Flotasyon prosesi mineral işlemede uygulanan yerçekimi ile bir ayırma (yüzdürme) işlemidir. Son yıllarda su ve atıksu arıtmında yaygın olarak kirleticilerin ayrımında kullanılmaktadır. Flotasyon prosesleri üretilen kabarcık metoduna göre isimlendirilir. Örneğin; dağılmış-hava flotasyonu, çözünmüş-hava flotasyonu ve son yıllarda elektrokimyasal arıtma proseslerinden biri olan elektroflotasyon (Ef) verilebilir. Bu çalışmada literatür araştırmsı yapılmış ve Ef prosesinin su, ağır metal, organik ve inorganik kirleticilerin, yağ ve ürünlerinin, boyar maddelerin, deterjanların, vb. kirleticilerin gideriminde uygulanması ile elde edilen sonuçlara odaklanılmıştır. Bu çalışmaların sonuçlarına göre; Ef prosesinin sağladığı bazı avantajlar sayesinde su ve atıksu arıtımında ayrıca suyun geri kazanımında tatmin edici sonuçlar elde edilmiştir.

ELECTROFLOTATION PROCESS IN WATER AND WASTEWATER TREATMENT

Öz

The flotation process is a gravitational separation (flotation) process applied in mineral processing. In recent years, water and wastewater treatment is widely used in the separation of pollutants. Flotation processes are named according to the bubble method produced. For example; dispersed-air flotation, dissolved-air flotation and electroflotation (Ef), one of the electrochemical treatment processes in recent years, can be given. In this study, electroflotation process of water, heavy metal, organic and inorganic pollutants, oil and products, dyes, detergents, etc. The results obtained by applying the removal of pollutants were focused on. In the results of these studies, some advantages of electroflotation process have provided satisfactory results in water and wastewater treatment or water recovery.
