For restaurant water, factory drinking-water supply and small-factory cleaning, with suitability checked against your source water and required quality.
Choose a starting capacity
Three standard models
QZ-RO250
250 L/h
Pretreatment + RO unit.
Connects to a mains-water supply, subject to an inlet-condition review.
QZ-RO500
500 L/h
Pretreatment + RO unit.
Connects to a mains-water supply, subject to an inlet-condition review.
QZ-RO1000
1,000 L/h
Raw-water pump + pretreatment + RO unit.
Supply scope: RO250 and RO500 exclude the raw-water pump. Water tanks and distribution pumps are not included with any of these three models.
Available controls: Tank-level start/stop, low-water or low-pressure shutdown protection, and automatic flushing. Confirm your required configuration with us.
Nominal capacity is not a guaranteed daily output. Feedwater, temperature, operating time, pretreatment and required water quality affect model suitability and actual production.

Allow additional space for pipework, access and maintenance; equipment dimensions are not the full installation footprint.
At nominal flow, eight operating hours gives a planning calculation of 2,000 / 4,000 / 8,000 litres respectively, not a guaranteed yield. Startup and maintenance also affect available operating time.

Built and assembled by Qingze
Our Dongguan team handles configuration, assembly, pipework, electrical wiring and pre-dispatch commissioning.
Video or on-site equipment viewings are available by appointment; the equipment, viewing content and timing are confirmed in advance.
Different water or process requirements?
Consider a custom system
Groundwater, larger demand, a different water-quality target or integration with existing equipment may need a project-specific configuration.
Industrial RO options →
RO + EDI and deionization options →
Single-pass RO, two-pass RO and RO + EDI are selected for the application and required quality, not flow alone.
Not sure which model fits?
Tell us what the water is for and your approximate demand. We can review the source water, required quality and site conditions together.
Selection guides and optional enquiry preparation
Daily volume, peak demand, operating hours and storage help determine capacity. If available, share your original water report, required point-of-use quality, country, space, power, incoming water and drainage. Tanks, transfer pumps, installation and commissioning are reviewed as separate scope items.
