Automatic Iron Reduction System

Dissolved (ferrous) iron above 1.5 ppm can only be effectively reduced by first oxidizing it to precipitate it into a physical form (ferric) and then entrapping those physical lumps.

The AIRS 1252 is a fully automatic manganese greensand filter that performs all of these requirements in the one unit. With either the fully automated or microprocessor head, the AIRS 1252 is almost a set-and- forget system.

Reduction in iron concentrations can be quite dramatic depending upon other constituents present in the water, but upwards of 95% reduction is not uncommon. In worst case situations, reductions of around 80% might only be achievable.

A 460i Control Head actually measures volume throughput and regenerates the greensands with more timely accuracy than a standard clock day timer.

The brine tank holds potassium permanganate (KMnO4) used to regenerate the manganese greensands during the back flush and wash cycle.

It is important that the drain to waste does not flow directly into natural waterways.

Greensand is a naturally occuring mineral that consists of large dark greenish grains of glauconite. Manganese greensand is processed to incorporate the higher oxides of manganese into its pores and onto its surface.
