• Aquatec Maxcon uses a high efficiency saturator to dissolve air into a portion of the wastewater at a pressure of 300 to 600 kPa.  This portion is then recombined with the main wastewater under pressure.
• A valve subsequently reduces the pressure to near atmospheric, upon which an effervescence is induced in the wastewater by the formation of small bubbles of the order of 20 to 50 µm in diameter.
• These bubbles attach themselves to suspended solids and transport the solids to the surface, forming buoyant rafts or 'float'.  The depth of this float is controlled by adjustable height skimmers.
• In thickening applications, the float is allowed to form a thick raft of optimum depth (through adjustment) to enable gravity drainage of the liquid for maximum performance.

Coagulation and DAF can also reduce BOD, NFR and fats, oil and grease by up to 80%, 90% and 95%, respectively

• Mechanical simplicity through a bridgemounted drive unit for collection of float and bottom floc, thus avoiding greasy chain collectors and screw conveyors found in other designs.
• Simple on/off controls throughout to ensure ease of operation and to avoid unnecessary complex control loops.
• Fabrication can be in steel, concrete, or composite materials.
• Over 99% solids capture is regularly obtained even on thickening applications.
• Proven performance  over many years of service.
• Standard circular design provides minimum hydraulic gradient for optimum solids separation and enables a single drive unit for both float and floc scrapers.
• Design incorporates ability to build substantial float layers above the liquid level to enable gravity drainage and maximum float solids content.

Thickening of waste activated sludge to 5% without polymer addition is possible
