*Humic Substances in Remediation

Traditional Remediation

Humic Substances

Bioremediation

*Humic Properties

Humic substances have the greatest beneficial effects on soil properties, including support for microorganisms, improved aeration and an increased water and nutrient holding capacity.

Humic substances are naturally occurring compounds found in the most fertile of soils. The characteristic dark color of soils can be attributed to these substances.

*Our Technology

We have developed a revolutionary process that allows us to isolate specifically targeted fractions of humic substances. Each fraction has unique properties and abilities for precise roles in remediation.

**Patent CA No. 2570565; US No.7896944 – Method for Extracting Fulvic Acid Molecules

*The Fractions

Humin – High Molecular Weight Humic

Substances

Humic Acid – Medium Molecular

Weight Humic Substances

Light Humics – Low Molecular Weight

Humic Substances comprise the most

bioactive fraction and includes the

more commonly known humic

compound fulvic acid (FA)Humic Substances

*Our Materials

Forward-Thinking &

Environmentally Responsible

CellXCell (CXC) is comprised of light humics. It is produced as a liquid concentrate.

Microhumate consists of humic acid and trace amounts of light humics. Like our CXC, it is produced as a liquid.

Terrahume is composed of the humin fraction. It is produced as a powder.

All of our products are nonhazardous and are produced without the use of chemical extractants.

*Benefits in Remediation

CXC

• Binds to and mobilizes heavy metals and radionuclides for removal

• Increases the growth and metabolic functions of aerobic and anaerobic microorganisms

• Makes poorly soluble hydrocarbons more available to microbes

Microhuma

te

• Assists in nutrient uptake• Sequesters heavy metals and

radionuclides in deep locations• Weaker bio-stimulant properties

Terrahum

e

• Increased aeration & water holding capacity

• Sorbs contaminants and sequesters them from the surrounding soil to reduce solution concentrations

Compounds VOCs Odors

*Example Humics Treatment (1)

• Soil is leached using EDTA to bind to heavy metals for removal.

Traditional Method

• Bind to heavy metals and are not subject to biodegradation.

Role of Humics • Replace EDTA with

CXC and leach as normal.

Alternative

• No losses due to biodegradation; more efficient throughput for collection.

Results

LEACHING OF HEAVY METALS

*Example Humics Treatment (2)

• Surfactants are pumped into the soil to solubilize diesel fuels.

Traditional Method

• Increase diesel solubility & stimulate microbial decomposition.

Role of Humics • Replace

surfactants with CXC and pump into the soil.

Alternative

• Buffers fuel solution levels & provides long-term stimulation of microbes.

Results

IN-SITU BIOREMEDIATION OF HYDROCARBONS

*Example Humics Treatment (3)

• VOCs are either flamed off or captured using activated carbon.

Traditional Method

SOIL VAPOR EXTRACTION OF VOCS

*Example Humics Treatment (4)

• Excavate and stockpile cesium contaminated soil.

Traditional Method

• Complex cesium ions; cesium is desorbed from the soil into a water solution.

Role of Humics • In-situ soil

remediation; capture of cesium onto absorbent material.

Alternative

• Economical and practical removal of cesium radionuclides.

Results

REMOVAL OF CESIUM RADIONUCLIDES FROM SOIL

*Consultation Process

1.Review existing data from the zone of contamination

2.Visit the site for a general assessment

3.Perform additional testing for unknown but significant factors

4.Analyze test results

5.Ascertain engineering and land management requirements

6.Develop general recommendations and design treatment trains based on agreed upon goals

7.Select and delineate target areas for the installation of treatment designs

8.Monitor feedback and results from treatments and recommend adjustments as necessary
