Phoslock

Phoslock werkt door gebruik te maken van het vermogen van lanthaan om met fosfaat te reageren. Verwijdering van fosfaat door lanthaan is zeer efficiënt en heeft een molaire verhouding van 1:1, wat betekent dat één lanthaan-ion zal binden met één fosfaat-ion. Deze binding vormt het mineraal Rhabdofaan (een onoplosbare en biologisch inerte verbinding) die fosfaat uit het water haalt.

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.
