Investigation of Processes Used in the Treatment of Textile Industry Wastewaters
Abstract
One
of the most important harmful wastes threatening people and nature is textile
industry wastewaters. Colored textile wastewaters accumulating in water bodies
disrupts the aesthetic appearance of water and reduces light penetration to
water. Reduction of light penetration and dissolved oxygen causes the
extinction of living and limits the using of water sources. It is also known
that some dyes contains the toxical substances. Even in very small quantities,
colored textile wastewaters can spread to large water bodies since it has high
dispersion ratio. Colored textile wastewaters threatens to environment when it was
discharged without treatment. While adsorption, filtration and chemical
processes is preferred for color removal, biological activated sludge systems
are used the COD removal from colored wastewaters. Nowadays, membrane processes
having the character of nanotech textile has been started to use for more
effective treatment. When treatment alternatives compared with each other, it
was concluded that the Fenton processes more appropriate for COD and color
removal from textile wastewaters in comparison with other advanced oxidation
techniques. Membrane processes that find a wide application area in wastewater
treatment can make a great contribution to economy of industries discharging concentrated
waste. Moreover, membrane processes can reduce the pollution load to great extent.
According to researches, it is determined that the reverse osmosis and
nanofiltration membranes can be used successfully in treatment of textile
wastewaters. It is seen that clogging of nanofiltration membranes is very low
levels and efficiency of color removal can reach to very high values such as
95%.
