biological purification by ultrafiltration flat sheet membranes– Ultragreen™

Biological purification by ultrafiltration flat sheet membranes - Ultragreen Cogolin  station
Ultragreen™ is a wastewater treatment process (residential and industrial) by ultrafiltration flat sheet membranes. With a huge compact size, it provides a clean effluent quality to answer the most demanding emissions standards or to be recovered for reuse.

Ultragreen™ combines both a biological treatment using activated sludge and a clarification by immersion of flat sheet membranes. Water to be purified enters into a reactor where it is put in contact with a purifying bacterial mass, before passing through the membranes.

A boosted elimination of suspended solids: Ultragreen™ functions according to the out / in principle of immersion filtration, in other words a filtration flow from exterior to interior.

Ultragreen™ is particularly easy to use and it operates mechanically consolidated membranes plates.

In order to guarantee a high quality water, even in the case of strong seasonal variations and beyond the highest standards, the use of membrane technique allows to have a better control over the separation between water and sludge. It ensures the protection of the natural habitat, local population and water resources.
