Phoslock Water Solutions Limited (PWS) manufacture and distribute a product, “Phoslock” that was invented and developed by Australia’s leading research organisation, ‘CSIRO’ over 10 years of research and development. Phoslock removes orthophosphate (also known as Filterable Reactive Phosphorus, FRP) from the water body and forms a diffuse layer on the top of the sediment that continues to react with the phosphate released from the sediment. Uptake is very quick and the resultant bond is permanent, meaning that the FRP is locked out of the system permanently.
