2) Who Is It For & Typical Use Cases

• Beverage & food: ingredient/blend water, boiler feed makeup.
• Pharma pre-treatment: PW/HPW upstream of storage tanks and loops.
• Electronics/general manufacturing: rinse/process water at stable conductivity.
• Facilities/utilities: small industrial plants requiring 1 m³/h continuous permeate.

Pair the system with a permeate buffer tank for stable operations: Aseptic stainless steel water tanks.

4) Recovery vs Feed TDS (Start Here)

Pick an initial recovery and design pressure from the table below. Verify with your membrane supplier’s software using real water analysis (TDS, hardness, alkalinity, silica, iron/manganese, temperature).

Feed TDS (ppm)	Recommended Recovery	Design Pressure (bar)	Catatan
~500	65-70%	8–10	Antiscalant usually sufficient; monitor SDI
~1,000	60–65%	10–12	Consider softener if hardness is high
~1,500	55–60%	12–14	Antiscalant + careful recovery control
~2,000	50–55%	14–16	Higher scaling risk; check silica/alkalinity

5) Pretreatment & Water Chemistry

• SDI < 5 at the RO inlet; backwashable filtration or UF upstream if colloids are persistent.
• Free chlorine < 0.1 ppm (use activated carbon or sodium metabisulfite as appropriate).
• Hardness/alkalinity/silica: choose between softener vs antiscalant based on water analysis.
• Iron/manganese: remove to trace levels to avoid fouling and membrane oxidation risks.

Choose BWRO elements from our membrane category: RO membranes (4040/8040) — e.g. ULP31-4040.

6) 1000 LPH RO system Sizing & Selection Workflow

1. Define target conductivity and operating hours; add a permeate buffer tank if the draw is intermittent.
2. Correct for temperature via TCF. Lower temperatures reduce flux—consider margin in winter.
3. Select elements (4040 BWRO) and calculate flux: Permeate ≈ Σ(Area × flux × TCF). Keep transmembrane pressure within envelope.
4. Pick recovery from the table above; validate with scaling indices and supplier software.
5. Choose Configuration:
   • Config A (lower CAPEX): 2×4040, antiscalant dosing, recovery 55–65%.
   • Config B (higher recovery): 2×4040 + optimized antiscalant program, recovery up to ~70% at low TDS.

7) Electrical, Piping & Utilities

• Power: 380–415 V, 50–60 Hz, ~2.2–3 kW HP pump; allow for start current per motor spec.
• Koneksi: feed, permeate, concentrate, CIP ports; provide suitable drain for flushing/CIP.
• Footprint: ~1.2×0.8 m frame, ~1.6 m height; ensure handling/clearance and noise considerations.
• Permeate tank: size for buffer; include venting and level control. See aseptic tank options.

8) P&ID and Bill of Materials (BOM)

Core components: HP pump, 4040 elements & vessels, 5 µm cartridge housing, pressure gauges/transmitters, flow meters, conductivity sensors, valves & control cabinet (PLC/HMI).

9) Commissioning & Acceptance (How-To)

Step	What to check	Pass criteria
Pre-start	Wiring/rotations, leaks, valve positions, SDI & residual chlorine	SDI <5; Cl₂ <0.1 ppm
Flush	Initial rinse to drain until stable conductivity	Conductivity trend stable

Record baseline	Permeate LPH, conductivity, feed/perm/concentrate pressures, pump amps	≥1000 LPH at designed pressure & quality
Acceptance	Noise/vibration, leaks, interlocks/alarms	No leaks, safe shutdowns OK

10) Operation, Maintenance & CIP

Daily/Weekly/Monthly Tasks

Cadence	Task	Owner	Record

CIP Triggers & Hints

• Rapid flux drop or permeate conductivity spike; rising pressure differential.
• Apply appropriate recipes (alkaline/acid/biological) within membrane compatibility limits.
• Post-CIP: verify recovery, pressure and quality within baseline ± tolerance.

11) Options & Upgrade Paths

• Double-pass RO for ultra-low conductivity or boron/silica constraints.
• EDI after RO for continuous deionization (ultra-pure applications).
• Remote monitoring, OPEX dashboard, energy-efficient pumps/inverters.

12) Cost & Lead Time Drivers

• Membrane brand/quantity, pretreatment selection (softener/UF/carbon/antiscalant).
• Automation level, electrical standard, frame material, documentation scope.
• Shipping and handling (crating, lifting, access); site utilities and installation support.

15) FAQs

What is the typical recovery of a 1000 LPH RO system at ~1,000 ppm TDS?

Start around 60–65% and validate with scaling indices and supplier software. Higher TDS typically lowers recovery.

Do I need a softener or can I use antiscalant only?

Base it on hardness/alkalinity/silica. Many sites dose antiscalant effectively up to ~1,500 ppm TDS; high hardness may justify a softener.

What is the power consumption?

Expect ~2.2–3 kW HP pump power at nominal conditions; verify actual amps and voltage on site.

What are SDI and residual chlorine limits?

SDI < 5 at RO inlet and free chlorine < 0.1 ppm. Use carbon or sodium metabisulfite when needed.

Can the system run 24/7 and how often should membranes be cleaned?

Yes. Run CIP based on flux decline/∆P/conductivity trends. Many sites clean quarterly or as needed.

What footprint and utilities are required?

Approx. frame 1.2×0.8 m, height ~1.6 m; 380–415 V three-phase; drain for flush/CIP; clearances for service.

How do I pair the unit with a permeate tank or EDI?

Use a sealed tank with level control and venting; EDI downstream when ultra-low conductivity is required.
