Regarding the mother liquor of the desulfurization system

The desulfurization system currently in use by the company’s Power Department generates sulfuric acid, which is used internally by the same company. However, the production wastewater also contains sulfuric acid an in relatively high amounts, along with many impurities. The mother liquor resulting from crystallization cannot be treated. I’m seeking advice from experts: is it possible to mix this sulfuric acid an mother liquor with that from the desulfurization system and use the mixture in a circular manner? What impact will it have on the desulfurization system?
It has a significant impact. 1. It may affect the specific gravity of the desulfurization mother liquor and pH control, resulting in poor desulfurization efficiency. 2. Equipment wear and corrosion issues in the presence of CL-. 3. The quality of the product affects subsequent handling.
The chloride ion content should not be a problem; it’s low, and no chloride ions enter during the manufacturing process； As long as the product quality isn’t significantly affected by impurities, it’s not a big issue; after all, it’s mainly for personal use at the moment. The main concern now is the potential impact on the desulfurization system, and the risk of causing it to fail. I want to know whether the impurities present in the sulfuric acid AN mother liquor can affect this system. The sulfuric acid AN content in the mother liquor is around 40%, along with other impurities such as proteins; its color is dark brown...
Should some of the sulfuric acid AN be removed from the mother liquor? How much of it needs to be removed? Could you provide a water quality report? If necessary, you can contact me at 15088793370; our company can help you resolve this issue
