Published on by in Technology

Do you use automatic control for chemical dosing of PAC for the total  phosphorus  ( TP ) removal?

Please share experience. Thanks.

    Phosphate normally can be removed by bio methods, you may use PAC or Aluminum sulfate for clarifying the wastewater, but after clarification contains foaming material, it means that the phosphate did not remove. But if you want to do the dosing process, in my experience, you should do it by testing the wastewater and some lab experiments to be able to calculate the dosing range.
