natural coagulants

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%).

The provision of quality drinking water is one of the most important conditions for public health, especially in urban areas. Like many other settlements, the city of Mykolaiv faces problems with the quality of water supplied to consumers. This study evaluated some bacteriological parameters of drinking water supplied from different sources in the city and conducted a comparative analysis of the effectiveness of using plant coagulants for disinfection. Water samples were collected from underground sources, artesian wells, the municipal water supply network, and the Bug Estuary.
