The effect of cation addition on the settling and dewatering properties of an industrial activated sludge
… sludge system improved sludge volume index (SVI), but produced high supernatant solids. Sodium addition resulted in weak flocs and a deterioration in sludge dewatering. Potassium addition also resulted in poor sludge dewatering but did not significantly affect floc stability. The addition of …
