A new technology known as forced bed aeration (FBA) that can treat stronger chemicals in airport run-off is undergoing UK trials.

The new technology from ARM is capable of treating a wider range of effluents, including those with high-strength contaminants such as ammonia, petrochemicals, agricultural wastes and capped landfill leachate.

ARM director Tori Widdas said that an FBA reed bed could improve the treatment capabilities of a traditional reed bed by up to 15 times thus allowing reed beds to have a smaller footprint.

The technology has been used successfully in the US for the treatment of hydrocarbons and glycols.

FBA processes can also treat biogas digestate – a by-product of the anaerobic treatment of waste.
