Advanced Microbubble Dissolved Air Flotation System for Fine Particle Separation

The microbubble DAF system delivers exceptional treatment results across applications where the target contaminants are too fine or low-density for conventional separation methods. Surface water treatment plants drawing from reservoirs with seasonal algae blooms achieve complete removal of cyanobacteria cells and associated taste-and-odor compounds without excessive coagulant consumption. Printed circuit board manufacturing facilities treat copper-laden rinse water containing sub-micron metal hydroxide precipitates that pass through conventional clarifiers, recovering valuable metals while meeting stringent discharge limits below 0.5 mg/L. Dairy and cheese processing plants handling whey-containing wastewater remove fine proteinaceous solids and milk fat globules with diameters below 5 microns that resist gravity separation. Petrochemical facilities polishing dissolved air flotation effluent achieve additional removal of colloidal hydrocarbons prior to activated carbon adsorption, extending carbon bed service life by 40 to 60 percent. Aquaculture recirculation systems utilize the technology for fine solids removal from fish raceway effluent, maintaining water clarity while minimizing makeup water consumption and heating costs in indoor hatchery operations.
