Industrial pretreatment where oil, grease, light solids, fibers, or floatable flocs must be separated
Industrial water treatment · Project-specific configuration
Dissolved Air Flotation (DAF) Systems
A project-specific dissolved-air-flotation package for separating conditioned flocs, oil, grease, light solids, and other floatable material before the next treatment stage.
Direct answer: Baihuipu configures dissolved air flotation systems for industrial wastewater streams where free or dispersed oil, grease, light suspended solids, or chemically conditioned flocs need to be separated before downstream treatment. Final suitability depends on representative wastewater behavior, treatment chemistry, hydraulic conditions, and the required solids-handling route.
Configuration starts with water data, the treatment target, and site conditions.

When This System Should Be Evaluated.
Use these application boundaries as a screening guide. Final suitability still requires representative water data and an agreed treatment objective.
Food and beverage, metal finishing, chemical, textile, and similar wastewater streams after a project-specific review
Load reduction ahead of biological treatment, membranes, reuse polishing, or a discharge-control process
Projects that can define the wastewater source, flow variation, conditioning chemistry, and float-sludge route
System value
A Separation Stage Built Around Particle Behavior.
The DAF package, conditioning sequence, and solids route are configured around what can be floated from the actual wastewater and what the downstream process needs.
Focused separation role
Address floatable or conditioned material before downstream biological, membrane, reuse, or discharge-control stages.
Integrated process scope
Coordinate feed equalization, chemistry, air recycle, skimming, and solids handling around the same hydraulic design.
Evidence-led selection
Use representative samples and treatment objectives to avoid treating generic removal claims as project guarantees.
Selection basis
What Defines the Right Configuration.
Capacity, materials, utilities, automation, and guaranteed performance are confirmed against these project inputs—not assumed from a generic model.
| Decision input | What the technical review needs |
|---|---|
| Wastewater behavior | Source streams, oil and grease condition, suspended-solids characteristics, temperature, pH, surfactants, and expected variation |
| Flow and loading basis | Average, peak, batch flow, operating schedule, and any upstream tank or discharge pattern |
| Treatability evidence | Representative samples, available jar-test or flotation observations, proposed chemical program, and the target separation role |
| Downstream and residual route | Required clarified-water quality, downstream process, float-sludge storage or dewatering, utilities, footprint, and supply boundaries |
Typical treatment route
From Wastewater Review to a Clear Flotation Scope.
A reliable DAF evaluation begins with the wastewater, then defines chemistry, separation, residuals, and the next treatment stage.
Wastewater review
Identify source streams, oil and solids behavior, surfactants, pH, temperature, and flow variation.
Conditioning review
Screen pH control, coagulation, flocculation, or other conditioning only where the wastewater supports them.
Flotation separation
Define recycle, air dissolution, contact, flotation, skimming, and clarified-water transfer around the required duty.
Residuals and downstream route
Coordinate float-sludge handling and the next treatment, reuse, or discharge-control stage.
Relevant project context
What Should Be Confirmed Before a DAF Proposal.
These scope boundaries help buyers prepare a meaningful DAF inquiry. They are not universal performance guarantees.
Dissolved-air-flotation units
Dissolved-air-flotation units are included in Baihuipu's documented industrial wastewater equipment scope.
Wastewater behavior and treatment chemistry
A bench review can screen conditioning chemistry, but final flotation performance, hydraulics, and solids handling require a project-specific proposal.
Capacity, removal, and outlet requirements
Capacity and treated-water performance are not fixed catalogue values; they are defined against the confirmed water, target, and contractual scope.

Buyer FAQ
Questions to Resolve Before Selection.
These answers define the decision process without turning project-specific values into universal specifications.
What does a DAF system remove?
A DAF system is commonly evaluated for floatable or conditioned material such as oil droplets, grease, light suspended solids, fibers, and flocs. It is not a universal treatment for dissolved salts, all dissolved COD, ammonia, or every stable emulsion.
Does every DAF system need chemical conditioning?
Not necessarily, but many industrial applications require pH control, coagulant, polymer, or another conditioning approach to create separable flocs. The requirement should be based on representative wastewater and testing.
Can DAF replace biological treatment?
Usually no. DAF is a separation stage. When biodegradable dissolved organics, ammonia, or other dissolved contaminants remain, a downstream biological, oxidation, adsorption, membrane, or other appropriate stage may still be required.
What is needed before requesting a DAF quotation?
Provide wastewater analysis, source-stream information, flow profile, treatment target, existing test observations, site constraints, utilities, solids route, and the desired supply boundary.
Are removal rates and capacity fixed for all DAF systems?
No. They depend on wastewater chemistry, particle behavior, conditioning, hydraulic loading, temperature, equipment arrangement, and the agreed design basis.
