Who we are

We are global leaders in the treatment and remediation of freshwaters, dedicated to restoring healthy aquatic ecosystems through innovative geo-engineering. Our mission is to improve water quality worldwide by providing multifaceted solutions for water managers, governments, and industries. We specialise in addressing the root cause of water degradation, excess phosphorus, to reverse the symptoms of eutrophication, such as harmful algal blooms.

Our core technology, Phoslock®, is a proprietary lanthanum-modified bentonite (LMB) clay originally developed by Australia's national science agency, CSIRO. Unlike traditional chemical treatments, Phoslock® works by permanently binding free reactive phosphorus in both the water column and the lakebed sediments, forming the stable and biologically inert mineral Rhabdophane. This "locking" process prevents nutrients from being re-released into the water, even under varying pH or oxygen levels, providing a long-term remedy that is safe for aquatic life and human contact.

Beyond our flagship product, we offer a comprehensive range of technical and engineering services. From initial site assessment and water quality analysis to tailored dose design and professional application, our international community of scientists ensures every project is backed by rigorous scientific validation.

With over 300 successful applications across more than 20 countries, we are committed to creating sustainable, clean waterways for the communities and environments that rely on them.
