Since 1989 BlueStream Environmental Technology’s technical team has been developing effective and long-term solutions for waste disposal, especially all types of hydrocarbon fractions.
Now through AEBT developed exclusively to BlueStream, we are able to handle the bulk of clean ups, maintenance and environmentally sensitive issues in a tested and approved environmentally acceptable manner.
Through a proprietary blending of biological compounds and waste degraders we customize the treatment to ensure success.
In controlling environmental waste, each situation is unique. Therefore, special attention is given to the individual biodegradation needs of each application.
Field representatives with laboratory assistance are available to provide guidance for effective treatment programs and product application.
All products meet government and NOSA regulations and require no special clothing or equipment for handling.
Contamination of soil and groundwater comes from dozens of sources. The majority of these contaminants are organic compounds that can break down into something that no longer pollutes. Sometimes the environment can naturally break down pollutants over a long period of time. More often, site conditions, time constraints, business interests and risk evaluations require a faster remedy. AEBT has an established track record of quickly and effectively eliminating these pollutants.
BlueStream’s products are proprietary blends of biochemical and biologicals that are non-toxic and non hazardous. The Bioremediation absorbent product range absorb, encapsulate and digest contaminants derived from the entire hydrocarbon range. All produce better results in greatly improved completion times for in-situ or ex-situ remediation projects.
BlueStream products are non-toxic, non hazardous and will not harm the environment.
Our range of environmentally acceptable products are divided into two categories:
Cost effective, flexible and easy to apply, AEBT products are developed specially to supply safe, simple remedies for the clean up of contaminated soils and groundwater. The AEBT products contain armies of contaminant degrading microbes. These extra strength bacteria go to work to provide:
- Faster remediation
- Anaerobic capacity
- More resistance to toxins
- Multiple bacterial capability
- Thorough degradation
- Better activity
AEBT is used for:
- Oil Spills / Fuel spills
- Hazardous wastes
- Abandoned sumps
- Grease emulsification and disposal
- Land farming
- Truck / car wash systems
Applying AEBT is simple. There is no need for special equipment
AEBT works where others cannot by using bio-surfactants which release sequestered contaminants. Then the microbial populations break down all remaining contaminants into harmless carbon dioxide and water.
Guidelines to implement a AEBT program
Initially determine the outer limits of the polluted / soiled area [length width & depth], draw a diagram of the area and indicate where the soil monitoring samples will be taken. NB: If the contaminant has ingressed past a depth of 500mm it is recommended that the contaminant is removed and placed into wind rows or placed into long piles not exceeding a height of 500mm prior to implementing the AEBT program.
Monitor target contaminant concentration TPH, TP and nutrient concentrations such as ammonia-nitrogen, Ortho-phosphate soil pH by implementing the following monitoring program.
Establish the benchmark by taking soil samples of the contaminated area prior to implementing the AEBT program.
Commence the monitoring program 21 days after implementing the AEBT program and repeat every 21 days until acceptable levels have been achieved.
Take the soil samples at the points indicated on a diagram at a minimum level of 150mm, pack, mark and date the samples in a plastic bag or plastic container and forward to your or our laboratory for analysis. [250gm per soil sample]
Initially spray OilGone HB over the contaminated area by mixing @ a ratio of 1 part OilGone HB to 10 parts water.
Apply Organic SoilFix at a ratio of 4kg per cubic meter by applying it evenly over the contaminated area, till / dig in and thoroughly turn Organic SoilFix into the contaminated area and water well.
After seven days apply OSFN Organic SoilFix Nutrient and thoroughly till and aerate the soil and water liberally.
Tilling exposes the buried hydrocarbon mixture to the heat [photosynthesis] and leaves the soil aerated.
Turn the soil and water well weekly.
A moisture content between 30 and 49 percent of soil holding capacity should be maintained during the AEBT program.
What is BIOREMEDIATION?
Bioremediation is a natural process that uses micro-organisms to transform harmful substances into non-toxic carbon dioxide, water and fatty acids. There is an almost unlimited supply of information that supports the successful application of bioremediation for the clean up of contamination, backed by agency clean-up closure certification.
Micro-organisms, like all living creatures, require nutrients such as nitrogen, phosphate, carbon, water and environment to grow and survive. When these conditions are present, some micro-organisms will break down organic contaminants as a source of carbon for energy and growth.
We provide a combination of chemical, microbiological and process technology that is synergistic in eliminating contamination. In general, we use a biodegradable chemical application to disperse the contamination into very small droplets. With this solution there are nutrients, water, enzymes and microbes. Since many of the better microbes used to consume petrochemical contamination are aerobic, we also add slow oxygen release agents to our solutions. Each of these additives plays a role in making our process work. By breaking the contamination into small droplets we create an exponentially greater surface area for the microbes to have access to the contamination. Around each droplet is a life support environment for the microbes to flourish, which consists of water and nutrients. The enzymes present break the contamination down so that the microbes can consume the carbon. This is very similar to the metabolic process used by humans to break down fats, sugars and other food substances.
This process results in the contamination being metabolised by the microbes into harmless carbon dioxide and water. When the food source is depleted the microbes die off and the contaminated site is returned to its pre-contaminated state. All of our solutions, including microbes are non-pathogenic, non-toxic, non-carcinogenic and biodegradable.
Over long periods of time and without human intervention, nature eliminates both natural and most man made pollution. This happens as naturally occurring micro-organisms, enzymes, chemicals and weather combine to eliminate toxins. Recent advances in technology have made it possible to greatly accelerate these natural processes by selecting, concentrating and acclimating micro organisms to attack and eliminate many hydrocarbon based toxic materials in a matter of weeks rather than decades. The use of these micro-organisms to consume and eliminate dangerous or unwanted hydrocarbon based contaminants like petroleum products is called bioremediation. Bioremediation can achieve the elimination of contamination in many environments with a speed and thoroughness much greater than traditional methods and at significantly lower costs.
