The Fluid Bed Municipal Refuse/Sludge Incinerator System is a proven and low cost process using refuse as fuel to incinerate water sludge with no auxiliary fuel required. It can be used for either disposal of sludge alone or it can be used for co-disposal of sludge and municipal solid waste. After heat recovery for steam/power production, custom designed flue gas treatment systems are used to remove any air pollutants. In other applications, up to 97% of sulfur fed to an Enders Fluid Bed Incinerator can be adsorbed by lime when lime is added to the bed as in the case of burning high sulfur coal for steam production.

Many installations, using fluid bed technology are operating worldwide in chemical plants, pulp mills and municipal sewage treatment plants for disposal of liquid and solid waste; most with heat recovery or power generation. For disposal of municipal solid waste, combustibles in the waste are first separated and shredded as required for feeding the reactor. Non-combustables are either recycled or land filled.

Flue gas treatment can be as simple as a venturi scrubber/ secondary packed scrubber system, or a more complicated system containing lime/activated carbon reactor, bag collector, lime feed system, powdered activated carbon feed system and flue gas reheat exchanger. The former for particulate removal; the latter for removal of particulate, hydrochloric acid, sulfur dioxide, polychloric acid, polychlorinated dibenzo-P-dioxin, heavy metals and stack plume.
