Wet cleaning of fumes by wastewater – Ecological project

PRECHEZA Přerov started The Washing of Fumes with SOx using contaminated waters from own chemical plants.

Cleaning of fumes with SO2 and SO3 contents by (expensive) caustic soda is widely known as reliable technique and simple alkaline technology.
Oxidizing washing by acid waters with Fe3+ sulphates is not almost used in the world.
PRECHEZA has these waters as the waste from TiO2 pigment plant.
Efficiency of this technology was confirmed – more than 85 % capturing.
