Ferric Chloride
Vendor: Kemira Water Solutions

The primary method for removing phosphorus at the WRRF is by adding iron salts (ferric chloride) to the wastewater stream which reacts with the phosphorus and precipitates out of the flow stream. Phosphorus removal is desired to reduce the impact of higher nutrient loadings (eutrophication) on the receiving waters. Eutrophication is a cause of the seasonal cyanobacterial blooms (harmful algae blooms) in the receiving water body.
JUSTIFICATION
The WRRF is required to remove phosphorus to meet effluent limits required in the WRRF's NPDES permit. Ferric chloride is an essential chemical necessary for treatment of phosphorus at the WRRF to ensure compliance with its permit.
