DiaPureTM filter material combined with sediment removal through a lamella filter


DiaPure sorbent material works for phosphate sorption to the iron oxide coatings in the calcined diatomaceous earth.

The high internal porosity of the sorbent granules allow for intraparticle P sorption and storage, while the 2- 4 mm size of the granules allows for a high hydraulic conductivity of the DiaPure sorbent.


In the NuReDrain project DiaPure will be combined in a system that also consists of a lamella filter for sediment (and P) removal and a filter with crushed seashells as porous reactive filter for dissolved phosphorus.
