Oxygen Sparge Units

H2O Engineering's oxygen sparge technology delivers a high concentration of oxygen gas directly to the contaminated subsurface. Oxygen is released in controlled time duration sequences via in-situ oxidation points. This feature can be programmed and recorded by the logic controller.

H2O Engineering's oxygen sparge units are completely self-contained and are available in trailer and cabinet enclosures. While we have designed our standard units to handle most field conditions, we also offer custom systems to meet extraordinary site demands. Our systems are successfully remediating petroleum hydrocarbons such as TPHg, TPHd, BTEX and MTBE in both groundwater and soil applications.

H2O Engineering's control panels are UL 508 certified . We strive to manufacture the most reliable, robust equipment in the remediation industry.
