Biotreatment of textile wastewater with continuous biofilter solutions and the associated microflora
C
olors are very important in our lives; we express ourselves by the design of our clothes and shape our homes with colored
textiles. We have several demands on the fabrics in our surroundings; we want them to durable against washing, sunlight,
enzymes and ageing. Though, we give little thought on their impact on environment. With a few exceptions, extracting intense
color from natural sources is quite rare. However, chemists started to develop dyes in mid-1800, which gave rise to the chemical
industry. Today, most colors are manufactured synthetically and the major classes are azo and anthraquinone dyes. The process
of dyeing is usually performed in water, with part of the dye inevitably ending up in the water. Textile dying processes pollute
wastewater with recalcitrant azo and anthraquinones dyes. There is a need development of effective and affordable degradation
systems for textile wastewater applicable in countries. We have worked with biodegradation of artificial and actual textile
wastewaters in different biofilter solutions with carriers such as wood and rice husks. Degradation performances have been
analyzed by spectrophotometry and liquid chromatography coupled with mass spectrometry. Constructed biofilter have
performed over 90% decolorization with hydraulic retention times, roughly between 28-67 h. Molecular fingerprinting analysis
(DGGEand16S rRNAsequencing) revealedadiverse anddynamicbacterial communitycomposition involved. Several identified
bacteria in the consortium are known to carry azoreductase genes, such as
Dysgonomonas,
and
Pseudomonas
. Furthermore
fungal internal transcribed spacer (ITS) gene fragments in the biofilters revealed the presence of fungal phylotypes such as
Gibberella
and
Fusarium
. Our findings emphasize that rice husk biofilters support a microbial community of both bacteria
and fungi with key features for biodegradation of actual textile wastewater. These results suggest that microbial processes can
substantially contribute to efficient and reliable degradation of actual textile wastewater.
Biography
Jörgen Forss has his expertise in biotechnical applications where different microorganisms are used to design wastewater solutions for industrial effluents. He has designed
sustainable and cost efficient biofilters to treat wastewater from textile industries in development countries. He has worked both with white rot fungi and bacteria applications
where microorganisms were employed in different designs and molecular fingerprinting was used to follow the microbial community composition and metabolites was analyzed
with liquid chromatography coupled with mass spectroscopy (LC/MS). He has a strong belief that natural microorganisms possess all the necessary characteristics needed
to degrade most compounds and circulate nutrients, if we can design the right environment for them.
