Removal efficiencies of chemical oxygen demand (COD), colour, ammoniacal nitrogen (NH3-N), total dissolved salts (TDS), and sludge volume index (SVI) were monitored throughout the experiments.
We left sludge-grey Britain and sailed on slate-coloured seas until we got to Panama, which came alive with colour and activity.

This paper reports a study of the colour, compressive strength and workability of mortar when cement is partly replaced by sewage sludge ash (SSA).
RED is the colour on Hungarians' minds today, as authorities battle to stop a torrent of toxic chemical sludge that has escaped from an alumina plant and already claimed four lives.
