Acid production from zinc smelting flue gas; what causes the wastewater to be milky white?

Acid is produced from zinc smelting flue gas through acidified boiling roasting; when the sulfur dioxide concentration is above 7.5%, the purified liquid appears milky white, while it is reddish-brown under normal conditions. What factors influence this?

Sublimate sulfur; pay attention to adjusting the air volume in the roasting furnace

Reply to 1# chenchangyi: The possibility of sulfur sublimation is quite high; be careful with your pipelines, as well as the electrostatic mist lines and the filler devices.
