How to treat APT production wastewater? There is a large amount of wastewater during the production process of APT (ammonium paratungstate). And the wastewater contains a large amount of magnesium sulfate, sodium sulfate and a small amount of heavy metal ions. So, it will cause serious pollution and waste of water resources if the production water is directly discharged without treatment. Then, how to treat APT production wastewater?

The researchers used the "neutralization + filtration + MVR evaporation crystallization + centrifugation + drying" process to treat APT production wastewater. And it was found that the pH value of the neutralization process was controlled to 11, and the treated wastewater could be used directly in the APT workshop, achieving the desired results. The production wastewater of APT treated by this process fully reflects the unity of economic benefits, environmental benefits, and social benefits, and has a good demonstration role in the domestic APT production industry.
