Velia – MPPE

Similar to the Osorb media, Veolia MPPE (Macro Porous Polymer
Extraction) technology will extract BTEX and other light /
dissolved hydrocarbons to low concentrations. The MPPE media
is a bead with a significant porous structure for oil adsorbance.
The MPPE also can be regenerated with steam as needed.

The MPPE will improve the toxicity of the produced water These waters can have high solids, strong acids, solid stabilized
