How is the saline wastewater generated from flue gas desulfurization treated? Do you handle it? We are now sending it to the wastewater treatment plant

The quantity won’t be large; sending it to a wastewater treatment plant is an economical method.
Alkali solution is added and aeration is carried out to produce purified water.
It depends on the composition of your wastewater; the method used for desulfurization determines whether magnesium can be used to produce magnesium sulfate；
If **discharging saline wastewater is restricted, it’s really a problem.
Currently, alkaline and ammonia methods are primarily used for catalytic flue gas desulfurization
Direct discharge to wastewater treatment plants; currently, external discharge requirements for wastewater containing salts are not too strict
Are there many devices used in your method?
If stricter controls are imposed on wastewater discharge standards in the future, this salt content parameter might be included as well
