You ask and we answer! MgWater Technical Director Matt Madolora offers solutions to common water treatment problems.

QUESTION: For corrosion protection, how does magnesium hydroxide compare to caustic soda and lime? 

ANSWER: Unlike quick-reacting caustic soda or lime, magnesium hydroxide has a controlled, sustained release of alkalinity. This slow-reacting property ensures longer-lasting pH stabilization, providing continuous protection against corrosion and odor over time. Corrosion is common in wastewater systems due to sulfuric acid formation from hydrogen sulfide.

THIOGUARD®, a 60% magnesium hydroxide slurry, creates an alkaline environment, preventing acid production and extending the life of pipes, lift stations, and wastewater treatment plant infrastructure. Cities using THIOGUARD® have seen lower pipe degradation and fewer repairs, lower maintenance costs over time, and better asset longevity without extra equipment.
