Treatment of catalysts in wastewater from wet flue gas desulfurization and dust removal following catalytic regeneration
Thread Content
During the maintenance of the catalytic unit, a large amount of catalyst sludge has accumulated in the sedimentation tank and oxidation regeneration tank of the catalytic flue gas wet desulfurization and dust removal system, making it very difficult to clean. How do these facilities handle desulfurization and dust removal wastewater? Are sludge dewatering machines or filter presses used?
The filter press we use works quite well
There are many in use, and their performance is really good
For the sludge treatment in the wastewater treatment system for wet desulfurization, vacuum belt dewatering machines or filter presses are still the preferred options in China at present. Traditional gravity settling still presents limitations in controlling the TSS of catalytic cracking catalysts, with the main issue being the poor effectiveness of flocculants. As for the catalyst accumulated in your clarifier and oxidation tank, high-pressure water cleaning can remove it completely.
What should I do with 100 cubic meters of sludge in my wastewater recycling tank?
