COST EFFECTIVE, LOW MAINTENANCE SYSTEM TO ACHIEVE TOTAL PHOSPHORUS

Phosphorus is generally the limiting nutrient that controls eutrophication and water quality in freshwater bodies and in some estuarine areas. Coastal freshwater ponds in particular have phosphorus management challenges as the soils are typically sandy and have very limited, and reversible as the USGS has determined, capacity for phosphorus removal. Phosphorus contributions from on-site wastewater management systems is the cause of coastal pond accelerated eutrophication in many areas. There are limited small flow phosphorus treatment technologies available.Phosphorus removal can be achieved by:SorptionMineralization with iron, aluminum or calciumPrecipitation with ferric chloride or aluminumBiological Nutrient RemovalOf these techniques, only sorption, mineralization and precipitation are considered viable for small to medium (individual to cluster size to
