Abstract

This study aimed to determine the effects of three different high molecular weight (HMW) flocculants (anionic, cationic and non-ionic
flocculants) on the fine particles removal from natural stone (foid-bearing rock) processing plant wastewater at alkaline pH conditions.
The test results were investigated in terms of turbidity values depending on pH of the medium, flocculant concentration and time (0–60
min). According to the results obtained, the turbidity values of the wastewater in the absence of the flocculants were pH dependent and
decreased as the pH increased, resulted in the minimum turbidity values at pH 12. In the presence of the flocculants, the pH depended
turbidity removal efficiencies varied with flocculant type, flocculant concentration and time. The best results were obtained at highly
alkaline pH values (pH 12) with the turbidity removal efficiency of ≤99% in the presence of non-ionic flocculant. In the case of anionic
and cationic flocculants, the minimum turbidity values were also obtained at pH 12 with turbidity removal efficiencies over 90%.
