Application
Sodium bicarbonate exhibits excellent multifunctionality in the field of water treatment, mainly through four key aspects: in terms of pH adjustment, it can effectively neutralize acidic wastewater generated by industries such as electroplating, chemical, and metallurgy, buffer pH fluctuations in biochemical treatment systems, and the optimal working range is 6.5-8.5; In terms of heavy metal treatment, it can form carbonate precipitation with heavy metal ions such as Pb ² ⁺, Cd ² ⁺, Cu ² ⁺, etc., which is particularly suitable for mine drainage treatment with a removal rate of over 95%; As an enhancer for desulfurization systems, it acts as a pH buffer in flue gas desulfurization (FGD) systems, which can replace some limestone to reduce operating costs and reduce equipment scaling risks; In terms of membrane treatment protection, it is used for pH adjustment of RO/NF system inlet water to prevent acidic corrosion of membrane components, which can extend the service life of the membrane by more than 30%. These applications fully demonstrate the high efficiency, economy, and environmental advantages of sodium bicarbonate in water treatment processes.
