Water Purification Systems Based On Macro Porous Polymers (MPP)
About Us
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.

MPP Benefits
1 Very High Separation Performance: Reduction factor. 1,000,000 times = 99.9999% removal if required. 2 Cost Competitive: Cost competitiveness proven compared with air stripping and activated carbon, steam stripping and biotreatment systems. 3 Low Energy Consumption: Low energy input to release hydrocarbons from MPPE particles (in situ regeneration) Energy consumption up to 50 times lower than steam stripping 4 Robust, No Fouling: Anaerobic operation at ambient temperature. No interference from dissolved iron, heavy metals, surfactants, salt and polar compounds, and no scaling No biological fouling because of periodic in situ regeneration by steam 5 Reliable and Easy Operation: Fully automated Remote control using laptop and mobile telephone 6 Flexible Operation: Once installed, the unit can treat higher and lower flows and concentrations. For example, if the concentration is 50% higher, effluent requirements can still be maintained with only a 10% lower flow. At lower feed concentrations, higher flows can be treated while still meeting the effluent demand 7 Compact Equipment: Compared to existing technologies, the unit is compact with a small footprint. 8 Ideal for Upstream Process Integration: Because it is compact, robust, reliable, fully automated, remote controlled, easy to operate and flexible, it is ideal for process integrated applications. 9 Performance Guarantee during Operational Life: The material performance is guaranteed during the operational life of the unit irrespective of the number changes of the MPPE material 10 Environmental Benefits: Practically pure separated hydrocarbons for use/reuse Low waste of polymer Long lifetime Reuse of spent material Low energy consumption Low noise No addition of chemicals No emission to air No (chemical) iron hydroxide waste

Industrial Process and Wastewater Treatment
Process water streams are treated upstream and end of pipe for possible reuse of water in the production process, or for discharge to surface water or to site/community biological wastewater treatment. Typical Challenges MPPE Can Meet: High influent concentrations High reduction factors Varying concentrations and compositions Varying flows Varying/wide pH range Presence of salts, surfactants, heavy metals, alcohols, monomer residues, pre-polymers etc. Extra Benefits Include: Small footprint Upstream integrated operation with remote control Scope for adding other process- and groundwater streams, for treatment in one unit Reduced sludge formation in biotreatment Modular set up for large flows (thousands of m3/hr) Removal of total spectrum of non-polar and polar organics proven in practice: Non-polar toxic non-biodegradable compounds and polar biodegradable compounds are removed by MPPE in series with biotreatment. Full turnkey contracting is possible, as is partnering with local biotreatment suppliers. Industries Natural gas production/treatment - Aromatics, polyaromatics, aliphatics (3000 ppm and above) LNG terminals/gas to liquid plants - Aromatics, polyaromatics, aliphatics Underground gas storage - THT (tetrahydrothiophene), aromatics Water, oil, gas/condensate produced onshore - Aromatics, polyaromatics, aliphatics Chemical, specialty chemical and pharmaceutical raw material producers - Broad range of aromatics, aliphatics and halogenated (chlorinated/bromated) hydrocarbons Chemicals/oil storage distribution industry:- Tank cleaning process water- Aromatics, aliphatics and halogenated hydrocarbons Resin production - Solvents/aromatics removal from process streams containing monomer residues Electronics Industry - Solvents removal (toluene) e.g. television screen factories Rayon/viscose industry - Carbon disulphide (CS2), aromatics, aliphatics

Offshore Produced Water Treatment
Regulations for offshore produced water are becoming more and more stringent. New technologies are required for this challenging segment in order to meet future emission standards that are being set by international organizations, (for example OSPAR*) for the Northeast Atlantic.

Groundwater Remediation
Aromatic, polyaromatic and halogenated hydrocarbons in ground water can be found in lower concentrations dissolved in water diffused over the area, or concentrated as DNAPLs (dense non-aqueous-phase liquids) or LNAPLs (light non-aqueous-phase liquids) creating an enduring source of contaminant supply to the water phase. MPPE benefits for meeting challenges in this segment are: Ideal for handling a broad range of compositions Able to cope with unexpected higher influent compositions at no additional costs No iron removal necessary (anaerobic process) Robust, can withstand e.g. salts, humic acids, surfactants, heavy metals, dissolved/suspended solids, high/low pH etc. No sludge formation (as with iron removal and biotreatment) Scope for combination with other ground- and process water streams in one unit DNAPL and LNAPL removal by solvent or surfactant enhanced aquifer remediation (SEAR) Surfactant or alcohol injection enhances the dissolution of chlorinated hydrocarbons, PAHs, DNAPLs and LNAPLs in water from a few ppm to 10,000 – 50,000 ppm Organics recovered in two weeks equaled eight years of normal pump and treat MPPE proven as the ideal separation technology for these extremely high concentrations in surfactant/alcohol water mixtures Surfactant/solvent consumption savings as MPPE enables recirculation and recovery
