Phosphorus is a nutrient that is essential to farming. Yet runoff of phosphorus into waterways can contribute to toxic algae blooms. It''s why environmental regulations require wastewater treatment operators to remove phosphorus from effluent. The existing Liverpool system removed phosphorus in an unrecoverable form.

Biological Nutrient Removal (BNR) is a process used for nitrogen and phosphorus removal from wastewater before it is discharged into surface or ground water. The rising concentration of harmful nutrient compounds – specifically nitrogen and phosphorus – in municipal wastewater treatment plant discharge causes cultural eutrophication (nutrient enrichment due to human activities) in surface waters.

Phosphorus is vital for food production and animal feed. We waste a lot of the valuable P because of insufficient wastewater treatment and poor nutrient recycling. The dominating process for the removal of phosphorus is chemical precipitation. With chemically precipitated sludge, effective nutrient recycling is also possible, making phosphorus available to plants and crops.
