BIOREMEDIATION IN PARTS CLEANING

FACT AND FICTION

By: Onofre Ortiz and Thomas W. McNally

slide2

BIOREMEDIATION :

Definition

Degradation of organic matter using microorganisms

(bacteria, fungi & algae)

FACT AND FICTION

By: Onofre Ortiz and Thomas W. McNally

slide3

BIOREMEDIATION Cycle :

bacteria

bacteria reproduce

secretes enzymes

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

bacteria excretes CO2 and water

bioremediation via biodegradation
BioremediationviaBiodegradation

(the breakdown of organic substances by microscopic organisms)

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

system advantages
SYSTEM Advantages :

Bioremediation is a Natural and Safe Process.

FACT AND FICTION

By: Onofre Ortiz and Thomas W. McNally

system advantages11
SYSTEM Advantages:

Bioremediation eliminates the need for transportation of spent solvents and other hazardous materials.

FACT AND FICTION

By: Onofre Ortiz and Thomas W. McNally

system advantages12
SYSTEM Advantages :
  • Bioremediation can remediate the contaminants (in situ) in place, and does not generate waste products.

FACT AND FICTION

By: Onofre Ortiz and Thomas W. McNally

system advantages13
SYSTEM Advantages :
  • Bioremediation allows for minimal environmental impact.

FACT AND FICTION

By: Onofre Ortiz and Thomas W. McNally

system advantages14
SYSTEM Advantages:
  • Bioremediation completely breaks down contaminants to innocuous end products.

FACT AND FICTION

By: Onofre Ortiz and Thomas W. McNally

system advantages15
SYSTEM Advantages :

Bioremediation is more economical than traditional technologies.

Question: How Safe Are Microbes?

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

Question: How quickly can microbes breakdown contaminants?

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.

FACT AND FICTION

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

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.

FACT AND FICTION

By: Onofre Ortiz and Thomas W. McNally

fact and fiction20
FACT AND FICTION

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

By: Onofre Ortiz and Thomas W. McNally

fact and fiction21
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

slide22

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

slide23

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.
