Yutan Reservoir

In late 2019, Phoslock China met with local officials after Phoslock was highly recommended as a suitable control measure for Yutan Reservoir. Shortly after this, due to COVID-19, progress with this project was temporarily put on hold. It was not until March 2020 that a detailed site study and lab jar testing was undertaken, conducted in cooperation with the local water engineering company contracting for project delivery. The Phoslock Europe team assisted with a review of the site information and data, offering advice on a preferred Phoslock treatment strategy.

The initial application of Phoslock, as a large scale trial has proven successful. The second round of the Phoslock application (which will be up to approximately 300 tonnes) will be applied before December 2020.
