KDF 85 Media Iron for the removal of heavy metals

KDF 85 — Filtration Media for Removal of Iron and Heavy Metals

⚙️ Effective solution for eliminating iron, hydrogen sulfide, and heavy metals from water

KDF 85 is a high-purity copper-zinc granulated filtration medium that uses a redox (oxidation-reduction) reaction to effectively remove dissolved iron, hydrogen sulfide, and heavy metals from water. It also inhibits the growth of bacteria, algae, and fungi.

✅ Applications:

✔️ Removal of iron and hydrogen sulfide in residential and industrial systems
✔️ Reduction of heavy metals like lead, mercury, nickel, and chromium
✔️ Pre-treatment before reverse osmosis and ion exchange systems
✔️ Suitable for private wells, municipal water, and commercial supply lines
✔️ Can be used with activated carbon to extend filter life

✅ Benefits:

✔️ Removes up to 99% of dissolved iron and hydrogen sulfide
✔️ Effectively reduces levels of heavy metals
✔️ Inhibits microbial growth without chemical agents
✔️ Extends the service life of downstream filters
✔️ 100% recyclable, chemical-free media

⚙️ Technical Specifications:

• ✔️ Form: granular

• ✔️ Composition: high-purity copper-zinc alloy

• ✔️ Particle size: 0.15–2.0 mm

⚙️ Usage Instructions:

1. Pre-rinse: Rinse with clean water to remove fines before use

2. Loading: Fill the filter tank with KDF 85, leaving 20% of freeboard for backwash expansion

3. Operation: Maintain recommended flow rate for optimal performance

4. Backwashing: Perform backwash when pressure drops or water quality decreases; use 1.5–2× flow rate for 10–15 min

5. Replacement: Replace media every 3–5 years depending on water quality and usage intensity
