Wet Flue Gas Desulphurization (FGD) Wastewater Treatment Using Membrane Distillation

The use of waste incineration with energy recovery is a matured waste-to-energy (WtE) technology. Waste can reduce the volume and mass municipal solid significantly. However, generation high volumes polluting flue gases one major drawbacks this Acidic are constituents in gas stream which deemed detrimental to environment. wet desulphurization (FGD) method widely employed clean acidic from streams, due its efficiency. A setback FGD technology production wastewater, must be treated before reuse or release into Treating wastewater presents challenges owing level contamination heavy metals other constituents. Membrane distillation (MD) offers several advantages regard, capture low-grade heat drive process. In study adopted for proposed plant located Ghana. Through flow analysis it was found that MD well matched treat 20 m3/h generated during operation. Thermal performance system assessed together two parametric studies. thermal efficiency, gained output ratio, specific consumption optimized simulated 64.9%, 2.34 966 kWh/m3, respectively, total demand 978.6 kW.
