Guia de seleção de acessórios para tratamento de água
- 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
- Conformidade: required certificates (material/pressure/NSF/CE), document bundle
- Utilities: power spec, ambient constraints
- Replacement strategy: target change-out ΔP / UV lamp hours / resin capacity
Tip — Use the left CTA to send a water report and P&ID/photos; we reply within 24h with sizing and alternates.
- Escolha rápida: 4040 for ≤2–3 m³/h and compact skids; 8040 for ≥4 m³/h mains; UF upstream for high turbidity/organics.
- Passos:
- 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).
- Compatibility checklist: 4040 vs 8040, spacer thickness/pressure drop when mixing brands, backpressure limits.
- Common pitfalls: no dechlorination; high recovery with poor SDI; ignoring temperature correction for flux.
| Type | Typical target | Notes |
|---|---|---|
| RO | 95–99.5% salt rejection | Recovery 45–75% with antiscalant strategy |
| NF | Hardness/organics selective retention | Lower pressure; partial divalent retention |
| UF | Turbidity/colloids/macromolecules | Improve SDI to ≤3–4 for RO |
| Sistema | Capacidade por comboio | Recuperação | Energia (tip.) | Saída |
|---|---|---|---|---|
| RO salobra | 1-60 m³/h | 65-85% | 0,7-1,5 kWh/m³ | 10-200 µS/cm |
| Água do mar RO | 1-50 m³/h | 35-50% | 3,5-5,0 kWh/m³ | 300-700 µS/cm |
| Pré-tratamento UF | 1-100 m³/h | - | - | SDI ≤ 3 @15 min |
| Polimento EDI | 0,5-30 m³/h | - | - | ≤ 0,5 µS/cm |
- Escolha rápida: Corrosive/high-temp → SS316L; standard desalination → FRP (lightweight, corrosion-proof).
- Passos:
- Entry type: end vs side—match skid piping orientation.
- Pressure class: brackish 300–450 psi; seawater/high-pressure 600–1000+ psi.
- Ligações: NPT/BSP/flange; brackets/clamps; end-cap style and O-ring spec.
- Checklist: element length & count, vent/drain ports, hygienic vs industrial grade.
- Armadilhas: no allowance for insulation/thermal expansion; wrong port orientation; no pull-out space for elements.
| Spec | Typical |
|---|---|
| 4040 | 1 element/vessel; ≤25 bar |
| 8040 | 1–7 elements/vessel; ≤41 bar (brackish) |
- Escolha rápida: Pre-RO: 5–20 µm; polishing: 1–5 µm; absolute-rated for critical steps.
- Passos:
- 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.
- Checklist: housing length/guide, gasket (EPDM/Viton/PTFE), sanitation method (thermal/chemical).
- Armadilhas: over-fine rating → frequent clogging; no staged filtration; wrong basket for bag filters.
| Micron | Use case |
|---|---|
| 20–50 µm | Coarse protection after sand filter |
| 5–10 µm | Typical RO pre-filter |
| 1–5 µm | Polishing / sensitive steps |
- Escolha rápida: FRP for most corrosive/ambient duties; steel for high temp/pressure and large flanged nozzles.
- 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.
- Softeners:
- Resin volume = treated load ÷ working capacity; regeneration by time/flow.
- Common salt dose: 6–10 lb/ft³ balancing efficiency and leakage.
- Armadilhas: insufficient backwash → bed fouling; wrong liner/coating in steel; undersized control valve.
- Escolha rápida: Small flow/chemical duty → solenoid diaphragm; higher flow/backpressure → mechanical diaphragm.
- 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).
- Checklist: backpressure (bar), stroke range, wetted materials (PTFE/EPDM/FKM), anti-siphon/back-pressure valves, pulsation dampener.
- Armadilhas: low backpressure → siphoning/overfeed; viscosity change with temp/concentration ignored.
- Escolha rápida: Post-RO polishing: 30–40 mJ/cm² (higher for critical applications).
- Passos:
- 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.
- Armadilhas: ignoring UVT swings; no bypass for maintenance; no lamp-life tracking.
- Escolha rápida: Manual vs automatic (time/flow/ΔP triggers) per process criticality.
- Checklist: thread standard (NPT/BSP) or flange, seal materials (EPDM/FKM/PTFE), Cv/pressure drop, temp/pressure rating.
- Armadilhas: thread standard mismatch; incompatible elastomers; undersized regeneration flow.
