Abstract

The fluid-bed reactor for biological effluent treatment, using carrier particles for microorganisms, consists of a tank with a retention system for the carrier particles, gas supply units and a jet ejector arranged along the tank for the particle recycle. The propulsion nozzle of the jet ejector is fed with the effluent stream which is to be treated.
