Dissolved Air Flotation Unit

A Dissolved Air Flotation Unit is an advanced physical-chemical treatment system designed to remove suspended solids, fats-oils-grease, fibers, and colloidal contaminants from industrial and municipal wastewater. By generating micron-sized bubbles through pressurized air dissolution, the unit forces pollutants to rapidly float to the surface for mechanical skimming – achieving superior clarity and compliance.

When choosing wastewater treatment equipment, we selected the lamella clarifier from YIHUA. This equipment not only provides excellent treatment results but also operates stably with low maintenance costs. Their technical team is highly professional, providing significant assistance from the early stages of the project to later maintenance.