The process is fundamentally simple. Contaminants like creosote, fuel oil, toluene, and even PCBs are composed of carbon chain molecules. Some of the most toxic hydrocarbon contaminants also contain chlorine. Although too complex or too toxic for most living organisms to metabolise, there are naturally occurring micro-organisms that can be cultured to attack these compounds. When these micro-organisms, along with materials that provide them with other requirements like oxygen, are put in contact with the contaminants, they attack the complex hydrocarbon molecules and break them down into harmless by-products. In the process the micro-organisms ultimately die, leaving nothing but harmless organic residues like any other micro-organisms leave behind.
The versatility of this method of clean up is remarkable. In many cases bioremediation can be used without any significant site disruption. For example, hydrocarbon contamination in aquifers can often be treated by injecting the micro-organisms into the well where they follow the contaminant plume and reduce the contamination to harmless materials. In some cases oil contamination can be eliminated with topical applications. In other cases the micro-organisms may need to be introduced into the soils with mechanical assistance like deep ploughing of the soils. In the more extreme cases the contaminated soils may be put into large containers where they are treated with the organisms and then returned directly to the site.
Unique application potentials also exist. For example, contamination under concrete slabs can be remediated by introducing the organisms with horizontal boring or through the slab borings. This can eliminate the need for removal of slabs or buildings as traditional clean up processes would require. The economics of bioremediation are almost always significantly more favourable than other techniques. The primary reason is that there is no need for the hauling and expensive disposal costs of contaminated soils.
On sites where contamination is confined to clearly defined areas it can be possible to begin the development process on the clean areas while bioremediation is in progress on the remainder of the site. This is possible because the process is generally not very disruptive and does not require the removal and replacement of large amounts of soil. Furthermore, while conventional remediation often just moves the pollution from one place to another, bioremediation actually eliminates the unwanted materials. Bioremediation should be considered as an environmentally and economically desirable option for any site where hydrocarbon based remediation is required.
Procedures for using :
Procedure for treating Oil Spills on Soil
The following procedure is to be used to treat surface spills on soil (up to a maximum ingress of 100mm). For heavily contaminated soil, see procedural document 002.
- Turn the soil to be treated with a shovel or fork
- Pour OilLift over the entire area and leave to react for approximately 20 minutes. The OilLift will oxidize the contaminant.
- Once OilLift is no longer reacting, turn the soil again.
- Water with OilGone WB (diluted 5:1 with water) over the area and turn soil again. This will help to restore the pH of the contaminated soil.
- Spread a layer (approximately 10mm) of Organic SoilFix over the area, and turn the soil, mixing well. Water area well over the next 6 weeks. This will ensure the complete removal of any hydrocarbons or oils.
Procedure for treating Heavily Contaminated Soil to top
Where soil has been saturated with oil to depths more than 100mm, the following procedure must be followed. (For depths 100mm and less, see procedure document 001)
- If the depth of contamination is more than 500mm, the soil should be dug out and placed in heaps of approximately 1 cubic metre, half a meter high. If less than 500mm, the soil can be treated where it lies.
- Mix 3kg Organic SoilFix into every cubic metre of contaminated soil.
- 3)Mix the Organic SoilFix Nutrient that is supplied in each bag of Organic SoilFix (250ml), with 5 litres of water.
- The diluted Nutrient should be sprinkled/sprayed over the soil at a rate of 1,5 litres per cube of soil being treated.
- If the soil was removed as per point above, it should now be placed back where it came from.
- The entire area must be watered thoroughly .
- The area should be watered at least once a week, preferably twice, and the soil turned on a fortnightly basis.
- If Organic SoilFix Liquid is used, the procedure is the same as above, except that no Nutrient needs to be added, and the dosage is 2 litres per cubic metre of contaminated soil.
Procedure for the use of EcoWizz GP and OilGone WB to top
EcoWizz GP is a non-solvent, water-based General Purpose Degreaser for use on all surfaces contaminated with oils – machinery, floors, tiles, etc. OilGone WB is a non-solvent, water and Citrus Oil based Degreaser for use on the same surfaces, but for more stubborn contamination.
- EcoWizz GP and OilGone WB can be poured onto floor surfaces and agitated with a hard broom or a cloth.
- EcoWizz GP and OilGone WB can be poured onto a cloth to clean vertical surfaces or machinery. Simply wet the cloth with EcoWizz GP or OilGone WB and rub the area.
- Wash the newly cleaned area with water.
- Depending on the application, OilGone WB can be diluted up to 5:1 and EcoWizz GP up to 2:1, although both are more effective undiluted.
Procedure for the use of OilLift on Hard Surfaces and Ballast to top
OilLift is the only product in the BlueStream range that is not safe to use without protection. Gloves and Goggles should always be worn. See MSDS for more details.
A) Hard Surfaces
OilLift is ideally suited to porous surfaces like concrete and paving where oil has seeped into the contaminated surface and needs to be ‘fetched’ out.
- Pour OilLift onto the hard surface to be treated, and scrub with a hard broom.
- Leave OilLift to react with the oil, and penetrate the surface. OilLift should be left to oxidize the oil, turning it into dust, for at least 20 minutes or until it finishes reacting.
- When it is finished reacting, wash the surface with water
- The procedure may need to be repeated as the ingressed oil rises to the surface over time
B) Railway Ballast
- Spray or pour OilLift over the contaminated stones and leave to react
- OilLift may be sprayed on with a portable ‘backpack’
- Leave for 20 minutes or until reaction has ceased and the wash off with a pressurized stream of water (e.g. Portable backpack).
