DiaPureTM filter material combined with sediment removal through a lamella filter

undefined

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.
