Microbiologically Influenced Corrosion (MIC)
Damage (Bacterial Proliferation)

 

Microbiologically Influenced Corrosion (MIC) Damage (Bacterial Proliferation) is a major cause of failures in pipelines & process equipments

  • What is Microbiologically Influenced Corrosion (MIC)?
  • How to “enzymatically” control and remove MIC?
  • Introduction to … CoryoZyme

… an innovation designed to enzymatically manipulate bacterial behaviour and economically deliver numerous benefits …

About CoryoZyme

Organic product designed to deliver the desired end results naturally, without side effects or residual pollutants, as do synthesized chemicals.
A unique and indigenous Enzyme based treatment designed to manipulate local bacteria found in …

  • industrial effluents to eliminate microbiological influenced corrosion in pipes and process equipments
  • sewage networks and treatment plants to rapidly digest biodegradable waste

Our proprietary process involves the use of Enzymes fermented in controlled fermenters from heterotrophic non-pathogenic decomposing bacteria.
A tailor made treatment process involving the continuous release of specific enzymes from specially designed sustained release packs.
These enzymes are very active in targeting and degrading complex organic matter.

 

What is MIC?
• MIC is an acronym for microbiologically influenced corrosion, a mode of corrosion incorporating microbes that react and cause the corrosion or influence other corrosion processes of metallic materials.
• MIC is caused by specific genera of bacteria which feed on nutrients and other elements found in Fresh, Salt and Brackish waters.

How do they (microbes) form and induce corrosion?
• In the presence of nutrients (metals), water, and oxygen … Microbes … are capable of forming slime or “Biofilms” on the surfaces of metals.
• These Biofilms provide the environment for Bacterial growth activity to form corrosive products / byproducts causing corrosion of surfaces.

Types of Micro-organisms involved:
• Aerobes (GAB) … … oxygen consuming
• Anaerobes (GAnB) … non-oxygen consuming
• Groups categorized as … …
– Acid producing, Sulphate reducing (SRB), Nitrate and Iron reducing biofilms
– Gallionella, Sphaerotilus, Pseudomonas, Klebsiella, Eneterobacter, Acinetobacter, Bacillus, Aeromonas, and Legionella

What are Biofilms?
• Biofilms are capable of colonizing virtually any surface on earth and they are extremely difficult to kill.
• In industry, biofilms can be found adhering to surfaces in most aqueous environments, such as those of a pipeline wall or the tubes of a heat exchanger.
• Biofilm formation begins when a single planktonic bacterium attaches to a surface by weak Van der Waals forces
• Established biofilms consist of millions of cells in mats … many thousands of layers deep, completely encased in a … dense polysaccharide complex … that renders them virtually impervious to antibiotics and chemical poisons (viz. … biocides)

Five stages of biofilm development:
(1) Initial attachment
(2) Irreversible attachment
(3) Maturation I
(4) Maturation II
(5) Dispersion
    • Dispersal of cells from the biofilm colony is an essential stage of the biofilm life   cycle
    • Dispersal enables biofilms to spread and colonize new surfaces
    • Nitric oxide has also been shown to trigger the dispersal of biofilms of several bacterial species

Mature biofilm formations behave like a … “single living organism” They also may move collectively across a surface or detach themselves in clumps as a means to spread, colonize and damage new surfaces.

How CoryoZyme helpscontrolled and remove MIC Biofilms?

The enzymes in CoryoZymehelp prevent Planktonic bacteria from forming Biofilms, thereby, reducing the number of sessile bacteria plaques in the water downstream of the dousing.
The enzymes will also help destroy existing biofilm plaques on the coupons thereby increasing the life of the coupons.

Five stages of where CoryoZyme will stop biofilm development:

  1. Initial attachment – will digest the polysaccharides required to attach bacteria to surfaces(Inhibits)
  2. Irreversible attachment – will digest polysaccharides, thus dislodge fresh bacteria trying to start colonies(Clears)
  3. Maturation I – It will digest the biofilms, exposing the bacteria and stop them from spreading
  4. Maturation II – It will digest the biofilms, exposing the bacteria and stop them from spreading
  5. Dispersion (Arrests)

Are Biocides required with CoryoZyme? CoryoZyme … digests the polysaccharides thus dislodging and exposing the bacteria … thereby allowing Biocides to … penetrate, accomplish and deliver … the required results.

Where to douse CoryoZyme?
CoryoZyme …
Dousing is done UPSTREAM …

  • of all trouble spots …
  • in all water streams …

where BRW, RCW, PDW and EFW have largepopulations of Sessile GAnB’s.
