these inorganic flocculants, PACs are widely used in drink-ing water and wastewater treatment. However, they are very sensitive to pH, inefficient at low temperatures, limited to only a few disperse systems, and large amounts are required for effective flocculation, thus generating a large volume of sludge which is challenging in wastewater treat-

In wastewater treatment, they enable up to 90% reduction in suspended solids and organic loads. All waters contain suspended particles. The smallest particles (colloids) are stabilised by the action of physical forces (static electricity) on the particles themselves and, because they all have a negative charge when suspended in water, they ...
