Jar Text Method:

  • StepsBWD-01 Water Decoloring Agent + PAC Coagulant + PH adjusted to 7.0-7.5 + PAM Flocculant
  • Prepare the solution for each chemical, and the laboratory apparatus and 1-14 pH test strips.
  • Dose 200-1000ppm BWD-01 (calculated as raw material), the exact dosage based on the different test, stir it for minutes till the small flocs generating.
  • Dose 500-1000ppm PAC (calculated as solid), the exact dosage based on the different test, stir it for minutes till the big flocs generating.
  • Test effluent pH, if not in 7-7.5, adjust with Acid or Alkali solution, sometimes, pH around 8-9 is better performance.
  • The effluent after pH adjusted, has flocs generated, dose 1ppm PAM (calculated as solid), stir slowly, till the flocs becoming big, and then stay for minutes for sedimentation.
