✦ Synopsis

The effect of different concentrations of copper or zinc on the anaerobic biodegradability of sludge has been investigated. An attempt has been made to correlate the metal forms with the performance of the digester. The presence of organically-bound copper is indicative of the deteriorated condition of the digester. However, an increased HNO, extractable fraction is associated with the failure of the zinc-spiked digesters.
