The purpose of this research was to investigate and evaluate the impact of ECF process variables such as mixing, electrode types; initial pH, voltage supply and volume had on TSS, turbidity, pH, Chlorides (Cl-), and free chlorine (fCl2) and Hazen true colour removal. DoE Minitab software was used to design the order in which the experiments would were going to be run and analysed. Five factors set lower and higher values such as (i) mixing (0 to 500 r/min), (ii) Voltage (10 to 15 V), (iii) Initial pH (3.5 to 8.5), (iv) effluent volume (800 to 2000 mL) and (v) electrode types (aluminium and stainless steel) were investigated.

Generally, Hazen true colour, chlorides, and free chlorine analysis require sample preparation for pH adjustment and turbidity removal. The samples were centrifuged at 4500 rpm or filtered with 0.45 µm membrane sheets to remove or lower turbidity and neutralise to pH 7.6 to avoid interferences for some analyses.
