#### Challenge

- Waste water form Coating/Printing Ink/Resin Production like alkyds, acrylic and polyester resins
- Frequent fouling of exisiting steamstripper from heat polymerization
- Replace existing steamstripper



 

 

 



####  

#### Performance

  
**MPPE removes:**

- Aromatics, BTEX 200,000 -> 20 ppb

**MPPE Unit capacity 5m3/h (30g pm)**

  
Process wastewater discharge to Louisville’s Metropolitan Sewer District is regulated under the Organic Chemical, Polymer, Synthetic Fiber (OSPSF) category standards of the U.S. EPA.

  
**Vs. steamstripper:**

- Lower costs (50%)
- Less space (1/3)
- Higher capacity (4x)
- Trouble free



 

 

 



 

 

#### Resin production waste water

- Akzo Nobel (Coatings)
- TOTAL – Cook Resins (Houston)
- DuPont (Printing Inks)
- Operational since 1998



 

 

 

 

 

 





#### The MPPE process

  
*MPPE stands for Macro Porous Polymer Extraction. Polymer beads contain a specific immobilized extraction liquid. Hydrocarbon contaminated water is passed through a column packed with MPPE particles. The hydrocarbons are extracted from the water at any designed efficiency up to 99.999%. The MPPE particles can simply be regenerated by heating with steam. The removed hydrocarbons are recovered as an almost 100% pure product. No other waste stream is created. No chemicals requires, no off gasses produced.*
