Product Overview
The Dissolved Air Flotation (DAF) system is equipment designed to remove impurities from water by introducing micro‑bubbles that attach to suspended particles, bringing them to the surface for separation. It is especially effective for treating fine particles with a specific gravity close to that of water, which are difficult to remove via sedimentation or natural flotation.

Applications
This equipment is designed to remove suspended solids, grease, and various colloidal substances from industrial and municipal wastewater. It is widely used across industries including:
Oil refining
Chemical processing
Brewing
Vegetable oil production and refining
Slaughterhouses
Electroplating
Printing and dyeing
Technical Process
In water and wastewater treatment, influent often contains lightweight suspended particles—such as algae, plant residues, colloidal impurities, dyes, short fibers, oil droplets, solvent residues, heavy metal ions, and electrophoretic paint particles—that have a specific gravity nearly equal to water.
Traditional sedimentation methods are often ineffective for such particles, particularly under low-temperature conditions where coagulation and hydraulic performance deteriorate. Instead of settling these challenging flocs, dissolved air flotation introduces micro-bubbles that adhere to the particles, significantly reducing their density. Using the natural buoyancy of bubbles, the flocs are rapidly lifted to the surface, enabling efficient solid-liquid separation. This innovative approach represents a major advancement over gravity sedimentation and expands the possibilities for separation technology.
Main Features
Utilizes a dissolved air system to produce finely dispersed micro-bubbles that adhere to suspended matter, reducing its density and allowing flotation.
Employs buoyancy principles for efficient solid-liquid separation.
Available in multiple configurations, including high-efficiency shallow DAF, vortex-concave DAF, and advection DAF.
Suitable for applications in potable water treatment, industrial wastewater, and municipal sewage.
Advantages include low investment cost, small footprint, high automation, and user-friendly operation and maintenance.
