Enrichment of inorganic trace pollutants in re-circulated

Sep 01, 2011· Research highlights Inorganic trace pollutants are enriched in FGD waters at two power plants. Mass balances support the enrichment as result of water re-circulation. Use of additives, F − and SO 4 2− complexes, S/F and S/Cl promote the enrichment. Water enrichment may reduce the gaseous retention efficiencies by FGD. Preventive/corrective measures should be studied and applied.
