Bioremediation Services

Procon offers specialised cleaning, including confined space cleaning, high-pressure cleaning and tank cleaning.

Under carefully controlled conditions, Procon provides cost-effective bioremediation solutions to remove hydrocarbons from contaminated surfaces and sub-surfaces, i.e. soil, water, ballast stone, paving etc.

All soil contains microorganisms, and when hydrocarbon spills occur in soil, the microorganisms, as well as the soil nutrients are killed.
Procon Environmental Technologies has investigated the best technology available to meet your requirements, and with this in mind, we intend to provide you with solutions, including:

  • Bioremediation projects and oil spill clean-ups on land and water
  • Spill kits and environmental control products

Bioremediation refers to any method that uses microbes to recycle organic materials and sequester inorganic ions. Because the primary responsibility of microbes is to recycle organic material, they must be present in sufficient quantities and diversity in order to do this. Under carefully controlled conditions, bioremediation can be a practical and cost-effective method in removing hydrocarbons from contaminated surfaces and sub-surfaces.

Bio-augmentation is the addition of naturally occurring microbes to sites, while bio-stimulation is the modification of the site to enhance the growth of indigenous microbes that are already present. Procon specialises in bio-augmentation.

BASICS AND ESSENTIAL REQUIREMENTS

Under optimal conditions, a single microbe can divide every 20 to 30 minutes, and can live a long as optimal conditions exist. Once these conditions are no longer present, the microbes will die off, be eaten by other microorganisms, or become dormant.

Conditions:

Need a food source to be present and available.

Takes the place at the oil or water interface.

Activity is limited by oxygen (at a residual level of 1 ppm or more).

Requires inorganic nitrogen, phosphorus and potassium nutrients.

One microbe can utilise one cell with 8 hydrocarbon per hour.

The water used to activate microbes can be fresh or salt water.

It’s a enzymatic process, wherein various enzymes effectively “cut up” the molecule.

Is directly related to the number of microbes present.

It is transformation instead of transportation.

The greater the surface, the faster the microbes work.

Must exceed 1 million microbes per gram of soil for enhanced bioremediation to proceed.

Other conditions must be taken into account, such as pH, temperature, salinity, type of contaminant, etc.

Daily, thousands of tons of oil, gas and hazardous materials are reportedly spilled into our oceans, land and air environments. Spill response includes the actions taken to reduce the harmful effect of a spilled product on its receiving environment. Regardless of whether the spill is the result of human error, mechanical failure or environmental conditions, the clean up needs to be an immediate priority for the organisation responsible for the incident.

Bioremediation method of soil:

  1. The soil is dug up until the lowest level of contamination is removed. Samples of the soil are taken before work commences.
  2. All clods are broken up to ensure even coverage of the microbial products.
  3. Pro Soil Treat is applied to remove the excess hydrocarbon contamination from the soil.
  4. Terrazyme is applied and mixed through the soil to ensure all contamination is treated. The microbes digest the hydrocarbons and release harmless byproducts.
  5. Nutrients are added to the soil to assist the microbes.
  6. The area is sprayed with a mixture of water and ProSolve (our environmentally friendly degreaser) to activate the microbes. The ProSolve also assists in loosening the hydrocarbons from the soil particles.
  7. Once the remedial process is complete (2 to 4 weeks after treatment, depending on contamination level), the supervisor will take samples again, and have these sent for analysis.
  8. A full job report will be submitted upon completion of the project.

Spill kits and environmental control products can also be procured from Procon Environmental Technologies. Contact us today to find your best environmental solution.

ProSolve 25 l

Environmentally friendly, non-emulsifying degreaser.

Directions for Use
ProSolve can be used to clean a wide variety of items. It can be diluted for household use, and can be used undiluted for heavy soiling. This degreaser is especially effective when used in workshops feeding an effluent plant, as it is a quick split degreaser, and the separation of oil and water is greatly increased.

ProSolve 1 000 l

Environmentally friendly, non-emulsifying degreaser.

DIrections for Use
ProSolve can be used to clean a wide variety of items. It can be diluted for household use, and can be used undiluted for heavy soiling. This degreaser is especially effective when used in workshops feeding an effluent plant, as it is a quick split degreaser, and the separation of oil and water is greatly increased.

ProZorb 30 kg

Hydrocarbon absorbent.

Directions for Use
ProZorb is an absorbent that can be used on hard surfaces and also to contain hydrocarbon spills. Apply it to the contaminated area during absorption of the hydrocarbons – this will change the colour. Once complete, sweep it up and dispose correctly.

Terrazyme 20 kg

Ready-mixed microbial product on soil.

Directions for Use
Terrazyme is a microbe-based product. It is pre-mixed at the optimum ratio to treat hydrocarbon spills in soil and on harder surfaces. Dig the soil over until the deepest level of contamination is reached, and ensure all large clods of soil are broken up. Mix the Terrazyme into the soil thoroughly, and spray with water. The water then activates the microbes and remediation begins. The full remediation process will take between 14 and 21 days, depending on the severity of the spill.

Aquazyme 20 kg

Ready-mixed microbial product for use in water.

Directions for Use
Aquazyme is a microbial formulation, almost exactly the same as Terrazyme, with the only difference being that the ration is twice that of Terrazyme. The reason for this is that Aquazyme is used for water, and as the water instantly activates the microbes, additional microbes are required. The Aquazyme can be scattered on the surface of the body of water, as well as between vegetation in waterlogged areas.

Hydrocarbon spill kit 240 l

Emergency spill kit for use on spills of up to 240 l.

Directions for Use
Our spill kits come in a very wide range of sizes, and can be customised to suit each site’s specific requirements. The most common of these is the 240-litre spill kit, containing all that is required to clean a spill of up to 240 litres.
