flue gas desulfurization wastewater
Flue gas desulfurization (FGD) wastewater is the by-product of the process used to remove sulfur dioxide from the exhaust gases of coal-fired power plants. The main use of this system is to treat and purify the waste water caused by desulfurization, in order that harmful pollutants have been turned into harmless sulphates. Just among its technological features are advanced filtration systems, chemical treatment processes, and evaporation or crystallization recovery to extract valuable constituents These wastewater treatments are crucial for power plants--especially those burning coal; and they help match environmental laws. Its uses span the spectrum from pretreatment of raw water intake to the making of pure water that either can be used again or safely discharged, thus illustrating its vital role in sustainable industrial production.
