Treatment of Hazardous Waste

Our adsorbents can be regenerated, so it is very important to continuously optimize the regeneration technology from a cost-efficiency and environmental point of view.
In the case of regeneration of an arsenic-depleting adsorbent, an arsenic-rich regenerate is classified as hazardous waste.
The purpose of the development is to minimize this hazardous waste.
Regeneration requires commercially available chemicals, but no matter how much.
As a result of these improvements, hazardous arsenic was recovered from the regenerate by various processes and, in parallel, 90% of the chemical needed for regeneration was recovered.
