Treatment

The first step in the treatment of a Fire Protection System that is experiencing MIC is to thoroughly clean or flush the system.

Cleaning involves injecting the system with a non-toxic, bio-degradable cleaner and allowing it to soak overnight to remove loose deposits and adherents. Flushing is done at a high enough volume and velocity to achieve the same result.

Removing as much of the deposits and adherents as possible helps restore the flow rate of the system and allows for effective treatment of the pipe.

The next step in treating MIC is the injection of a non-toxic, bio-degradable corrosion inhibitor into the fire sprinkler system.

The inhibitor protects the pipe by creating a protective layer on the pipe that prevents oxygen and MIC bacteria from penetrating to the pipe and causing corrosion.

If the layer is scratched or damaged, maintenance levels of inhibitor in the area repair the damage and maintain the protective layer.

The layer is only one molecule thick and does not interfere with the performance of the fire sprinkler system.

As an option, treating both wet and dry sprinkler systems with Nitrogen adds even greater protection against oxygen corrosion and aerobic bacteria. A Nitrogen Generator will pressurize a system with Nitrogen gas and eliminate nearly all the gaseous oxygen and remove dissolved Oxygen from the water.

Minimizing Oxygen corrosion makes it more difficult for MIC to start a colony.

A Fire Protection Systen that is treated with inhibitor and pressurized Nitrogen provides the greatest corrosion protection available with present technology.

Treatment also includes installation of a Corrosion Monitoring Station.

A Corrosion Monitoring Station contains Corrosion Coupons that can be pulled periodically and tested to ensure there has been no recurrence of MIC.

The Corrosion Monitoring Station can be isolated from the fire sprinkler system to allow the coupons to be pulled without putting the entire system into Test mode.

Corrosion Monitoriing Stations are installed in both wet and dry systems.
