Aerobic desulfurization of biogas by acidic biotrickling ...

Biotrickling filters for biogas ,desulfurization, still must prove their stability and robustness in the long run under extreme conditions. Long-term ,desulfurization of, high loads of H2S under ,acidic, pH was studied in a lab-scale aerobic biotrickling filter packed with metallic Pall rings. Reference operating conditions at steady-state corresponded to an empty bed residence time (EBRT) of 130 s,...

Ca removal and Mg recovery from flue gas desulfurization ...

Selective removal of Ca and recovery of Mg by precipitation from ,flue gas desulfurization (FGD) wastewater, has been investigated. Thermodynamic analysis of four possible additives, Na 2 CO 3, Na 2 C 2 O 4, NaF and Na 2 SO 4, indicated that both carbonate and oxalate could potentially provide effective separation of Ca via precipitation from Mg in FGD ,wastewater,.

Chloride Ion Removal from the Wet Flue Gas Desulfurization ...

The ,desulfurization and denitrification wastewater, (DDW) from the wet flue gas treatment project is difficult to be treated and recycled because of high chloride ion (Cl − ) concentration. Cl − can cause equipment and piping corrosion. However, there is a lack of cost-effective treatment technologies for the removal of Cl from the DDW.

Flue Gas ,Desulfurization Wastewater, Treatment Primer Page 3 of 15 The other common reason for purging ,wastewater, is the buildup of chlorides, which are typically limited to 12,000 mg/l, based on the metallurgy used in the scrubbers. With corrosion-resistant metallurgy, chlorides up to 35,000 mg/l can be handled, thus reducing ,wastewater, production.
