Microbially induced corrosion (MIC): triple filter beats MIC with its own weapons

No herb can be used against microbially induced corrosion (MIC), but a filter can. Several providers share the market — the Coalsi system has a threefold effect.

Microorganisms that produce foul-smelling hydrogen sulphide as a metabolite are considered to be the main MIC triggers in buildings and technical facilities. Wastewater plants are particularly at risk. Air filters reduce the risk by reducing the concentration of pollutants in the environment.

The Coalsi solution is a filter cascade of chemical, physical and biological elements. In essence, the manufacturer is fighting the polluter with its own weapons: Microorganisms in one of the filter modules “eat” the harmful metabolites and thus reduce their concentration — in many cases up to the olfactory detection limit.

The manufacturer offers its solution as an insert filter for street sewers, as a pipe filter and as a stationary device for large air volumes. The filters are flowed through the entire surface. They are neither human, plant nor animal pathogens. The replaceable filter mats last up to three years.
