System - Biofilm Activity Monitoring System
in cooperation with Structural Integrity Associates now offers the BIoGEORGE
system - a simple, rugged, dependable system for real-time monitoring of:
- Microbiologically influenced corrosion (MIC)
- Biofouling of heat exchangers
- Biocide effectiveness
- Optimization of treatments: Selection, Timing, Concentrations
Microbiologically Influenced Corrosion (MIC) is a significant degradation
mechanism in nuclear and fossil-fuelled power plants, chemical processing,
refineries, pulp and paper, oil and gas production and distribution and the
armed services. Essentially all cooling water and process water applications
may be susceptible to MIC. Further, biological fouling, which is always a
precursor to MIC, can reduce the efficiency of heat exchangers and fluid
distribution systems and can interfere with water-based processes.
The most common approach to mitigation of MIC is chemical treatment.
Chemical costs for a large process plant are often on the order of $1,000,000
per year. Chemical toxicity is always a concern for plant personnel and the
environment. This results in close scrutiny and control of effluents and
chemical inventories by regulators, environmental agencies, and plant owners.
The BIoGEORGE system was developed to provide online and real-time indications
of biofilm activity on typical metallic surfaces. The probe is designed and
operated so that micro-organisms in the environment are encouraged to settle on
probe surfaces well before they settle on heat exchanger tubes or piping.
Probe status is indicated on the integrated electronics enclosure by an LED
display (red light/green light).
By closely tracking biofilm activity on the probe, the operator is alerted to
the need to treat the system, to assess the effectiveness of a treatment, to
schedule maintenance activities, or to optimize chemical treatments.
The system consists of a probe, its integrated electronics, interconnecting
cable, display software, User's manual, and product support.
The probe is installed into a piping system, heat exchanger water box,
cooling tower, or side stream via a 2-inch threaded connection. Special probes
can also be built for "hot tap” type fittings or flow-through probes.
The unit operates on a 110 or 220 VAC and has built-in battery backup.
System data can be downloaded to the user's PC. Software is included with the
system for analysing the data and creating detailed trend plots.
