PRODUCT DESCRIPTION & TECHNICAL DOCUMENTS

How dissolved air flotation (daf) fits your process.

Operating principle

Flotation treatment for suitable suspended solids, fats and floatable contaminants.

Fine air bubbles attach to suitable suspended material and float it to the surface. Coagulation and flocculation may be required based on treatability tests.

Engineering checks

  • Jar / flotation test results
  • Solids load and required separation area
  • Recycle flow and air-release conditions
  • Float-handling and chemical requirements

Configuration & equipment

  1. Conditioned feed inlet
  2. Recycle pressurization pump
  3. Air-dissolution / saturation system
  4. Flotation separation tank
  5. Float collection mechanism
  6. Clarified outlet and sludge discharge

Configuration options are reviewed against the project duty. Supply quantities and final scope are defined in the approved proposal.

Process / operating itemEngineering requirement
Process review 1A pressurized recycle stream introduces dissolved air into the flotation zone.
Process review 2Float removal and bottom-solids withdrawal are defined in detailed design.
Operating and maintenanceInspect air release and recycle pressure. Clean float collection equipment. Trend treated-water quality and float consistency.
DocumentationProject-specific datasheet, PFD, P&ID, equipment GA, electrical load list and O&M documentation as agreed.

CONSTRUCTION OPTIONS

Modular fabrication or civil construction?

Select the treatment process first. Then choose a construction method that fits the site, transport access, project schedule and future expansion.

Prefabricated modular plant

Factory-fabricated process modules connect to agreed site tanks and utilities. Review transport dimensions, lifting access, corrosion protection and maintenance clearances.

For a packaged MBBR example, the anoxic and aerobic compartments have flat floors; a downstream tube-settler compartment can use a sludge hopper. Equalization and treated-water storage may be separate civil tanks.

Civil construction plant

Site-built basins provide a project-specific layout. Process design must coordinate with soil conditions, groundwater, structural design, hydraulic levels and access for operation.

RCC construction can support several treatment technologies. Civil scope, embedded items, tank lining and mechanical interfaces are defined before execution.

YOUR PROJECT, YOUR DESIGN BASIS

Configure your requirement.

Enter what you know. Leave unavailable values blank for engineering review.

Process inputs

Industry type, effluent flow and operating hours, pH, COD, BOD, TSS, TDS, oil & grease, colour/metals/specific contaminants, equalization pattern, reuse/discharge target and treatability data.

Technologies you would like to discuss

Select candidates for review. This does not establish a treatment sequence.

Equipment & execution preferences

Materials are reviewed separately for each component against the fluid chemistry, temperature and service conditions. Preferences are subject to technical suitability and the agreed proposal.

No details are sent until you choose a sending channel.

A solution shaped by your requirements.

Flotation treatment for suitable suspended solids, fats and floatable contaminants. Treatment begins with understanding the effluent sources and their variability. Physical, chemical and biological stages are combined as appropriate, followed by polishing and sludge management.

What we review

  • Average daily flow and hourly inflow profile
  • Operating hours and peak-flow conditions
  • BOD, COD, TSS, pH, nutrients and relevant contaminants
  • Reuse or discharge objective
  • Available area, levels and site interfaces
  • Treatability, sludge handling and odour constraints

Capacity, materials, operating conditions and performance are specified after review of your project data. Product images are conceptual visualizations.

From design to operation

Our scope can cover process and mechanical engineering, manufacturing, supply, installation, commissioning and ongoing support. The final proposal clearly defines supplier scope, client interfaces, optional items and exclusions.
