. However, when one approach does look promising, its capital costs or operating costs often become prohibitive when applied to the large water needs common to this industry. It has recently been shown that an electrochemical technology developed in the 1970s by Andco Environmental Processes, Inc. effectively removes many of the contaminants including toxic dye species and heavy metals along with significant BOD and COD reduction across many types of textile wastewater and dye species. The removal of dyes and other pollutants in textile wastewater can be accomplished very efficiently with the electrochemical process. Actual operating data, along with actual water samples, will be presented along with economics and operating characteristics of this type of a system. Additional considerations such as removal of other components such as BOD and COD, theoretical interpretations, and the possibility of water reuse will also be discussed.
