Document type: product selection information. The illustrations on this page are AI-generated diagrams, not project photographs or specific models offered for supply.
For initial factory process-water enquiries and configuration comparisons. Bring feedwater, production tasks, storage, supply and acceptance conditions into a configuration document that can be checked.
What this information helps you discuss
For factory process water where dissolved-salt control needs consideration, and projects with explicit feedwater requirements from downstream equipment. Feedwater and intended use must jointly determine whether RO is appropriate and which pretreatment is needed.
This information helps compare suppliers’ quotations on a common basis. It describes an equipment category and does not replace the model documents for a specific, confirmed complete system.
Check the configuration by function
| Module | What to confirm for this order | Documents supplied with the order |
|---|---|---|
| Pretreatment and cartridge safety filtration | Actual treatment task, filtration rating, materials and maintenance conditions | Models, quantities and instructions |
| RO system | Net water production task, design conditions, membrane elements and layout | Configuration list, operating conditions and manufacturer references |
| Control and measurement | Measuring points for flow, pressure and conductivity, and protective logic | Instrument list, measuring-point descriptions and operating documents |
| Storage and supply | Usable storage, end-use peaks, supply pumps and controls | Capacity range, supply requirements and boundaries |
| Site provisions | Power, drainage, foundations, maintenance and access conditions | Site coordination and responsibility list |
Parameters need conditions and units
| Parameter | Suggested units or notation | Status of supply documentation for this order |
|---|---|---|
| Net water output | m³/h, with feedwater, temperature and agreed conditions stated | To be confirmed against the corresponding configuration |
| Water-use task | m³/d, hourly peak in m³/h, duration in minutes | To be provided and checked by the purchaser |
| Pressure and recovery | State pressure in bar or MPa; specify system boundaries for recovery | To be confirmed by design and corresponding equipment documents |
| Water-quality acceptance | Measures, sampling points, instruments or test methods, and sampling conditions | To be agreed in writing for the downstream use |
| Membranes and components | Complete brands and models, quantities and source-document revisions | Verify before supply |
| Power, connections and dimensions | List according to specific equipment drawings and manuals | Verify before supply |
RO permeate output depends on operating conditions.[R1] Quotations should therefore state both quantity and conditions. A prominent tonnage figure alone is insufficient, and membrane-element factory test values cannot replace complete-system acceptance.
Confirm quotation scope item by item
List equipment and initial consumables, transport and unloading, installation and commissioning, sampling and testing, training, and spares separately. Confirm lead time, quotation validity and site coordination conditions together.
At delivery, hand over equipment documents, operation and maintenance instructions, initial operating records and service contacts together. Quality criteria, service response and fees must be established in the written documents for this order.
Frequently asked questions
Can this information serve directly as a fixed model specification or quotation?
No. It is a purchasing checklist. The actual model, configuration, scope of supply, price and validity must be confirmed in the quotation for this order.
Why check storage and pump sets separately from the RO system?
System production may not coincide with peak demand at points of use. Storage, usable levels and supply pumps together determine supply arrangements and should be specified separately.
What should be agreed before acceptance?
First agree feedwater and operating conditions, acceptance measuring points, methods and pass criteria. Then relate these to output, water quality and supply requirements so that everyone uses the same basis.
