Abstract

The
textile industry uses high amount of water and generates wastewater that
requires effective wastewater treatment technologies. Textile industry in
Turkey is an advanced industry particularly in Bursa. During the dying process
of fabrics and the fibres a lot of water, synthetic dyes and various chemicals
are used, and consequently wastewater is produced that contains complex
pollutants with different chemical structure. In particular, dyes that have
high water solubility and low fixation rates hydrolyse before they are fully
fixed, which results in high amount of waste dye. Decreased light permeability due to
the colour caused by the waste dye prevents photosynthetic activities and
oxygen depletion occurs. Furthermore, the presence of toxic and mutagenic dyes
in water bodies adversely affect aquatic life. Releasing them into the sewage
system without treatment can cause problems in biological processes of urban
wastewater treatment plants. Therefore, there is a need for innovative, cost
effective and efficient wastewater treatment technologies for the treatment of
wastewater containing dyes before they are released to the water systems.
Electrocoagulation is known to be an effective method especially in colour
removal from textile industry wastewaters. In this study, as an effective
method for colour removal from waters electrocoagulation was applied to a disperse
dye (Disperse Blue 79), which is in a colloid form in a dye solution, and to a
reactive dye (Reactive Yellow 160), which has an anionic character and is
dissolved in water. After a 10 minutes experiment period with 0.1 A current
intensity %92.45 color removal rate was obtained for Disperse Blue 79 whereas
for the Reactive yellow 160 color removal rate was only %54.84. Study results
shows the importance of dye type in color removal with electrocoagulation
method.

Abstract

Tekstil endüstrisi yüksek
miktarda su ihtiyacı ve atıksu üretimi açısından etkili su arıtım
teknolojilerine ihtiyaç duyan bir endüstridir. Türkiye’de özellikle Bursa’da
tekstil endüstrisi gelişmiş durumdadır. Tekstil üretiminde kumaşların veya
kumaşta kullanılan liflerin boyanması sırasında çok miktarda su, sentetik boya
ve çeşitli kimyasallar kullanılır ve bunun sonucunda farklı molekül yapılarında
kompleks kirleticileri içeren atıksu meydana gelir. Özellikle suda çözünürlüğü
yüksek ve sabitlenme oranları düşük olan boyar maddeler uygulama sırasında
tamamen tutunmadan hidrolize olmaları nedeniyle çok miktarda tutunmamış boya
atık haline gelir. Alıcı su ortamında atık boyanın oluşturacağı renk nedeniyle
ışık geçirgenliği azalarak fotosentez faaliyetleri engellenir ve oksijen
tükenmesi meydana gelir. Ayrıca toksik ve mutajenik boyar maddelerin su
kütlelerinde bulunmaları sucul yaşamı olumsuz etkiler. Kanalizasyon sistemine
arıtılmadan bırakılmaları kentsel atıksu arıtma tesislerinin biyolojik proseslerinde
sorunlara yol açabilir. Bu nedenle boyar madde içeren atıksuların su
sistemlerine bırakılmadan önce arıtılmaları için yenilikçi, uygun maliyetli ve
etkili atıksu artım teknolojilerine ihtiyaç vardır. Elektrokoagülasyon tekstil
endüstrisi atıksularında özellikle renk gideriminde etkili bir yöntem olarak
bilinmektedir. Bu çalışmada sulardan renk gideriminde etkili bir yöntem olan
elektrokoagülasyonun aynı çalışma şartlarında boya banyolarında kolloidal
olarak bulunan dispers boyaya (Disperse Blue 79) ve boya banyosunda çözünmüş ve
anyonik karakterdeki reaktif boyaya (Reactive Yellow 160) uygulandı. Çalışma
sonuçlarından 0,1 Amper akım şiddeti ve 10 dakikalık deney süresi sonunda
Disperse Blue 79 boyası % 92.45 oranında giderilirken Reactive Yellow 160
boyası ancak % 54,84 oranında giderildi. Bu sonuç bize elektrokoagülasyon
yöntemi ile renk gideriminde boya türünün ne kadar etkili olabildiğini
göstermektedir.
