KDF®-85
Manufacturer: KDF Fluid Treatment, Inc
Categories: KDF Media, Iron / Manganese Removal, Hydrogen Sulfide
Specialty Media for Iron and Hydrogen Sulfide Removal
KDF®-85 is composed of high purity copper and zinc granules that can be used to remove dissolved iron and hydrogen sulfide (rotten egg odor) through a oxidation/reduction (redox) reaction.
Due to its heavy weight and relatively high service flow rate calacity per given quantity (up to 3 times more than alterantive media), KDF®-85 is frequently used as a relatively thin layer in a larger media bed containing other water filter media to add or improve enhance iron or hydrogen sulfide removal capacity. Bed depths rearely exceed 25 inches even in very large commercial backwashing systems and may be as little as an inch or 2 in the cartridge filter.
KDF 85 is also effective in controlling the buildup of bacteria, algae, fungi and scale, in filter beds making it ideal for use as an added layer in GAC beds, ion exchange resin beds, carbon block filters and inline carbon filters.
#8 garnet is recommended as the underbed material.
- Very high service flow rates for given filter surface area and media volume
- Concurrent treatment of iron and hydrogen sulfide (rotten egg odor)
- Effective over relatively wide pH range
- ANSI/NSF 61 validated
- Bacteriostatic
