Dissolved Air Flotation (DAF) System - Chemical Dosing & Advanced Advection for Efficient Green Water Treatment

Compact Chemical Dissolved Advection Air Flotation Unit – Small Footprint, Efficient Slurry Filtration

Business Overview
We specialize in the production and supply of a wide range of environmental treatment systems, including equipment for the petrochemical industry, municipal water services, urban and industrial wastewater treatment, domestic sewage purification, pure water production, reverse osmosis systems, water supply purification, and waste gas pollution management.

Product Introduction
The air flotation machine is designed to remove impurities from water through the use of micro-bubbles that cause suspended particles to rise to the surface. It is particularly effective for separating fine particles with a specific gravity close to that of water—which are otherwise difficult to settle or remove by conventional means.

Key Features

• Employs a dissolved air system that produces a large quantity of finely dispersed bubbles, allowing air to adhere to suspended particles and reduce their overall density.

• Utilizes buoyancy principles to float contaminants to the surface for efficient solid-liquid separation.

• Available in multiple configurations including super-effect shallow air flotation, vortex-concave air flotation, and advection air flotation.

• Suitable for applications in potable water treatment, industrial wastewater, and municipal sewage treatment.

• Compact structure, small footprint, automated operation, and user-friendly management.

• Low investment cost with high operational efficiency.

Applications
This equipment is widely used to remove suspended solids, oils, greases, and colloidal substances from various industrial and municipal wastewater streams. Typical industries include:

• 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 from lakes, reservoirs, and rivers

• Plant residues and fine colloidal matter

• Dye particles

• Short fibers from paper and chemical fiber production

• Oil droplets and organic solvents

• Heavy metal ions from electroplating and pickling wastewater

• Electrophoretic paint wastewater

Such particles have a specific gravity nearly equal to water, making them difficult to remove via traditional sedimentation—especially under low-temperature conditions where coagulation efficiency declines.

Air flotation technology represents a revolutionary alternative to gravity sedimentation. By introducing microbubbles that attach to flocs, the overall density of particles is significantly reduced, allowing them to float rapidly to the surface. This method greatly enhances solid-liquid separation efficiency and is particularly suited for treating light, suspended contaminants that are resistant to sedimentation.
