Incineration
Mit Water provides incineration systems for thermal destruction and volume reduction of sludge, concentrated brine and other hazardous organic waste streams from water and wastewater treatment processes. Incineration achieves near-complete destruction of organic matter and produces a sterile, inert ash residue suitable for landfill disposal.
Working Principle
Dewatered sludge or concentrated liquid waste is fed into a high-temperature combustion chamber where organic material is oxidised at temperatures of 850-1,100 °C with excess air. The combustion process converts organic carbon to CO2, hydrogen to H2O, and nitrogen to N2. Inorganic constituents remain as bottom ash or fly ash. The hot flue gas passes through waste heat recovery, air pollution control and emission monitoring before release.
System Configuration
A complete incineration system includes a feed handling system, combustion chamber (rotary kiln, fluidised bed, or multiple hearth), auxiliary fuel burner, waste heat boiler, flue gas treatment (bag filter, wet scrubber, activated carbon injection), induced draft fan, stack, and a PLC-based control system with continuous emission monitoring (CEMS).
Incineration is used for waste streams requiring thermal destruction:
- Municipal wastewater treatment plant sludge
- Industrial hazardous sludge from chemical and pharmaceutical plants
- Reverse osmosis concentrate and evaporation residue
- Oily sludge from petroleum refining
- Spent activated carbon thermal regeneration
