THE PROBLEM: Sediment and debris in secondary containment

Did you know that sediment and debris are the most common causes of hydrocarbon stop valve failures in secondary containment? Our studies prove that 90%+ of expensive hydrocarbon filter valve shut-offs are due to plugging from suspended solids – (not from petroleum). In addition, many facilities replace tens of thousands of dollars worth of petroleum filter valves every year because of sediment, not oil.

THE SOLUTION: Control sediment and extend the life hydrocarbon stop valves with Silt Trap Socks

After studying the problem side-by-side with our clients, we engineered an innovative pre-filter system that extends the life of these oil-water filters. Drainiac® Silt Trap Socks are the first line of defense against sediment and debris contamination.
