Eliminate rust staining, as well as sulfur “rotten egg” odors with the Nelsen AIO™ 

Air Injection Oxidizing Systems.

Iron and Sulfur are two of the most common elements found in nature. While both are extremely important for everyday life, both are a nuisance in water and can cost you money and frustration.  Iron staining is a common problem in homes today. It causes orange staining on fixtures, as well as dingy clothes and sometimes can have negative effects on both hair and skin. Sulfur is easily detected by the presence of a “rotten egg” odor, and is sometimes associated with yellow staining. All of these problems can be eliminated with the Nelsen AIO™ Air Injection Oxidizing Filtration System. 

Using Nature’s Own Process

These naturally occurring elements can be removed using nature’s own process of oxidation. The Nelsen AIO™ maintains an “air pocket” in the top of the tank while the system is in service. As water passes through the air pocket, iron and sulfur are oxidized. The Nelsen AIO™ filter media bed then removes the oxidized iron and sulfur from the water. Additionally, dissolved oxygen is added to the water. 

Proven Technology  

The Nelsen AIO™ system includes the Pentair Fleck 2510AIO SXT or 5600AIO SXT electronic control valve that automatically backwashes the system to clean the media and flush everything down the drain. The Nelsen AIO™ puts the whole oxidation process inside one tank, keeping maintenance costs and down time to a minimum. Made by Pentair Fleck, a leading manufacturer of control valves in the US, the digital control valve allows for ease of setup and automatic operation. The Nelsen AIO™ can remove up to 8 ppm Hydrogen Sulfide and up to 7 ppm Iron. A daily backwash will remove accumulated iron and replenish the filter media bed. The regeneration process also adds a fresh air pocket to the system. Calcium and hardness can also be removed when a water softener is placed after the Nelsen AIO™.
