Technology Overview

XOG EN® Wastewater Treatment Systems combines:6 Electro-oxidation

6 Electro-flotation

6 Electro-coagulation

6 Disinfection into one unit process.

Xogen’s patented technology is proven effective for thewastewater treatment for organics, BOD, COD, Ecoli,ammonia, cyanides, nitrates, metals, oil and grease andsuspended solids reduction.

Treatment

Treatment depends on current (amps), surface area ofelectrode (anode) vs Volume of water (Litres or m3)

Electrode coating

ö Balance between efficiency and effective removal

o Treatment for most compounds is concentration dependantexcept for COD

Key Benefits of the Xogen System

o Modular: Multiple small modules can be either stacked or cascaded to easily buildsmall (5 m3 per day) up to very large (40,000 m3 per day) installations

0 Minimal By-Products: Process is odorless; up to 50% less solids then biologicaltreatment and requires minimal addition of reagents

o Robust Process: ON/OFF, temperature stable, long lasting electrodes

o Cost Effective: OPEX approximately $1.84/m3; similar to CAS and less than MBR

0 Hygenic Outflow: Electrochemical/oxidation lowers bacterial count and disinfectslike UV, chlorination, and ozonation

0 Process Control: Can respond to changes in contamination loading

0 Fast Processing: Single pass operation, retention time in minutes (versus 8 — 12hours in biological systems)

0 Smaller Footprint: Plants are up to 75% smaller than incumbent technologies

0 Rapid Start-up: Process can be brought into operation in minutes allowing mobileor on-demand applications
