Recommended pre-treatment technologies

Softening and activated carbon units Distillers (Vapour Compression and Multi Effect) are sensitive to feed water quality. In order to prevent scaling and corrosion in Vapour Compression stills, an appropriate pre-treatment plant must be designed and sized based on the feed water analysis.
