In-situ and Ex-situ Remediation

IN-SITU GROUNDWATER AND SOIL REMEDIATION

Since 1997, Ozonology has been designing and fabricating turnkey systems for remediation of groundwater and soil. Working with a prospective client’s engineers, together we examine the requirements of a site and, drawing upon Ozonology’s experience in equipment design, we conceptualize a system that meets the specific requirements of that site. Ozonology then submits a drawing(s) of the envisioned system for review. Following approval of the design, a quotation with detailed itemization of the proposed equipment is submitted for consideration.

In-Situ Ozone/Air Sparging Systems

Mobile system in 48' trailer: First used at a Superfund site to remediate groundwater and soil VOCS (benzene, diethyl ether, isopropyl alcohol, phenol, toluene, TCE, PCE, DCE, among others), then moved to another site when monitored natural attenuation (MNA) was deemed to be adequate by EPA. A Five-Year Review stated "...the remedy was protective of human health and the environment."
Installed ozone capacity: 3 lbs/day using dry air feed.
Installed sparge wells: 60 wells divided into 10 groups, with PLC to sequentially pulse ozone/air flow of each group at 3 CFM per well.

A mobile remediation trailer is sized to meet the component space requirements of a system, and typically is 10'~24' in length.

Stationery system in 20' container
24 lbs/day ozone
30 sparge wells in six groups of five wells/group, 9 CFM ozone/air flow at each sparge well.
PLC controls pulsed sparging of ozone/air (groups sequentially cycle based on user programmed time duration)
COC - chlorinated solvent TCE

Stationery system in 20' container
24 lbs/day ozone
80 sparge wells in eight groups of ten wells/group, 2 CFM ozone/air flow at each sparge well.
PLC controls pulsed sparging of ozone/air (groups sequentially cycle based on user programmed time duration)
COC - diesel from truck fueling

SVE ~ In-Situ Soil Vapor Extraction Systems

Mobile SVE - 14' Trailer

Typical components of a SVE system:

Vapor extraction blower (Regenerative blower for low vacuum at lower flow rates, Rotary Claw blower for low to high vacuum at lower flow rates, or Rotary Lobe blower for low to medium vacuum at higher flow rates
Knockout tank/moisture separator
Positive displacement pump (transfers liquid from knockout tank under vacuum to a condensate receiver tank)
Particulate filter (for blower intake)
Silencer (for blower discharge noise)
Vacuum relief and air dilution valves
Temperature and vacuum gauges
Intake manifold for (x#) extraction wells
Monitoring and flow instrumentation
Ventilation, heat and A/C as required
Optional VFD for blower CFM flow control
Optional telemetry for system remote control and monitoring
