Phoslock

Phoslock fonctionne en utilisant la capacité du lanthane à réagir avec le phosphate. L'élimination du phosphate par le lanthane est très efficace et a un rapport molaire de 1:1, ce qui signifie qu'un ion de lanthane se lie à un ion de phosphate. Cette liaison forme le minéral Rhabdophane (un composé insoluble et biologiquement inerte) qui élimine le phosphate de l'eau.

Phoslock® is a proprietary and unique water treatment product that permanently binds excess phosphorus in the water column and enables it to settle in an environmentally benign state. It was developed in the 1990s by the Australian national science agency CSIRO and consists of lanthanum-modified bentonite.

• Phoslock utilizes the ability of lanthanum to react with potentially releasable phosphate primarily from the sediment but will also react with phosphate in the water column during application.
• Phoslock binds available phosphate to form the naturally occurring, non-toxic, inert mineral Rhabdophane.
• Scientific evidence shows that Phoslock does not pose any risk to freshwater biota or have any human health related risks.
