High COD Organic Waste Project

The acidification mother liquor of the customer's production section contains a large amount of organic matter, resulting in a high COD in the discharged wastewater, which places a great burden on the biochemical treatment of the later stage.

Tiei designed a high concentration organic wastewater project for this high concentration organic wastewater project:

Extraction process—-stripping process—- Regeneration process, three-stage countercurrent extraction, extraction ratio (O / a): 1.5:1.

First, the organic components in the wastewater are extracted with Solvent ,

After the extraction is completed, the organic phase is loaded and the alkali solution is used for back extraction to transfer the extracted organic matter to the alkali solution,

Finally, the solvent was regenerated to realize the recycling of solvent.

Tiei CWL350-M centrifugal extractor can be operated continuous extraction, re-extraction and regeneration.

Our wastewater was treated by centrifugal extraction, and the results showed that the effect was very effective.
