Abstract

Flocculation and flotation methods have been applied individually to achieve removal of suspended particles from wastewater. However, in this study, floc-flotation method where these two methods are applied together in mechanically agitated cell and the use of a combinations of different type surfactant and polymer to achieve floatability of fine particles are investigated. The conventional and floc-flotation experiments were carried out to determine effect of different parameters such as collector type and dosage, pH, flotation time, condition time and polymer/surfactant interactions on floatability of very fine particles. When the results of floc-flotation and conventional flotation were compared, it has been found that higher floatability values were achieved with floc flotation. It can be obtained 96.8% floatability of particles in presence of anionic surfactant (Aero 845, 750 g/t) and nonionic polymer (SPP N 134, 30 g/t) at pH 8 and 5 min. conditioning time for 5 min. flotation time by floc flotation in mechanical cell.

Özet

Flokülasyon ve flotasyon yöntemleri, atıksulardan süspanse tanelerin uzaklaştırılmasında ayrı ayrı uygulanan yöntemlerdir. Bununla birlikte bu çalışmada mekanik flotasyon hücresinde bu iki yöntemin birlikte uygulandığı flok flotasyonu yöntemi ve ince tanelerin yüzebilirliğini sağlamak için farkı tip toplayıcı ve polimer kombinasyonlarının kullanılması araştırılmıştır. Klasik flotasyon ve flok-flotasyonu deneyleri, toplayıcı tipi ve dozajı, pH, flotasyon süresi, koşullandırma süresi ve polimer/ toplayıcı etkileşimleri gibi parametrelerin ince tanelerin yüzebilirliği üzerine etkilerini belirlemek için yürütülmüştür. Klasik ve flok-flotasyonu deney sonuçları karşılaştırıldığında, flok-flotasyonu ile çok daha yüksek yüzdürme değerlerine ulaşıldığı bulunmuştur. Mekanik hücrede flok-flotasyonu ile pH 8’de 5 dakika koşullandırma ve 5 dakika flotasyon süreleri için anyonik toplayıcı (Aero 845, 750 g/t) ve iyonlaşmayan polimer (SPP N 134, 30 g/t) kombinasyonunda tanelerin yüzdürme verimi %96.8 olarak elde edilmiştir.
