Phoslock

Phoslock^® is a proprietary and unique water treatment product, representing the gold standard in phosphate management technology - permanently binding excess phosphorus in the water column and enabling it to settle in an environmentally benign state, eliminating the root cause of algae blooms and water quality issues.

Phoslock works by utilising the ability of lanthanum to react with phosphate. Removal of phosphate by lanthanum is highly efficient and has a molar ratio of 1:1 which means that one ion of lanthanum will bind with one ion of phosphate. This binding forms the mineral Rhabdophane (an insoluble and biologically inert compound) which strips phosphate from the water.
