CONTAINMENT

MJCS has extensive experience working on potable water projects that require ANSI/NSF 61 certification for safe drinking water. These applications demand coatings that can bridge cracks, adhere to various substrates, withstand movement when tanks are filled, endure thermal shock, cure rapidly, and offer long-term durability.

Our potable water applications include:

Potable water storage tanks and reservoirs
Primary and secondary chemical containment
Chlorine contact chambers
Clearwells
Flocculation basins
Filter beds

For wastewater treatment plant (WWTP) applications, biogenic sulfide corrosion and the formation of sulfuric acid from hydrogen sulfide exposure can severely damage concrete surfaces in sewer environments. Concrete, composed of sand, rock, and cement, is particularly vulnerable to these effects, as the cement’s mineral mix is prone to attack from hydrogen sulfide and acid. The rate of concrete degradation is influenced by the concrete’s permeability and the concentration of hydrogen sulfide in the environment. Signs of acid attack include rust bleeding, cracking, and spalling of concrete. M has successfully implemented concrete rehabilitation and applied long-lasting coatings that resist H2S, sulfuric acid, and UV exposure in numerous WWTP facilities across the U.S.

Our wastewater applications include:

Aeration basins
Lagoons
Lift stations
Oxidation systems
Digesters
Clarifiers
