1000 LPH RO Water Treatment Solution | Bottling/Hotels/Clinics

Q: Do I need UF pretreatment?

For feeds with SDI > 3, colloids/algae risk or frequent turbidity spikes, UF is recommended to stabilize flux and extend membrane life.

Q: What recovery should I expect at 1000 LPH?

Typical 55–70% for brackish feeds. Rule of thumb: TDS 500–1,500 ppm → 65–70%; TDS 1,500–3,000 ppm → 55–65%. Silica, temperature and SDI also impact the set-point.

Q: What energy do I plan for?

About 0.7–1.2 kWh per m³ at 8–16 bar, depending on salinity, temperature and recovery.

Q: What are the feed water limits?

Design targets: SDI ≤ 3, turbidity < 1 NTU, free chlorine < 0.1 mg/L (must be removed), iron < 0.05 mg/L, temperature 5–35 °C, operating pH 3–10.

Q: When is antiscalant/pH control required?

Whenever recovery or LSI indicates scaling risk. Typical antiscalant dose 2–5 ppm; pH adjustment may be used to control carbonate scaling.

Q: SS304 vs SS316L — how to choose?

Use SS316L for higher chloride exposure (coastal air/splash, disinfectant carry-over) or tighter hygiene; SS304 suits most indoor brackish installations.

Q: What membranes and configuration are used?

Typical 2 × 4040 polyamide elements for 1 m³/h. Final selection depends on feed TDS/temperature and required permeate.

Q: How often is CIP required and what triggers it?

Trigger on differential pressure rise (+15–20%), permeate conductivity drift, or normalized flux decline. Typical interval 3–6 months with proper pretreatment.

Q: What consumables/replacements should I expect?

5 μm cartridges: weekly–monthly (site-dependent). Antiscalant: continuous low-ppm dosing. RO membranes: 2–3 years typical life under good pretreatment.

1000 LPH RO Water Treatment Solution (≈1 m³/h)

Compact, reliable RO package for brackish/borewell water at small to mid-scale lines.

Permeate < 100 μS/cm
55–70% recovery
SDI ≤ 3 with UF/MMF
SS304/316L · PLC/HMI

Who is this for

Beverage & Food small packaging / ingredient water
Hotels/Hospitals/Clinics process/service water polishing
Electronics/Labs rinsing lines
Borewell/Brackish feed with seasonal turbidity/SDI spikes

Your challenges we solve

Feed TDS 800–3000 ppm, SDI > 3 → unstable flux & fouling
Conductivity & flow spikes at shift changes / variable loads
High CIP frequency due to insufficient pretreatment & scaling risk

Solution architecture

MMF / UF → 5 μm Cartridge → HP Pump (VFD) → RO → Permeate Tank → UV/Ozone (optional)

UF path keeps SDI ≤ 3 for membrane protection and stable flux.
Anti-scalant dosing enables higher recovery with controlled scaling.
PLC/HMI with trends & alarms (pressure, conductivity, flow).

Sizing & selection guide

Permeate target: < 100 μS/cm @ TDS ≤ 3000 ppm
Recovery: 55–70% (salinity, temperature, SDI dependent)
Energy: ≈ 0.7–1.2 kWh/m³ @ 8–16 bar
Membranes: typical 2 × 4040
Add UF when: SDI > 3 / colloids/algae risk

よくあるご質問

Do I need UF pretreatment?

For feeds with SDI > 3, colloids/algae risk or frequent turbidity spikes, UF is recommended to stabilize flux and extend membrane life.

What recovery should I expect at 1000 LPH?

Typical 55–70% for brackish feeds. As a rule of thumb:
• TDS 500–1,500 ppm → 65–70%
• TDS 1,500–3,000 ppm → 55–65%
Silica, temperature and SDI also impact the final set-point.

What energy do I plan for?

About 0.7–1.2 kWh/m³ at 8–16 bar, depending on salinity, temperature and recovery.

What permeate quality can I achieve?

With correct pretreatment and antiscalant dosing, < 100 μS/cm is typical for brackish feeds ≤ 3,000 ppm TDS.

What are the feed water limits?

SDI ≤ 3, turbidity < 1 NTU
Free chlorine < 0.1 mg/L (must be removed)
Iron < 0.05 mg/L
