How does Phoslock work?
When Phoslock is applied to a water body as a slurry, it moves down through the water column, up to 95% of the FRP is rapidly removed and adsorbed onto the surface, forming an insoluble complex within the clay structure. As the Phoslock settles on the sediment-water interface it forms a ~1 – 3 mm layer. This layer of Phoslock is capable of adsorbing the FRP from the sediment layer on its available binding sites. Once the FRP is bound to Phoslock, it is no longer bioavailabile for use by algae for assimilation and growth. The lack of nutrients in the water body has a direct impact on the proliferation of algae. Phoslock operates over a wide range of pH (~ 4 to 11) and binds with phosphate even under anoxic conditions.
