Product Description
Dissolved Air Flotation System

DAF operates on the principal of the transfer of floc to the surface of water through attachment of air bubbles to the floc. The floc accumulated on the surface, known as the 'float', is skimmed off as sludge. The clarified water is removed from the bottom and is sometimes called the subnatant or 'floated' water.

Since rain, snow, wind or freezing could cause problems with the float, flotation tanks must be fully enclosed in a building. The process is particularly suited to treatment of eutrophic, stored lowland or otherwise algae laden waters and soft, low alkalinity upland coloured waters. Like all clarification processes, flotation performance depends on the effectiveness of coagulation and flocculation. Polyelectrolyte dosing is often included to compensate for reduced performance at low water temperature or if the floc is fragile.

System Overview
Frequently Asked Questions
What is the primary function of the DAF system?
The Dissolved Air Flotation (DAF) system is designed to remove suspended solids, oils, and other contaminants from water by attaching micro air bubbles to the particles, causing them to float to the surface for removal.
What materials are used in the construction of the equipment?
The main body is typically constructed from high-quality Carbon Steel or Stainless Steel, with key internal parts made from S 304 or S 316 stainless steel for superior corrosion resistance.
Is this system suitable for low-temperature water treatment?
Yes, though performance can be affected by low temperatures. We often include polyelectrolyte dosing systems to compensate and ensure effective flocculation even in colder conditions.
Which industries commonly use this flotation machine?
It is widely used in paper mills, printing and dyeing, chemical processing, food and beverage production, slaughterhouses, and municipal sewage treatment plants.
Can the system be installed outdoors?
Because environmental factors like wind, rain, and freezing can interfere with the floating sludge layer, it is highly recommended to install the flotation tanks within a fully enclosed building.
What is the production capacity for these units?
We have a robust manufacturing capability, producing up to 8000 units per year to meet global industrial and municipal demands.
