OxiPlus12™ is an NSF/ANSI/CAN-61 certified catalytic media used to remove soluble iron, manganese, hydrogen sulfide, arsenic, and radium from groundwater. The media consists of a silica sand core coated with manganese dioxide (MnO2). The combination allows the media to catalyze the oxidation-reduction reaction of iron and manganese while tolerating water that is low in silica, TDS, and hardness without breaking down. OxiPlus12 is an ideal choice for retrofitting existing sand/anthracite and greensand filtration systems. OxiPlus12 is manufactured with a minimum 12% MnO2 coating vs 4.5-5% for competitive products. This results in longer run times between backwashing events, thus reducing system downtime and water to drain. Additionally, OxiPlus12 is produced in a mesh size of 18x45 rather than 18x60, significantly reducing the quantity of media sent to drain during the initial start-up of the system.

OxiPlus75™ is a highly effective media for the removal of iron, manganese, arsenic, radium and hydrogen sulfide. This robust filter media has proven highly successful in municipal and industrial pretreatment applications where manganese is in the water.

For media replacement/retrofits, consider OxiPlus12. Reduced system footprint sizes due to the catalytic properties of OxiPlus75 allow for high filter loading rates while maintaining high treatment efficiency. High volume backwash rates result in reduction in total backwash volumes as compared to standard sand-anthracite or greensand applications. OxiPlus75 is NSF/ANSI/CAN-61 Certified and highly effective in drinking water applications. Long media life allows for economical water treatment operation. When used with an oxidant such as sodium hypochlorite, longterm performance and capability of the media is maintained.
