Investigation of Textile Wastewater Treatment by Electrocoagulation Process

Abstract

In this study, the basic mechanism of the Electrocoagulation (EC) process and the effects of operating parameters affecting the process on pollutant removal from textile wastewater are discussed. With the development of the textile industry, the concentrations of pollutants have increased and this has created various environmental problems. Textile wastewater is characterized by high suspended solids content, turbidity, chemical oxygen demand and color. There is a need for effective and efficient treatment processes before the resulting wastewater is discharged to the environment. EC has been widely used in the treatment of industrial wastewater in recent years due to its versatility, ease of installation and environmental friendliness. The energy requirement and the amount of sludge formed for the EC process are much less than other treatment processes. Due to such advantages, the use of EC in the treatment of textile wastewater is widely accepted.

Tekstil Atıksularının Elektrokoagülasyon Prosesiyle Arıtımının İncelenmesi

Abstract

Bu çalışmada, Elektrokoagülasyon (EC) prosesinin temel mekanizması, prosesi etkileyen işletme parametrelerinin tekstil atıksuyundan kirletici giderimi üzerine etkileri tartışılmıştır. Tekstil endüstrisinin gelişmesiyle beraber oluşan kirleticilerin konsantrasyonları artmış ve bu durum çeşitli çevresel problemler oluşturmuştur. Tekstil atıksuları, yüksek askıda katı madde içeriği, bulanıklık, kimyasal oksijen ihtiyacı ve renk ile karakterize edilir. Oluşan atıksuların çevreye deşarjı öncesi etkili ve verimli arıtma proseslerine ihtiyaç vardır. EC, çok yönlülüğü, kurulum kolaylığı ve çevre dostu olması nedeniyle son yıllarda endüstriyel atıksuların arıtılmasında yaygın olarak kullanılmaktadır. EC prosesi için enerji gereksinimi ve oluşan çamur miktarı diğer arıtma proseslerine göre çok daha azdır. Bu gibi avantajlarından dolayı EC nin tekstil atıksularının arıtımında kullanımı yaygın olarak kabul görmektedir.
