AI Overview
Sulphonation plant scrubber wastewater crystallization is a Zero Liquid Discharge (ZLD) process that treats acidic scrubber wastewater by neutralizing it, concentrating it via evaporation (often using waste heat), and crystallizing sodium sulfate (
) salts. The process oxidizes sodium sulfite (
) to
and evaporates water to produce dry, manageable crystal waste, preventing environmental discharge.
