Abstract

Bu
çalışmada, askıda tane içeren sentetik atıksuya flokülasyon yöntemi uygulanmıştır.
Deneylerde flokülant olarak poliakrilamid esaslı anyonik, katyonik ve noniyonik
sentetik organik polimerler kullanılmıştır. Flokülasyon deneyleri altı
pervanesi olan jar (kavanoz) test cihazında yapılmıştır. Flokülant tipi,
flokülant mol ağırlığı, flokülant dozajı, süspansiyon pH’sı ve karıştırma hızı
gibi bazı parametrelerin bulanıklık giderimi üzerine etkileri belirlenmiştir. Yüksek
molekül ağırlıklı anyonik flokülant ile en iyi sonuç, %98,9 bulanıklık giderim
verimi olarak elde edilmiştir.

Removal Of Suspended Partıcles From Wastewater Usıng Flocculatıon Method

Abstract

In
this study, flocculation method was applied to synthetic wastewater containing suspended
particles. In the experiments, polyacrlamide-based anionic, cationic and
nonionic synthetic flocculants were used. Flocculation tests were carried out
at jar test apparatus with six mixing paddles. The effects of some parameters
such as flocculant type, molecular weight of flocculant, flocculant dosage, pH
of suspension and rapid mixing speed on the turbidity removal efficiency were
determined. The best result was obtained as 98,9 % turbidity removal efficiency
by using anionic flocculant having high molecular weight.
