Biju G.
10 Sep 0 0

extile wastewater purification:

The textile industry is rated as one of the most polluting and chemically intensive industrial sectors (Uzal, 2015).

-Chemicals like acids, alkalis, colours, high BOD/COD concentration, surfactants, dispersing agents, soap, pigments, and metals are contained in effluent wastewater (Paul et al., 2012)

- dye contents can be as high as 200 mg/L), and many dyes are visible in the water at concentrations as low as 1 mg/L (Cervantes, 2009).

Challenge: Difficult to decolourize-  Dyes usually are stable chemicals,(complex structure and synthetic origin)

Biological treatment: beneficial

Azo dyes can be degraded by - fungus (P. Chrysosporium) but show slow kinetics

                      - Bacteria Bacillus sp. OY1-2 deposited by the laboratory of microbial engineering (No. 13118) shown to be efficient in degrading Azo dyes
