What is Phoslock?

Phoslock was developed in Australia by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) to remove phosphates from water. The active element in Phoslock is lanthanum (a rare-earth element) which has a strong affinity to bind with phosphate. 

There is a small island in the middle of a lake surrounded by grass.

Environmental Certifications

Phoslock is safe for use in drinking water. See our environmental certifications here.

Application Methods

A combination of various mixing systems and vessel platforms are used in the application of Phoslock. 

Gaining an understanding of a water body at the early stage of a project will help us determine the best application method.
