Water‑treatment System (25 m³/h Single‑pass RO for 24 000 BPH 750 ml bottled‑water line)
‑ Design boundary: Raw‑water inlet to filling‑pump outlet.
‑ System piping & equipment comply with European NSF and Danone POSEIDON specification plus national mineral‑water standards. CIP cleaning system capacity 4 m³/h for periodic pipeline & equipment washing.
‑ If source water is well‑ground‑water, well‑protection facilities are recommended.
‑ Separated process routes for product water and rinsing water.
‑ Scope: Raw‑water pretreatment, RO reverse‑osmosis section, CIP cleaning section, ozone sterilization section, finished‑water supply section, PLC control section.
A. Raw‑water Pretreatment
‑ Booster pump, multimedia (quartz‑sand) filter, activated‑carbon filter, 5 μm precision filter, 1 μm precision filter.
‑ Quartz‑sand filter removes suspended solids, colloids and coarse particles.
‑ Activated‑carbon filter removes residual chlorine, organics, partial heavy‑metals and odours to improve taste.
‑ Precision filter removes particles ≥ 1 μm.
B. RO Reverse‑Osmosis Unit
‑ Advanced energy‑saving membrane‑separation technology for substance separation under pressure higher than osmotic pressure.
C. CIP Cleaning Unit
‑ Periodic chemical cleaning to remove accumulated contaminants on filter media & membranes.
D. Ozone‑sterilization Unit
‑ Eliminates micro‑organisms and bacteria.
E. Control Section
‑ PLC‑automated operation of whole water‑treatment plant.
