The effects of engineering scale on the performance of a compost-based system for the remediation of a discharge from an abandoned metal mine in Cumbria, UK, has been investigated by the simultaneous operation of laboratory-scale columns, under both controlled laboratory and field conditions, and a pilot-scale system. Clear differences in the performance of the systems are seen, demonstrating the importance of environmental conditions and engineering scale. Early indications are that temperature, in particular, plays an important role in the attenuation of zinc within such systems. Implications for full-scale design of these treatment systems are discussed in this paper.
