Sand Filtration

Aquazur V is a descending current open sand filter which retains suspended particulate matter in raw water, thanks to a thick layer of sand.

The homogeneity of the sand increases the filter run time, while the thickness enables filtration at high speeds and the high water haed (1.20m) prevents degasification.

In a tertiary treatment line, Aquazur V is well adapted for suspended solids (SS) and phosphorous removal. At last this sand filtration process will enhance any disinfection process downstream such as UV radiation or chlorination.
