Factorial optimization of Coagulation-Flocculation process for Abattoir Wastewater using Carica Papaya seed extract as bio-coagulant

The objective of this research was to optimize the coagulation-flocculation process for abattoir wastewater by utilizing a bio-coagulant derived from Carica Papaya seed (CPS). (CPC) extracted using 2M NaCl solution, and carried out bench scale jar test. Applying design expert (13.0.5.0), 23 full factorials with 5 center points, effects three factors: coagulant dosage (X1), pH (X2), temperature (X3) on turbidity reduction efficiency were examined. ANOVA, it discovered that linear model best characterizes process, significant p-value 0.0015, showing is significant. Additionally, component in model, 0.02 indicating statistically A 90.02 % attained at optimum conditions 0.75g/L CPC, 6, 308 K.
