PulseOx® Overview

nnnn

Up to 1 Billion Times Faster. No Extra Charge.

nnnn

APTwater's PulseOx® process is an in-situ chemical oxidation (ISCO) technology for

nnnn

the remediation of contaminated soil and groundwater. PulseOx systems offer 35-50%

nnnn

more powerful chemical oxidation, and up to 1-billion times faster reaction kinetics than

nnnn

conventional air-sparge or ozone-sparge remediation systems. PulseOx systems deliver

nnnn

greater value through faster cleanup and closure of environmental remediation sites.

nnnn

The PulseOx system is based on patented ozone + hydrogen peroxide sparge technology

nnnn

that produces Advanced Oxidation Process (AOP) chemistry directly in the subsurface. This

nnnn

powerful hydroxyl radical oxidation chemistry rapidly oxidizes a wide range of groundwater

nnnn

contaminants. One powerful benefit of the PulseOx AOP reaction is a tremendous increase in

nnnn

groundwater dissolved oxygen (DO) content which promotes natural attenuation across the

nnnn

site. The aggressive injection process enables rapid clean-up of highly contaminated "hot-

nnnn

spots" or the effective development of contaminant barriers or "sparge curtains."

nnnn

PulseOx systems are available in a range of standardized sizes to suit a wide range of

nnnn

application needs. The self-contained and fully-automated systems allow for rapid

nnnn

deployment and easy operation.

nnnn

The PulseOx system operates by injecting a sequence of pressurized 'pulses' of ozone,

nnnn

hydrogen peroxide, oxygen, and air directly into the subsurface. The injection sequence,

nnnn

timing, and proportions can be fully customized to assure that all chemicals and hydroxyl

nnnn

radicals are thoroughly distributed in the zone of contamination.

nnnn

HIGH VALUE APPLICATIONS INCLUDE:

nnnn

Petroleum Hydrocarbons (BTEX,

nnnn

TPHg, Diesel, Aviation Fuel, etc.)

nnnn

Chlorinated Solvents (PCE, TC E, DCE,

nnnn

VC, and most intermediaries)

nnnn

Solvent Stabilizers (1,4-dioxane)

nnnn

Fuel Oxygenates and Byproducts

nnnn

(MTBE, TBA, etc.)

nnnn

PAHs (naphthalene and other aromatic

nnnn

compounds)

nnnn

Creosols/ Phenols (creosote and

nnnn

many phenolic compounds)

nnnn

NAPL destruction in source areas or

nnnn

vadose zone soils

nnnn

Other Organics (naturally occurring

nnnn

organic materials, tannins, etc.)

nnnn

The entire PulseOx process is fully-automated. Injection intervals and volumes are set

nnnn

based on patented process chemistry that is customized to the type of contamination

nnnn

and actual site conditions. All systems are provided with full instrumentation for remote

nnnn

monitoring of all critical process parameters and to assure the highest level of safety. Once

nnnn

started, the system can provide fully-unattended remediation to increase productivity and

nnnn

significantly reduce treatment cost.
