Fluidized Beds Fluidized beds are reactors in which small particles (with average size below 0.1 mm) are fluidized by the reactant gases or liquids. When the linear velocity is above the minimum required for fluidization, a dense fluidized bed is obtained. As the superficial velocity increases, the bed expands and becomes increasingly dilute. At a high enough linear velocity, the smallest particles entrain from the bed and have to be separated from the exhaust gases and recycled.

Fluidized beds Fluidization of the bed can result in enhanced heat and mass transfer performance. Unfortunately, many fluidized bed designs tend to be voluminous, which reduces overall storage efficiency.

Water often is treated in simple vessels known as batch reactors, which hold from a few hundred to many thousands of liters. Nutrients, microorganism, or both may be added to promote degradation of particular contaminants. Another variation on reactors designed for treatment of water is the fluidized bed. Fluidized beds usually contain biomass immobilized on or within carriers (e.g., polysaccharide-based beads, plastic saddles, sand particles, etc.). These carrier matrixes are circulated...
