• VTX is an organic catalyst that reacts with various oxidizing agents to produce hydroxyl radicals.
• No sludge is produced as a result of the process in normal use.
• Safe and easy to apply.• Application of catalyst requires no
materials of special construction.

The VTX ProcessTreatment of Sulfide• VTX rapidly converts
sulfide (H2S, HS-, S=) to elemental sulfur.
• Immediate reduction of odor and corrosion due to H2S.
• VTX is suited for control of sulfide in:

Reaction Time and Dosage Comparison:
H2O2 Alone vs. VTX ProcessTreatment of Hydrogen Sulfide
Hydrogen Peroxide AloneH2S + H2O2 S0 + 2H2OReaction time: 20-30 minutesEffective dosage (mass H2O2/mass H2S): 1.5 to 4.0 : 1.0
VTX ProcessH2S + VTX /H2O2 S0 + 2H2O + salts + CO2 + [VTX]*Reaction time: <3 minutesEffective Dosage (mass VTX/mass H2S): 1.5 to 2.5: 1.0* Note: [VTX] = remaining un-reacted VTX
