More importantly, what is the concentration? Even the same chemical at different concentrations can have vastly different impacts on geomembrane performance. A geomembrane that comfortably contains 10% sulfuric acid might suffer severe oxidative degradation if exposed to 98% concentrated sulfuric acid. Never assume a liner is simply "acid-proof"—you must match the polymer to the exact chemical composition and percentage.
