The Rlevance of Blanket Solids Concentration in Understanding The Performance of Floc Blanket CLarifiers in Water Treatment

摘要

Investigations involved a variety of pilot and operational floc blanket clarification plants. The performance characteristics of such plants, used in the treatment of potable water, were established, in particular their dependence on solids concentration in the blanket. The blanket flux is espcially useful in characterising clarifier performance because its value passes through a maximum and hence identifies a unique condition. Mathematical models were derived to simulate actual clarifier behaviour and help show why blanket concentration and its ocntrol are improtant in achieving acceptable clarifier performance.
