Target Contaminants:
Persulfate-based ISCO is effective for a wide range of compounds, including:
+ Petroleum hydrocarbons (BTEX, TPH, PAHs)
+ Fuel oxygenates (MTBE, TBA)
+ Chlorinated ethenes (PCE, TCE, DCE, vinyl chloride)
+ Chlorinated ethanes and methanes
+ 1,4-dioxane
+ Pesticides
TSI-FSA™ Activation:
Terra Systems’ TSI-FSA™ ferrous sulfide activation provides a safer and more controlled alternative to traditional activation methods:
This Approach:
+ Reduces safety risks for field crews
+ Minimizes damage to injection equipment
+ Improves treatment efficiency
+ Helps reduce overall project costs
