An industrial solution

Economical and easy to use!

The PTE ’s polishing process is based on the principle of aerobic biofiltration using a percolating filter bed. The system may include one or two serial polishing stages, depending on the amount of flow and the strength of the wastewater to be treated. The treated wastewater meets stringent performance criteria, particularly for ammonia-nitrogen.

Our polishing process is ideal for treating wastewater from landfills, composting facilities and other industrial sites that generate leachate.
