Protecting assets - Corrosion protection Corrosion hazards with Anaerobic digestion. Hydrogen Sulphide (H2S) - up to 1500ppm Mixed with water produces Sulphuric Acid (H2SO4) Attacks concrete and damages steel Often goes undetected
Protecting assets - Corrosion protection Problem Corrosion is part of the process Solution Long lasting protection Guaranteed protection against chemicals
