PRODUCT INFORMATION
Overview & application
1. Product Introduction | Dissolved Air Flotation (DAF) System
The ODMS Dissolved Air Flotation (DAF) System is designed to remove suspended solids, fats, oils and grease from wastewater through a flotation process. By dissolving air into pressurized water and releasing it as fine bubbles, the system attaches bubbles to suitable particles and droplets, lifting them to the water surface for skimming and separation.
Widely used in municipal and industrial wastewater treatment, DAF is particularly suitable for applications involving lightweight suspended solids, oily wastewater and coagulated or flocculated particles. Typical applications include food processing, slaughterhouses, pulp and paper production, textile processing and petrochemical wastewater treatment, subject to wastewater characteristics and process design.
The system can be configured with a flotation tank, pressurized recycle-water circuit, air dissolution and release components, skimming mechanism and chemical dosing equipment where required. ODMS equipment selection is based on wastewater flow, solids loading, oil and grease characteristics, separation objectives and available installation space.
2. Reduce Contaminant Load Before Downstream Treatment
Continuous Solid-Liquid Separation for Difficult-to-Settle Solids, FOG and Flocculated Contaminants
01|Efficient Solid-Liquid Separation
Float Difficult-to-Settle Contaminants
DAF uses fine air bubbles to float fine, low-density and difficult-to-settle contaminants for efficient surface removal.
02|FOG & Low-Density Contaminant Removal
Effective Removal of FOG and Suspended Solids
Ideal for food, slaughterhouse, meat processing and dairy wastewater, DAF separates FOG, suspended solids and flocculated contaminants through flotation.
03|Reduced Downstream Treatment Load
Remove Contaminants Before Biological Treatment
DAF removes separable solids and FOG upstream, reducing the contaminant load on downstream biological processes and helping stabilize influent conditions.
04|Continuous Operation
Built for Continuous Wastewater Treatment
Continuous influent, flotation, sludge skimming and clarified-water discharge support stable operation and simplified daily management.
