C-SPARGER® “GENESIS OF OZONE SPARGING”
 It all started with the belief that ozone, one of nature’s most powerful oxidants, could be deployed as small gaseous bubbles throughout the pores of a contaminated soil matrix to immediately react with and destroy volatile organic contaminants. From that belief, a new remediation method was born.
The ozone sparging process (C-Sparge™) employs nano- to micro-sized bubbles of air encapsulated ozone created by injecting an air-ozone mixture through invisible pores in KTI’s Spargepoints®. Pressure-pulsing the microbubbles of air/ozone through soil and groundwater yields rapid clean-up of a host of contaminants by means of in-situ chemical reactions that leave only water and beneficial oxygen as byproducts: O3 + 2H+ + e- ? O2 + 2H2O
Pulsing the air/ozone mixture enhances the process scrubbing capacity, gently pushes the bubbles through soil capillary pores, and by providing appropriately-sized bubbles, eliminates channeling.
In-situ ozone sparging treats a wide variety of contaminants: Saturated hydrocarbons such as petroleum hydrocarbons (alkanes); MTBE; 1,4 dioxane; chlorinated ethanes (1,1,1 TCA, DCA); and unsaturated hydrocarbons such as chlorinated ethenes (PCE, TCE, DCE, VC); BTEX; methylbenzenes; chlorinated phenols (PCP, DCP, etc.); energetic (RDX, HMX); polycyclic aromatic hydrocargons (PAH); PCBs; pesticides such as Heptachlor, Aldrin, Dieldrin.
Advantages
- Wide variety of treatable contaminants
- Low Capital equipment/operating costs
- Requires standard 120 VAC household current
- Minimal installation site disturbance; low site profile
- In-situ rapid destruction of targeted compounds
- Clean reaction; no hazardous byproducts
- No vapor control necessary
- Pulsed microbubble oxidant injection ensures maximum contaminant contact
