Set the function and connection point
DAF precontact differs from a biological-reactor sidestream or ozone contact tank. State the objective: chemical dose, aeration, gas contact or cleaning. Draw take-off, return, bypass, mixing and available space.
The stated GENESIS™ range is 1–100 m³/h by configuration. That figure is not automatically plant flow or transfer performance. In a sidestream, recirculated fraction, contact time and mixing with the main flow matter.
- Average/maximum plant flow and available generator-loop flow.
- Proposed gas, source, purity, flow, pressure and compatibility risks.
- Water inlet/outlet pressure and return-point backpressure.
Check the water and every utility
Abrasive solids, particle size, viscosity, oil, pH, salinity and temperature may dictate upstream protection and materials. Gas supply needs regulation, metering and interlocks defined for the model. Ozone requires whole-system design for contact, off-gas, ventilation and safety.
No motor in the generation core does not mean zero energy. Count pumps, gas production or compression, controls and, where applicable, off-gas treatment.
| Design input | Decision it supports |
|---|---|
| P&ID and pressures | Connection and gas–liquid margin |
| Water and particles | Protection and materials |
| Objective and baseline | Trial metric |
| Utilities | Whole-system energy and operation |
Validate before promising performance
Define acceptance against the process: outlet quality and chemicals in DAF, DO/energy/effluent in biological treatment, or ozone utilisation and residual gas where relevant. Compare with a baseline and meter auxiliaries. The supplier must provide model-approved limits and sequences; a conceptual diagram is not an operation manual.
For early sizing, prepare two drawings: the normal process path and the proposed sidestream or inline arrangement. Mark isolation and bypass, water and gas meters, pressure points and sampling ports. This lets the supplier identify missing utilities before promising a model or performance level.
Common questions
Can a 10 m³/h unit only serve a 10 m³/h plant?
Not necessarily. A sidestream can treat and return a fraction; the outcome depends on recirculation, mixing and measured objective.
