A professional mineral water production line must include several critical stages: Raw Water Pre-treatment (Quartz sand filter, Activated carbon filter, and Sodium ion exchanger), Precision Filtration (Security filter), Core Purification (Ultrafiltration or Reverse Osmosis systems), and Sterilization (Ozone generator and UV sterilizer). For mineral water specifically, Ultrafiltration (UF) is often preferred over Reverse Osmosis because it removes bacteria and suspended solids while retaining beneficial natural minerals.
