Aldex OSM Series

Aldex OSM+ (One Step Media) Hardness, Tannins, Fe, Mn, H2S Removal

Aldex OSM+ multi-component, universal, water treatment media is specially designed for the removal of the most common contaminants found in potable water. Aldex OSM+ is manufactured using only ANSI/NSF/CAN 61 certified components: a uniform particle size, strong acid, cation resin for hardness removal; a macroporous strong base, type 1 resin for removal of tannins and other anions; as well as CR 26, a novel resin able to further reduce dissolved metals and arsenic, should those species be present. There are many treatment options on the market but only Aldex OSM+ has the unique ability to offer high capacity and long life.

Benefits of Aldex OSM+

Blended for the North American Market

Aldex OSM+, manufactured in our plant in Granby, QC, is a blended product tailored to the North American market where the vast majority of installed systems are operated using a cocurrent design.

Aldex OSM+ is comprehensive by design with the exception of under-bedding. While coarse sand or gravel is commonly used the option is left to the installer as to which under-bedding is best for support and distribution.

Similarly, since there are virtually no packed bed residential systems and very few commercial packed bed systems operating in North America, Aldex OSM+ contains no floating resin. Aldex OSM+ uses no volume-filling inert plastic bead (as many companies do) but includes ion exchange resins able to remove hardness, tannins, iron, manganese and hydrogen sulfide.

 

Aldex OSM+ Features

Hardness

Aldex OSM+ contains a significant percentage of a high-capacity, uniform particle size, strong acid cation softening resin, Aldex C800 UPS. Aldex OSM+ will provide 15,000 grains operating capacity when regenerated with 12 lbs NaCl/cu ft. The Aldex C-800 UPS technical bulletin can be used to determine the pressure drop and backwash flow rate required to achieve 40-50% bed expansion.

Metals

Aldex OSM+ incorporates a unique chelation media able to oxidize metals in solution. Those metal-oxide nano-particles are then deposited in the void volume and removed with each regeneration. Many metal-oxides bind with arsenic so if arsenite or arsenate are present in solution, the Aldex CR 26 portion of Aldex OSM+ will remove those contaminants.

Hydrogen sulfide

The same chelation media used to oxidize metals in solution (i.e. Fe, Mn and As) is also able to oxidize and remove hydrogen sulfide. The Aldex CR 26 technical bulletin can be used to properly size a system as flow rate for this component varies indirectly with iron content. That is, the higher the influent iron level, the lower the service flow rate; see the bulletin for flow rate guidelines.

Organics, tannins and lignins

Multiple media are included in Aldex OSM+ to address the wide range of organics found in North American waters. Organics, tannins and lignans are difficult to remove but Aldex OSM+ is designed to accomplish this task. The primary resin used to remove organic color bodies from potable water is Aldex NSR, a macroporous, strong base type 1, styrenic-based resin which is very effective in the capture and removal of anions in solution. The NSR technical bulletin should be used to verify backwash expansion at a given gpm flow rate.

Regeneration

All resins are regenerated with a standard 10% brine solution.

Working media

All components have measurable ion exchange capacity making every component a “working media”.
