Custom project experience
Qingze water-treatment project in Senegal
Qingze Systems supplied a two-pass RO system for the expansion of a bottled-water and beverage business in Senegal. This was a custom system with second-pass permeate output of 6 m³/h, separate from the QZ-RO500 standard model on this page.
How this custom project handled source-water constraints
The first RO pass produced 9 m³/h and fed the second pass, which produced 6 m³/h. These are stages in series, so the two outputs are not added together. The project’s deep-well source water had conductivity of 1,300 µS/cm and hardness of 178 mg/L.
When the customer reported insufficient well-water supply, a separate RO concentrate-recovery unit was added. Recovered permeate returned to the raw-water tank, mixed with groundwater and went through the main treatment system again. It was not supplied directly to beverage production.
For your project, equipment selection should consider source-water quality, daily demand, supply limitations and site connections. Recovery conditions must be assessed for the specific water and system.

Single-pass RO for aluminium processing
Our Senegal aluminium-factory project used pretreatment and a 2 m³/h single-pass RO system, with installation carried out by the customer and guidance from Qingze. This is a separate custom project, not the QZ-RO500 model or its supply scope.

Compare RO500 and RO1000 configurations
Compare 500 L/h and 1000 L/h RO systems
Compare the nominal output, equipment footprint and supplied equipment alongside your daily consumption and available operating hours.
QZ-RO500 · 500 L/h
- Equipment dimensions: 900 × 600 × 1600 mm
- Specified equipment power: 1.1 kW
- Standard supply: pretreatment and RO main unit
- Raw-water pump, storage tanks and distribution pump are not included
QZ-RO1000 · 1000 L/h
- Equipment dimensions: 1000 × 600 × 1600 mm
- Specified equipment power: 1.5 kW
- Standard supply: raw-water pump, pretreatment and RO main unit
- Storage tanks and distribution pump are not included
Nominal capacity alone does not determine suitability. Share source-water quality, peak demand, operating hours and required final-water quality so the complete configuration can be reviewed.
For a larger capacity or different treatment process, review standard and custom industrial RO options.

Three questions before selecting 500 L/h
How much water do you need?
Share daily consumption, operating hours and peak demand. For planning only, 500 L/h over eight operating hours gives 4,000 litres before allowing for real operating conditions and downtime.
What water quality does production require?
State the application and required final-water specification. If available, send a recent source-water analysis. Equipment suitability must be assessed for your process.
Is the site ready?
- Check incoming voltage, phase and frequency.
- Check the incoming water supply and pressure.
- Plan permeate storage, distribution and concentrate drainage.
- Allow room to move the equipment into position and service it.
No fixed recovery rate, final-water quality or operating cost is assumed without reviewing your conditions.
What water-analysis report should you send for an RO quotation?
Water-report details and a project brief
Share the full laboratory report, sampling date, sampling point and units. Include the source-water temperature range where known. Useful measurements include pH, conductivity or TDS, hardness, alkalinity, iron, manganese, silica, turbidity and free chlorine. Keep the report’s units intact; hardness may be reported as CaCO3. A handheld TDS reading alone does not describe all constituents needed for a design review.
Keep source water and final-water requirements separate
Tell us whether the sample is mains water, well water, tank water or water after existing treatment. Describe where the treated water will be used and provide your production-water specification separately.
Prepare a short project brief
- Country and production application
- Water source and available analysis report
- Required water quality at the point of use
- Daily consumption, peak demand and operating hours
- Available voltage, phase, frequency and inlet pressure
- Existing storage, distribution equipment and installation space
If a report is not yet available, start with the information you have. We can review it and discuss what else is needed before confirming the configuration. Send report files by email or WhatsApp and include a short summary in the online enquiry.
