The Crusader Multimedia Oxidizing (MM-OX) Filter

Operation of the Filter
Water can contain Iron (Fe), Manganese (Mn), and Hydrogen Sulfide (H2S). Soluble iron and manganese are oxidized and precipitated by contact with higher oxides of manganese on the proprietary blend of oxidation media. Hydrogen Sulfide is oxidized into an insoluble sulfur precipitate. Precipitates are filtered, retained, and then removed by vigorous back-washing. When the oxidizing capacity of the media is exhausted, the system has to be regenerated and sparged with ambient air, which makes it envirnmentally friendly.

Filtration Media
The media is specially formulated using a lightweight, synthetic granular core, which is coated with manganese dioxide. The proprietary media acts through both oxidation & physical filtration. The filtration system also includes a food-grade, FDA-approved gravel under-bedding to ensure uniform flow and consistent performance.

Controller/Meter
Regeneration of the system is initiated by a simplified electronic control timer, which electronically meters water flow to the home and makes decisions to regenerate based on water consumption and program settings.

Regeneration
These iron filters are controlled electronically. A fully programmable microprocessor controls Upflow Ambient Air Injection, Slow Rinse, Backwash, Rapid Rinse, Tank Fill, and Return-to-Service cycles.

Control Valve
A hydraulically balanced piston slides effortlessly through seals & spacers. All parts in the waterway are either coated brass or composite Noryl® materials to ensure a long and reliable service life.

Media Tank
All models feature a non-corrosive fiberglass tank with a one-piece thermoplastic inner liner. The tank has a maximum working pressure of 90 psi and a working temperature up to 120°F. The tank is approved by NSF, UL, and the FDA. It also meets WQA Standard S-100, and all fiberglass tanks carry a limited lifetime warranty.
