Plasma Electrocoagulation (PEC)
- New advanced water treatment technology
PEC – Plasma ElectroCoagulation
- Combines traditional ElectroCoagulation (EC) with advanced Plasma technology
- More efficient than EC
- Cost-effective, reliable alternative or compliment to traditional chemical addition technologies
- High runtime, consistent performance and a small footprint (e.g. less space, higher water recovery)
- A leap forward in water treatment technologies
A Leap in Water Treatment Technology
Encotech combines advanced, patented plasma technology with traditional electrocoagulation revolutionizing water filtration methods and technology.

The Technology Behind Plasma EC
- EC Reactions plus highly active species generated with plasma
- Encotech developed technology to control plasma generation in conjunction with EC
- Saturable reactor – power supply
- Existing transformer technology, modified
- Reliable
- Automatically limits current output
- Insulator on electrodes
- Focuses power density to generate plasma at low power and voltage
- Automatically retracts as electrodes are consumed
- Integrated system according to Encotech’s patent-pending cross-flow filtration design
- Plasma effluent is filterable
Plasma EC – In Action
