Abstract

Sewage is treated by combining it with a water-soluble peroxy compound and incubating it for sufficient time to reduce its bacterial content to an acceptable level; it can then be discharged, e.g. into the sea. A continuous process allows for mixing of sewage with the treatment compound, incubating of the mixture and discharging pre-treated mixture simultaneously. Compositions are provided, comprising the water-soluble peroxy compound, for use in sewage treatment.
