RORO AM (roll on roll off aerated media unit)

The RORO AM (roll on roll off aerated media unit) is a type of agile SAF that can be moved and deployed full of media and seeded. The units are hook lift and so can be moved easily and positioned wherever they are required, the speed at which they can be deployed means they are an excellent support system for emergencies and mechanical failures. The process has three internal sections that can be used as settlement, with media, fully aerated or empty- the configuration depends on the use. There are ten small blowers which can be used in isolated groups of three or four or all ten can operate at the same time. The units have an integral stairwell that folds up for transport. The self-contained unit can be used for tertiary, secondary or storm treatment and Severn Trent Water currently seeds them on a nursery site in order to deploy them ready to treat.
