Commercial Filter Systems
Commercial Iron Curtain Filter Systems
Our patented Iron Curtain Filtration Systems are designed to remove iron and hydrogen sulfide without the use of potassium permanganate, chlorine or salt.
This results in much lower operating costs, and the problems associated with hazardous chemicals.
10″ – 72″ diameter filter vessels are available in single and multi-tank designs with a wide range of controls.

- 1.25″, 1.50″, 2″, and 3″ valves
- Regeneration based on calender, volume, or pressure drop
- 9 cycle operation with multiple backwash and rinse options
