Wastewater Infrastructure Protection
ProSec 201 & ProSec 203 are specially formulated mortars for the protection of wastewater infrastructure against biogenic sulfuric acid corrosion (BSAC). Technology utilizing calcium aluminate cement against BSAC has more than 70 years of track record globally.
Sewerage Systems - How does corrosion happen
Mechanisms of Biogenic Sulfuric Acid Corrosion (BSAC)
Biogenic sulfide corrosion is a bacterially mediated process of forming hydrogen sulfide gas and the subsequent conversion to sulfuric acid that attacks concrete and steel within wastewater environments. The hydrogen sulfide gas is biochemically oxidized in the presence of moisture to form sulfuric acid.
How Does ProSec 201 & ProSec 203 Work Against Biogenic Sulfuric Acid Corrosion (BSAC)
ProSec 201
A ready-to-use mortar for protecting wastewater infrastructure against severe biogenic corrosion related to hydrogen sulfide found in wastewater environments. Made with Calcium Aluminate Cement and Aggregate.
ProSec 203
A polymer-modified mortar for protecting/rehabilitating sewer structures. Formulated with Calcium Aluminate Cement as a key binder.
