Medium-active wastes of low-salt content can be treated by distillation in the same way as described above for highly active liquid waste. The small volume of concentrate produced from medium-active waste distillation can be combined with high-level waste arisings and the very low low-active condensate can be disposed of to sea in accordance with government authorizations. 

Medium-active waste also can be treated by floe precipitation processes similar in character to those widely used in water treatment. Precipitants are required which will remove the unwanted radioactive species from the waste solution and quickly settle, carrying the radioactivity into a small bulk of sludge. The supemate can be treated as a low-active waste and discharged locally to the environment. Typical precipitants for common cations are as follows.
