BIOREMEDIATION :Definition

(bacteria, fungi & algae)

FACT AND FICTIONBy: Onofre Ortiz and Thomas W. McNally

BIOREMEDIATION Cycle :


secretes enzymes

enzymes attack grease, fats, oils – which allow the bacteria to eat the broken

down pieces.

bacteria excretes CO2 and

water

bacteria reproduce

Bioremediation via Biodegradation

bioremediation is the use of biodegradation to break down pollutants in soil, air or groundwater.


(the breakdown of organic substances by microscopic organisms)

BIOREMEDIATION : ApplicationsParts Cleaning


SEQUENCE OF EVENTS :

Carbon based contaminants are removed from repair parts by surfactants.

SYSTEM Advantages : :


Bioremediation is a Natural and Safe Process.

SYSTEM Advantages ::

Bioremediation eliminates the need for transportation of

spent solvents and other hazardous materials.




Bioremediation can remediate the contaminants (in situ) in place, and does not generate waste products.



Bioremediation allows for minimal environmental impact.


Bioremediation completely breaks down

contaminants to innocuous end

products.

SYSTEM Advantages ::



Bioremediation is more economical than traditional technologies.

Question: How Safe Are Microbes?

FACT AND FICTION


Answer: Classified American Type Culture Collection (ATCC) Class I Organisms are nonpathogenic, completely safe to use and have no recognized hazard potential under ordinary conditions of handling.

Answer: This classification is assigned only after extensive study and review by ATCC and government committees.

Answer: Class I Organisms are subject to unrestricted

distribution by the ATCC, U.S. Department of Health, Public Health Service and the Toxic Substances Control Act (TOSCA).

FACT AND FICTION


Answer: Once active, the rate at which the microbes can remediate hydrocarbons can approach 80% every seven days. Analyses performed on samples of used surfactant taken from a bioremediating parts washer operating consistently show oil and grease levels in the 1,400 parts per million range. BY COMPARISON, used, non-bioremediating, aqueous cleaners can average over 20,000 parts per million of oil and grease.

Question: How quickly can microbes breakdown contaminants?

Not Just Any Class of Microbe: how it works


FACT AND FICTION


Answer: As with all parts cleaners, excessive greases, oils and fluids should be disposed of prior to washing parts and NOT used as a waste oil dump. That said, most bioremediating parts washers can handle large, tough, dirty jobs.

Question: How much oil can I put into a bioremediating parts washer at one time?

Answer: YES. The bioremediation process that takes place in the solution frees the surfactants allowing them to clean and emulsify even more contaminants.

Question: Do microbes improve the cleaning ability of aqueous cleaners?

FACT AND FICTION


FACT AND FICTION


Question: In addition to oil, will bioremediating parts washers clean other substances?Answer: Microbes have been successfully

used on a variety of contaminants including the following:

CRUDE OIL OILS SOLVENTS BTEX GREASES

AMINES CREOSOTE PHENOLS PCP FATS PNA

FACT AND FICTION

Question: Do the microbes need to be in a heated environment to survive?Answer: Microbes will slow down their

remediation and reproduction rate but not die at low temperatures. The microbes work at a more efficient rate in a warmer environment and it is a more enjoyable cleaning experience for the user if the solutions are heated. FACT AND FICTION

By: Onofre Ortiz and Thomas W. McNally

FACT AND FICTION


Question: Is there anything that could kill the microbe in a bioremediating parts washer?Answer: YES. Any biocides designed to kill

microbes, such as bleach or chemicals that kill living things like some strong pesticides and rat poisons.

Bioremediation represents the safe, effective and sustainable

method for parts cleaning.
