Meanings of treat effluent in English

The Rabie Group, a large construction company, uses treated effluent water to make concrete and wash equipment on its Cape Town sites.

Even so, the presence of supported nanotubes during ozonation seems to be required to reduce the toxicity of the resultant treated effluent.

Some local environmentalists said the treatment didn't go far enough, and that it was dangerous to send partially treated effluent back into the sea.
