Reference data for project discussion. Final dimensions, power, weights and design duty are confirmed in the project technical proposal. Installed power is not a statement of operating energy consumption.
Design flow is confirmed for the project. Please share your required average and peak flow, with the units and daily operating hours.
02 / TREATMENT ROUTE
A typical configuration.
- 01Chemical flocculation
- 02Saturated water generation
- 03Bubble–particle attachment
- 04Froth separation
- 05Scum discharge & clarified water
The listed influent envelope is for the standalone duty described in the supplied data. When integrated into a treatment train, influent depends on the upstream stage. Actual process configuration, unit selection and equipment specifications are confirmed for each project.
03 / DESIGN BASIS
Define the influent.
Agree the target.
The listed influent envelope is for the standalone duty described in the supplied data. When integrated into a treatment train, influent depends on the upstream stage.
Discharge or reuse limits, acceptance methods and operating conditions are reviewed and agreed for each project.
| Parameter | Reference influent envelope |
|---|---|
| CODcr | ≤ 600 mg/L |
| BOD₅ | ≤ 200 mg/L |
| Suspended solids | ≤ 400 mg/L |
| Oil | ≤ 50 mg/L |

05 / QUESTIONS
Before you specify.
How is the equipment selected for my project?
Send the wastewater source, average and peak flow, water analysis and treatment target. The process and equipment scope are confirmed after review of these conditions.
Does a DAF unit provide complete wastewater treatment?
A DAF unit provides solid–liquid separation. Additional treatment may be needed for dissolved pollutants and the final discharge or reuse target.
Can I specify component brands?
Component brands are selected for each project. Client-specified brands can be accommodated on request, with final makes and models confirmed in the technical proposal.
Which control options are available?
PLC and touchscreen control can be provided. Remote monitoring, mobile alerts and an English operator interface are available as options.
Can you provide English documents and project support?
English operating manuals, electrical drawings and process flow diagrams can be provided. Remote installation guidance, on-site installation and commissioning, and operator training can be arranged. Scope and fees are agreed per project.
Final process selection, equipment specifications and performance commitments are subject to the confirmed influent conditions, treatment targets and agreed scope of supply.
