The approximate range of water quality parameters for industrial wastewater
Thread Content
Could everyone please share information on the quality of the wastewater from their own facilities? What process is used? What will be the quality of the water output at the end? Let’s exchange ideas.
In our company’s processing process, certain highly polluted wastewater is pre-treated (decolorization, desalination, deammonification) before being combined with other water in a regulating tank, where it undergoes reaction and sedimentation followed by A/O treatment, after which the treated water is discharged. Water quality: The COD level in the regulation tank is 3000–4500; the removal rate through reaction and sedimentation is 25–30%. The COD level of the water exiting the A/O process is 350–440.
Our company only has a wastewater oil removal device; it cannot remove anything else
