Hydrotech AIO Series Water Filter

Intended to be an effective and economical way to remove iron from water without the use of messy and dangerous chemicals or expensive pumps or an external venturi. The AIO valve uses a unique process to create an air bubble at the upper portion of the tank to oxidize any ferrous iron prior to being filtered by the media. It can also be used to remove low concentrations of dissolved hydrogen sulfide and manganese from water.

This filter works by adding oxygen to the incoming water by passing it through a bubble
of compressed air. The water is then passed through a special filter bed. The special media
not only increases the pH of the water to enhance iron removal but also acts as a physical
barrier to trap iron precipitate. As more water passes through this iron filter, the oxygen
in the unit is used up, and the media gets loaded with iron. The regeneration process then begins in order to replenish the supply of oxygen, and to backwash the precipitated iron trapped in the media bed. The iron removal efficiency will be more effective with high pH water. The filter is fitted with an inlet check valve to prevent any air from flowing backwards out of the filter tank.
