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 highly effective DAF process efficiently ‘floats’ stubborn hydrocarbons with a near neutral buoyancy off to the water’s surface – where a mechanical scraper drive recovers the product ready for disposal.

The extensive Siltbuster DAF range offers hydrocarbon and solids separation at flow rates up to 100m3/hr and is suitable for both construction and remediation sites.

Operation

Using established solids/liquid separation technology, the DAF units generate ‘white-water’ by dissolving air under pressure and then releasing the pressure to form micro fine air bubbles. The target particulates attach to the air bubbles causing them to rise to the surface, where they thicken by natural de-watering and are scraped off. The Siltbuster range of chemical dosing systems can be combined with these units to offer enhanced removal when you need to meet tight consents or for those difficult to treat applications.
