AI Overview
Sulphonation plant alkali wastewater, often containing high chemical oxygen demand (COD) and scrubber byproducts like
and
, is effectively treated using oxidation and evaporation. High-pressure oxidation (60–200 bar) or catalytic air oxidation converts sulphites and organics into harmless compounds, while evaporation crystallizes
for disposal or reuse, enabling zero liquid discharge.
