The dosage of chitosan and Trametes versicolor were 200, 400, 600, 800 and 1000 mg/L of the liquid waste product whereas the combination of chitosan and Trametes versicolor were 4:1, 3:2, 2:3 and 1:4. The data resulted from the analysis were shown as a graphics. The research results show that the optimum dosage of chitosan as coagulant was 800 mg/L which was able to decrease the colour intensity. For blue colour, the intensity decreased from 1.2 to 0.1%
