Concept:DAF generates microbubbles to attach oil, suspended solids and colloids, forming low-density flocs that float up for fast solid-liquid separation.
Functions:Remove oil, fiber, algae and light suspended solids;Cut COD by 75%–85% & SS over 95% to ease subsequent biochemical treatment;Replace secondary sedimentation tank and thicken sludge
Working Flow:Treated water pressurized & saturated with air → released via releaser to form tiny bubbles → bubbles bond flocs → scum skimmed, clean water discharged
Advantages:High separation efficiency; short retention time & small footprint; adjustable parameters & optional anti-corrosion materials; PLC auto dosing & slag scraping.
Types & Applications
Standard DAF: Printing, electroplating, chemical, food wastewater, algae removal
Shallow DAF: Large flow papermaking water recovery, industrial park pretreatment
CAF Cavitation Air Flotation: High-concentration organic wastewater pretreatment Industries…
