VWS MPP Systems a company of Veolia Water Solutions & Technologies is a business unit specialized in developing, marketing, manufacturing and servicing water purification systems based on Macro Porous Polymers (MPP). The Macro Porous Polymer Extraction (MPPE) system is a highly effective, fully automated, remote controlled and guaranteed technology for removing hydrocarbons from water by means of extraction in an MPP bed.
MPPE systems are used for:
- Process water
- Offshore produced water
- Groundwater
- Waste water
MPPE systems remove dissolved and dispersed hydrocarbons with efficiencies of 99.9999%, down to below ppb level, or as specified. This applies to different types of hydrocarbons, e.g.:
- Aliphatic
- Aromatic
- Polyaromatic
- Halogenated, e.g. chlorinated, bromated
The MPPE Process Description
In the MPPE process, hydrocarbon-contaminated water is passed through a column packed with MPPE particles. The particles are porous polymer beads, which contain a specific extraction liquid. The immobilized extraction liquid removes the hydrocarbons from the water. Only the hydrocarbons, which have a high affinity for the extraction liquid, are removed. The purified water can either be reused or discharged. Periodical in situ regeneration of the extraction liquid is accomplished by stripping the hydrocarbons with low-pressure steam. The stripped hydrocarbons are condensed and then separated from the water phase by gravity. The almost 100% pure hydrocarbon phase is recovered, removed from the system and ready for use/reuse or disposal. The condensed aqueous phase is recycled within the system. The application of two columns allow continuous operation with simultaneous extraction and regeneration. A typical cycle is one hour of extraction and one hour of regeneration.
