  • Parasites (Giardia, Cryptosporidium)
  • Fungi
  • Algae
  • Protozoa

6. Radioactive Contaminants

  • Uranium (U)
  • Radon (Rn)
  • Radium (Ra)
  • Plutonium (Pu)

  • Cesium-137

7. Pharmaceutical & Hormonal Contaminants

  • Antibiotics
  • Hormones (Estrogen, Testosterone, etc.)
  • Painkillers (Ibuprofen, Acetaminophen)
  • Antidepressants
  • Steroids
  • Caffeine
  • Nicotine

8. Dissolved Gases & Odor-Causing Compounds

  • Hydrogen sulfide (H₂S) – “Rotten egg” smell
  • Carbon dioxide (CO₂)
  • Methane (CH₄)
  • Chlorine byproducts

Final Water Purity

ZRO reverse osmosis systems typically removes 95-99% of contaminants, producing clean, purified, and better-tasting water while reducing Total Dissolved Solids (TDS) to a very low level.
