Abstract

A method of floatation separation treatment of a raw water, which comprises a step of supplying floating particles to the raw water, a step of forming aggregates containing floating particles comprised of floating particles and suspended materials and/or agglomerates from the raw water adhered to the floating particles, and a step of allowing the aggregates containing floating particles to float in the raw water, to separate the aggregates containing floating particles from the raw water; and a system for floatation separation treatment of a raw water for practicing the method. The method provides a rapid solid-liquid separation technique which allows the separation of suspended materials and/or agglomerates from a raw water in a very short time.
