Inside the system, the mixture of ultrapure water, slurry or other chemical materials passes through several filtration stages, separating the original raw materials and allowing them to be reused. The patented backflush process of the ultrafiltration modules has led to a drastic increase in the service life of the high-cost filter elements. As a result, the filters no longer have to be replaced after a few days. They last for more than a year, thus increasing the cost efficiency of the system even further.
For the first time, it has become possible to separate wastewater efficiently and economically into its main constituents. Up to 85 % of the slurry and 90 % of the ultrapure water can be recycled to the process. Recovered precious rare earths can be reused.
