Regenerable Adsorber Polymers
After a waste water treatment plant tensioactives concentrations are near or above law limits is normal practice to install a granular active carbon filter.
This solution often reveals some limits because the G.A.C. has a limited capacity and, due to it’s cost, seldom exchange of the G.A.C. bed is done with the required frequency.
Active Carbon also has a low affinity with amphoteric and non ionic tensides so it tends to release them by preferencially adsorbing anion tensioactives.
A new materials family denominated “Superadsorbers” has been syntetized.
The property of these materials are at the border between those of natural active Carbon and those of ion exchange resins.
Their porosity is extremely high, in the order of 1000 m2 for 1 gram of dry product.
Their belonging is similar to that of active Carbon but, due to their structure, it is possible to chemically regenerate them with acids and bases.
For this reason their use is much more economically interesting than that of G.A.C. because it is sufficient to chemically regenerate them instead of substituting the filter filling.
Organic matter removed from the treated water is then concentrated in a small volume that can be economically treated with Fenton’s reaction chemically destroying tensioactives.
