Regarding the issue of phosphorus removal
Thread Content
A factory receives 700 T of water per day; the total phosphorus content in this water is around 20, while the COD level is 500. Just by adding chemicals, without any biochemical treatment, to what extent can these levels be reduced? What is the reason why the levels cannot be further reduced? I hope to get answers to the specific points. Thank you.

The effectiveness of phosphorus removal using primary enhanced coagulation depends on the distribution of the different forms of total phosphorus in the influent water; if all of it is in the form of orthophosphorus, then this method can reduce its concentration to below 0.5 mg/L. This method is not feasible in the presence of phosphorus bias or similar substances. Based on a comprehensive analysis, for wastewater containing phosphorus oxychloride, secondary treatment can be employed, and under normal circumstances the concentration can be reduced to below 0.5 mg/L.
