A Dissolved Air Flotation (DAF) Machine is an advanced water treatment process that clarifies wastewaters by the removal of suspended matter such as oil, grease, and fine solids. The process involves dissolving air in water under pressure and then releasing the air at atmospheric pressure in a flotation tank. The released air forms tiny micro-bubbles which adhere to the suspended matter, causing it to float to the surface where it is removed by a skimming device. As a leading China Dissolved Air Flotation Machine manufacturer, Qingdao Yimei specializes in engineering high-performance DAF units that ensure superior effluent quality for the most challenging industrial streams.
Depending on your hydraulic load and wastewater characteristics, we offer several specialized DAF configurations:
Horizontal DAF (High Capacity): The most common industrial DAF system, ideal for large flow rates and heavy solids loading.
Compact/Circular DAF: Designed for limited footprints, offering high-rate clarification in a smaller surface area.
Integrated DAF & Sedimentation: A patented hybrid system by Qingdao Yimei that combines flotation and settling functions to handle both floating grease and heavy sinking particles in one unit.
Cavitation Air Flotation (CAF): An economical alternative for simpler applications that do not require the high pressure of a standard dissolved air system.
Qingdao Yimei’s DAF units are recognized globally for their robust mechanical design and operational efficiency:
Patented Micro-Bubble Generator: Our system produces bubbles between 15–30 microns, significantly increasing the contact surface area and boosting separation efficiency by 40%.
Superior Material Durability: To withstand corrosive industrial environments, we offer full SUS304 or SUS316 stainless steel construction, providing a long lifespan and resistance to chemical erosion.
Energy-Efficient Dissolved Air System: Our optimized pump and saturation vessel design reduces energy consumption by 15-25% compared to conventional DAF models.
Smart PLC Automation: Integrated PLC control with a touch-screen interface allows for precise dosing control and automated sludge skimming, minimizing manual labor.
Visual Monitoring Port: Our unique patented observation window allows operators to inspect the flotation quality and sludge blanket thickness in real-time.
Our industrial dissolved air flotation machines are customized for high-impact performance in various sectors:
Petrochemical & Oil Refining: Essential for the removal of emulsified oil and petroleum hydrocarbons to protect downstream treatment units.
Slaughterhouses & Meat Processing: Highly effective at separating high-load animal fats, proteins, and blood solids from the process stream.
Paper & Pulp Mills: Used for fiber recovery and white water clarification, turning waste back into valuable raw materials.
Dairy & Beverage Industry: Removing milk fats and suspended organic solids that cause high COD (Chemical Oxygen Demand) levels.
