flocculation

This study focuses on optimizing the coagulation-flocculation process for treating pollutants in the leachate from Azzaba landfill, utilizing natural coagulants: walnut shells, Moringa oleifera seeds, and Opuntia ficus-indica leaves. Walnut shells, at pH 4, a coagulant dosage of 12g/L, 300rpm stirring speed, and 25 minutes of treatment, demonstrated remarkable reductions in turbidity (83.92%) and suspended solids (92%).

This article discusses the issue of sludge water treatment generated in the production of ceramic sanitary ware. Experimental studies were conducted on the effectiveness of physical and chemical treatment methods, in particular the use of coagulants (aluminium sulphate) and flocculants of various types (anionic, non-ionic, cationic). The optimal parameters for water treatment have been determined, which allow for the maximum removal of suspended particles and minimise the formation of sediment.
