City size flows of hot and very caustic, interestingly colored wastewater are quite common in the textile industry. The many non-degradable organics in its wastewater pose a particular risk to the marine environment.
Specific knowhow is required to remove colors, as most dyes escape conventional wastewater treatment and persist in the environment as a result of their high chemical stability. In addition, anti-microbial agents resistant to biological degradation are frequently used in the manufacture of textiles. The synthetic origin and complex aromatic structure of these agents make them more recalcitrant to biodegradation.
Colubris has a number of processes that are tailored specifically to the treatment of textile effluents, such as its innovative UA(SB)²- and FBR processes, flue gas pH correction and a host of advanced color removal processes.
