Guide de sélection des accessoires de traitement de l'eau

  • Flow & duty: average/peak flow (m³/h), run hours, single/parallel lines
  • Water data: TDS, SDI/turbidity, temperature, pH, key ions/metals, UVT (for UV)
  • Mechanical: piping size & standard (NPT/BSP/flange), layout, available footprint
  • Conformité : required certificates (material/pressure/NSF/CE), document bundle
  • Utilities: power spec, ambient constraints
  • Replacement strategy: target change-out ΔP / UV lamp hours / resin capacity

  1. Choix rapide : 4040 for ≤2–3 m³/h and compact skids; 8040 for ≥4 m³/h mains; UF upstream for high turbidity/organics.
  2. Les étapes :
    • Set targets (rejection/retention, permeate flow, recovery) and feed limits (SDI≤5, temp, residual chlorine=0).
    • Decide elements per vessel & stages (typical per-element flux depends on temp/fouling).
    • Check TMP, end-of-run ΔP, and CIP chemistry compatibility (keep 10–20% margin).
  3. Compatibility checklist: 4040 vs 8040, spacer thickness/pressure drop when mixing brands, backpressure limits.
  4. Common pitfalls: no dechlorination; high recovery with poor SDI; ignoring temperature correction for flux.

  1. Choix rapide : Corrosive/high-temp → SS316L; standard desalination → FRP (lightweight, corrosion-proof).
  2. Les étapes :
    • Entry type: end vs side—match skid piping orientation.
    • Pressure class: brackish 300–450 psi; seawater/high-pressure 600–1000+ psi.
    • Connexions : NPT/BSP/flange; brackets/clamps; end-cap style and O-ring spec.
  3. Checklist: element length & count, vent/drain ports, hygienic vs industrial grade.
  4. Les pièges : no allowance for insulation/thermal expansion; wrong port orientation; no pull-out space for elements.
SpecTypical
40401 element/vessel; ≤25 bar
80401–7 elements/vessel; ≤41 bar (brackish)
  1. Choix rapide : Pre-RO: 5–20 µm; polishing: 1–5 µm; absolute-rated for critical steps.
  2. Les étapes :
    • Size & caps: 10/20/30/40″, DOE/SOE (222/226); media PP/PES/PTFE per chemistry.
    • Efficiency: Absolute (β≥5000) vs nominal; match particle target & downstream sensitivity.
    • Flow/ΔP: rough rule 10″ 5–20 L/min; change-out ΔP 0.8–1.5 bar.
  3. Checklist: housing length/guide, gasket (EPDM/Viton/PTFE), sanitation method (thermal/chemical).
  4. Les pièges : over-fine rating → frequent clogging; no staged filtration; wrong basket for bag filters.
MicronUse case
20–50 µmCoarse protection after sand filter
5–10 µmTypical RO pre-filter
1–5 µmPolishing / sensitive steps
  1. Choix rapide : FRP for most corrosive/ambient duties; steel for high temp/pressure and large flanged nozzles.
  2. Media filters:
    • Surface loading (filtration rate): 5–10 m³/h·m² depending on water quality.
    • Backwash intensity: sand 12–18 L/m²·s, GAC 8–15 L/m²·s (30–40% bed expansion).
    • Fittings: top vs side mount, laterals/distributors, sight-glass/drain/manway.
  3. Softeners:
    • Resin volume = treated load ÷ working capacity; regeneration by time/flow.
    • Common salt dose: 6–10 lb/ft³ balancing efficiency and leakage.
  4. Les pièges : insufficient backwash → bed fouling; wrong liner/coating in steel; undersized control valve.
  1. Choix rapide : Small flow/chemical duty → solenoid diaphragm; higher flow/backpressure → mechanical diaphragm.
  2. Quick formula:
    Required flow (L/h) = Target dose (mg/L) × Water flow (m³/h) ÷ Solution concentration (%)

    Example: 3 mg/L NaOCl, 10 m³/h, 10% solution ⇒ 3×10 ÷ 10 = 3 L/h (×1.2 safety margin).

  3. Checklist: backpressure (bar), stroke range, wetted materials (PTFE/EPDM/FKM), anti-siphon/back-pressure valves, pulsation dampener.
  4. Les pièges : low backpressure → siphoning/overfeed; viscosity change with temp/concentration ignored.
  1. Choix rapide : Post-RO polishing: 30–40 mJ/cm² (higher for critical applications).
  2. Les étapes :
    • Confirm UVT @254 nm and dose setpoint.
    • Select chamber (stainless steel), sensors/alarms, and validation method.
    • Prefilter to ≤5 µm; plan sleeve cleaning and lamp change intervals.
  3. Les pièges : ignoring UVT swings; no bypass for maintenance; no lamp-life tracking.
  1. Choix rapide : Manual vs automatic (time/flow/ΔP triggers) per process criticality.
  2. Checklist: thread standard (NPT/BSP) or flange, seal materials (EPDM/FKM/PTFE), Cv/pressure drop, temp/pressure rating.
  3. Les pièges : thread standard mismatch; incompatible elastomers; undersized regeneration flow.
