  • What is Pac based water treatment?
  • PAC is the polymer adopted by the Ghana Water Company Limited (GWCL) and the Barekese Water Treatment Plant management in Ghana. However, limited information is available on the optimal dosage and operating conditions for PAC-based water treatment.
  • What is the optimal dose of alum and Pac?
  • In this study, the optimal dose of Alum, with pH 8, was obtained 20 (mg/L) and the optimal dose of PAC (mg/L) was obtained 25. It was also observed that with increasing of the turbidity of raw water intake, especially on rainy days, the efficiency of coagulants decreased.
  • What is the Doc-normalized PAC dosage?
  • As the DOC concentration of the tested wastewater was 17.4 mg/L, the DOC-normalized, specific PAC dosage was 4.3 mgPAC/mgDOC.
  • What is the turbidity of a PAC flocculated water?
  • The average PAC dose, since its introduction in December 2016, was 33.2 mg/l, with minimum and maximum dosages of 14.1 and 43.8 mg/l. Since PAC's introduction, the turbidity of the flocculated water has remained fairly stable, within the range 3.5 to 6.1 NTU. When alum was in use, the range was 2.0 to 6.4 NTU ( Figure 4 ).
