Liquid Fire

A revolutionary mobile technological development in the treatment of contaminated soil brought to you by Spill Tech - Responsible Environmental Management
What is Liquid Fire?
  • Liquid Fire represents an accelerated on-site method of remediating petroleum (and other) hydrocarbons in contaminated soils.
  • Based on the site specific sample results - our dedicated soil scientist reviews and designs a bespoke soil treatment process.
  • The system can treat petroleum hydrocarbons and more recalcitrant compounds such as chlorinated solvents, pesticides and  herbicides.
  • Turnaround time to reach target level compliant soils within as little as 2 days.
  • Liquid Fire system can treat up to 150 tons of contaminated soil per day.

Traditional Bio-Remediation
Liquid Fire
Time consuming (months) Fast and effective
Labour, equipment and space intensive Mobile unit with small footprint and minimal staff
Between 4 and 24 months remediation time Remediation within 48 hours from treatment
Continuous monitoring and maintenance of the site required No post treatment maintenance required
  Remediated soil available for backfill immediately after treatment
The Process

Liquid Fire involves a combination of physical and chemical treatment. Contaminated soil undergoes mechanical pre-treatment that removes rocks and cobbles from the soil, The mechanical preparation of the soil ensures that the soil is of a standard consistency required for the chemical treatment process. Following the mechanical treatment process, the soil is then put through the Liquid Fire unit where a proprietary blend of chemical agents are applied to the contaminated soil. The chemicals rapidly oxidize the contaminant rendering the soil rehabilitated.

  1. SOIL STOCKPILE
    • Laboratory analysis to identify contaminants (Petroleum, Solvents, Herbicides, Pesticides, Cyanide)
    • Identify soil type and moisture regime
  2. INTERPRETATION OF DATA AND DETERMINATION OF DOSAGES
  3. PHYSICAL PROCESSING
    • Remove rubble, boulders, cobbles and prepare for physio-chemical processing
  4. CHEMICAL PROCESSING
    • Site specific blend of chemicals added to soils to destroy contaminants
    • NOT bio-remediation: contaminants are mineralised to CO2 and H2O
  5. VALIDATION
    • Soil samples submitted for validation laboratory analysis and compared to accepted target limits
  6. RESTORATION
    • Replacement of soil, compaction and make good (if required by client)

Advantages of Liquid Fire
  • Rapid on site treatment (Results within 48 hours of treatment)
  • Hydrocarbons mineralised (destroyed) to basic constituents of CO2 and  H2O
  • Zero to negligible runoff water produced requiring catchment and treatment / disposal
  • Mobile and agile deployment of equipment to different locations
Actual Case Studies
Case Study #1

A quantity of 1 320 tons of soil was contaminated by an underground fuel storage tank leak at a service station forecourt. The soil was contaminated with diesel. The affected soil was excavated and stockpiled for treatment. Samples were lifted and analysed to determine the treatment recipe. Once treatment process was determined, the process took a total of 33 days to conclude. Upon completion of the treatment, samples were lifted for analysis to  confirm the effectiveness of the process. The process was proven to be successful and the treated soil was backfilled into the excavation following the verification sample analysis.

Sample Description
TOTAL "TPH Banded C10-C36" (mg/kg)

(Analysis performed at an independant accredited labratory)

Average Maximum
Values pre-treatment 19 050 24 000
Values after treatment** 54 69
   
** Post-treatment values complied with RSA DEA SSV1    
     
     
Case Study #2

A tanker rollover resulted in a large spillage of paraffin. 960 tons of the impacted soil was excavated and stockpiled for treatment. The process took 3 weeks due to the soil having a very high clay content. Upon completion, the analysis of the soil samples at an independant accredited labratory confirmed the effectiveness of the treatment process. The successfully treated soil was utilised as backfill.
