Bio Probes monitor microbiologically influenced corrosion.

Press Release Summary:



Models 6205 and 6215 provide plant operators with functionality needed to collect samples for subsequent microbiological analyses in systems susceptible to microbiologically influenced corrosion (MIC). These retractable and retrievable bio-probes enable safe collection of sessile bacteria samples deposited on metal surface. Both have 5 sample elements, each with exposed frontal area of 1 cm², and serve as indicator of MIC level for correct and effective use of biocide treatments.

Rohrback Cosasco Systems Launch New Bio Probes for Monitoring Microbiologically Influenced Corrosion (MIC)



Rohrback Cosasco Systems now offers both retractable and retrievable bio-probes for monitoring microbiologically influenced corrosion (MIC). Corrosion monitoring Bio-probes offer plant operators a simple and effective tool for collecting samples for subsequent microbiological analyses in systems susceptible to MIC. Microorganisms, including bacteria, algae, and fungi can accelerate the corrosion process up to 1000 times. MIC is often undetected in many industrial systems but its importance should not be underestimated or ignored. Microbiologically induced corrosion can result in the improper use of corrosion inhibitors and coatings, resulting in significant waste and increased operating costs.

The most common forms of corrosion associated with MIC include pitting corrosion, uniform corrosion, crevice corrosion, galvanic corrosion, and stress corrosion cracking. Microbiological induced corrosion occurs in virtually every aqueous environment such as water treatment and sewage handling and treatment plants. MIC can also occur in oil & gas systems, chemical processing plants, and underground pipelines. Plant operators use chemical treatment, mainly biocides to kill the corrosion causing bacteria and other microorganisms in order to prevent or reduce corrosion. Physical cleaning or mechanical cleaning can control the effects of microbiological induced corrosion. However bio-probes are required for verification and adjustment of the treatment for effectiveness is recommended.

Cosasco Model 6205 and 6215 bio-probes provide an economical and safe means of collecting samples of sessile bacteria deposited on the metal surface in the process. The bio-probes have five sample elements, each with an exposed frontal area of 1cm². Each time a sample is required for analysis a successive element is removed and replaced with a new one, leaving the other four in place. With this successive change of elements, a longer exposure is obtained for each element, but still permits a relatively frequent sample to be taken for analysis.

Early detection is the key to controlling microbiologically influenced corrosion once it has infected the system. Once the microorganisms have formed a bio-film, they become more resistant to biocides and can rapidly grow if not detected and controlled. Cosasco Model 6205 and 6215 retrievable and retractable bio-probes offer:
  • Simple and economical means of collecting bacteria samples for corrosion monitoring
  • Indicator of level of microbiologically induced corrosion for the correct level and effective use of biocide treatments. This significantly reduces costs and minimizes dangerous effects to environment
  • Flush Probe with retrievable and retractable design ideal for frequently pigged pipelines
  • Use in high or low pressure system, without the need for system shutdown
