Air flotation
Air flotation covers a set of technologies designed to remove suspended matter, including fine solids, fats, oils and greases, from municipal wastewater, industrial effluent, water and oil-water mixtures. Read More
Liquids will often be pre-treated with chemicals, typically coagulants or flocculating polymers, to aid the process.
In dissolved air flotation (DAF) air is dissolved under pressure into the liquid to be treated and then released at atmospheric pressure into a tank.
This process releases tiny bubbles (20-80 microns in size) that attach to the suspended material, causing it to float to the surface. Skimmers remove the floating material for disposal, further treatment or material recovery.
In cavitation air flotation (CAF) the bubbles are produced by a rotating disk rather than under pressure.
With induced air flotation (IAF) the bubbles are formed by the mechanical agitation of injected air.

Dissolved air flotation units up to 100m3/hr
Siltbuster provides one of the UK's largest and most varied fleets of dissolved air flotation units. These mobile, readily deployable DAF units are increasingly popular for water treatment on remediation and construction projects. The range offers hydrocarbon and solids separation at flow rates up to 100m3/hrDAF in a BOX - plug-and-play dissolved air flotation range
DAF in a BOX takes Puriflo's DAF technology and packages it in a compact fashion that brings a new level of access and convenience to the provision of waste water purification. It can be installed on site in its container (no special housing required), plumbed in and ready for action in hoursAQUA-DAF high rate dissolved air flotation (DAF) unit
The performance of Colloide's Dissolved Air Flotation (DAF) unit is superior to that of similar or alternative technologies, both as a clarifier of primary or secondary effluent waters and as a thickener for biological sludge. The simplicity of the design of the AQUA-DAF system is at the core of its high operational reliability and versatilitySkid-mounted dissolved air flotation (DAF) unit rental
A skid-mounted dissolved air flotation (DAF) unit with a capacity of up to 30m3/hr is available for short- or long-term hire from MSE Systems. 5, 10 and 20m3/hr units are also available. In addition to the DAF unit itself, the system includes a self-contained containerised chemical dosing unit. It provides the facility for fully automaticDissolved air flotation plant for water and effluent
Aquatreat's dissolved air flotation (DAF) plant provides an effective way to clarify water, wastewater and effluent. Removal capabilities: suspended solids; fats; oils; greases; chemical oxygen demand (COD). Can be incorporated within treatment systems with minimal operating costs. Can be installed at the inlet of biological treatment for reducing pollutants- PRODUCT
Aquatreat Environmental ProductsiD DAF systems with integrated chemical dosing
Siltbuster's iD integrated units provided dissolved air flotation with combined chemical reaction tanks. The systems offer a reduced footprint and cost compared to the use of individual items, and also reduces installation time on site. The iD integrated units are also suitable for pilot trials to obtain data using real wastewater to confirmDissolved air flotation - DAF units
MSE Hiller DAF units have capacities from 4 to 100m3/hr. The compact, high-performing systems help meet discharge consents and reduce trade effluent bills. Units come complete with containerised coagulant dosing, pH correction and polymer dosing systems; feed and sludge transfer pumps all pre-piped, pre-wired, tested and ready for usePuriflo packaged dissolved air flotation (DAF) systems
Puriflo dissolved air flotation (DAF) systems come in a number of standard sizes, for example, for flotation areas of 4 x 1, 4 x 2 and 6 x 2m. Puriflo DAF systems are packaged units that are piped, wired and tested prior to delivery. The systems only require a feed pipe, discharge pipe, sludge pipe, a connection to chemical tanks, and a power
