Water treatment resources
Plan your RO equipment enquiry
Practical guides for gathering water information, comparing treatment options and agreeing equipment and site responsibilities.
Use these resources to prepare a project brief for your own application. Equipment selection still needs a review of your source water, required quality, production demand and site conditions.
Before requesting a quotation
Using well water? Start by reviewing the source, existing pretreatment and the selected RO unit’s feed conditions.
Can well water feed an RO system directly? →
For a closer review, see why TDS alone is not enough to select RO and hard water and RO scaling risk.
1 · Feedwater
Water-analysis information
Prepare the original report, source, sampling details and units. Identify what is known and what still needs confirmation.
2 · Treatment route
Single-pass RO, two-pass RO or RO + EDI
Review treatment options against the production use and required water quality, with examples from actual projects.
3 · Supply boundaries
Equipment and site scope
Prepare a clear supply list and identify incoming water, power, pipework, installation and support responsibilities.
Planning by application
Prepare requirements for your production process
Food and beverage RO procurement checklist: eight points to confirm →
Start with the production use and the quality required at the use point. These guides help you gather the water, demand and site information needed for a system review.
Food production
Review ingredient and production water, operating shifts, peak demand, storage and transfer.
Electronics high-purity water
Define quality at the use point and review the treatment route, storage and distribution.
Factory groundwater
Prepare representative source analysis and describe variations before reviewing pretreatment and RO requirements.
Before shipment
Prepare your factory for RO installation
Check feedwater, electricity, drainage, access, pipe connections, storage and site personnel before equipment is shipped.
Use the RO500 example and a reusable site brief to discuss your conditions with the supplier and installation team.
Agree which equipment, site connections, documents and installation or commissioning support are included.
Existing systems
Replacement or upgrade?
RO operation and maintenance planning: records, spares and support responsibilities →
RO concentrate recovery for a beverage factory: supply, return route and enquiry checklist →
Separate an operating problem from a new capacity requirement. Gather the existing treatment route, operating and maintenance records, equipment photographs and available downtime.
Consumable replacement, a pretreatment upgrade and complete-system replacement have different supply boundaries. Identify the equipment you want to retain.
Standard equipment
Choose capacity and compare the equipment scope
Match daily demand, peak use, operating hours and usable storage before selecting a nominal flow.
Read the 250, 500 and 1000 L/h selection guide →
Enter daily use and available RO operating hours to compare nominal capacities and copy a brief for your enquiry.
Estimate daily output and plan storage for a 500 L/h RO system →
When should you review a custom RO system? →
Review nominal capacity, dimensions and the confirmed supply scope for QZ-RO250, QZ-RO500 and QZ-RO1000.
Standard RO model comparison →
Download the RO500 / RO1000 selection sheet (PDF) →
Prepare a project brief with your team
Use the four-sheet English workbook to record water demand, source-water information, site conditions and supply responsibilities. Mark unknown items as “To be confirmed”.
Download the RO project brief (Excel)
XLSX · 4 worksheets · 31 KB. Complete the blue cells and send the file by email when ready to discuss your project.
Confirm feedwater and destination electrical conditions before selecting equipment.
Actual projects to review
These records describe different applications and equipment scopes. Project requirements and customer feedback should not be treated as a performance guarantee for another site.
