Abstract

Soya bean sauce waste water is a high organic wastewater and has dark color, therefore
it is difficult to degrade it biologically and also in getting clear color.
Base on as mentioned above, it is tried to process it with coagulation and flocculation
use Aluminum sulfate and PAC which is added to wastewater with several doses
variation of Alumunium sulfate: (100, 200, 300. 250) ppm and PAC with doses (50,
100, 150, 200) ppm.
Experiment result shows that the experiment which use Aluminum sulfate and PAC as
coagulant could give a good quality of processing and suitable with the threshold of
wastewater. The application of floculant Aquaklir 240 could help the performance of
coagulant that can be seen from the turbidity, suspended solid and flock size form.
