without excess sludge.
However, as mentioned above, studies on PSB wastewater
treatment technology have barely touched on white spirit wastewater.
In this study, PSB were used to treat white spirit wastewater
to examine the feasibility of COD removal and biomass accumulation.
Crucial factors were tested to examine their influences on the
process, and dilution (reflux) was used to improve the treatment
performance. The aim of this study was to broaden the application
areas of PSB wastewater treatment technology.
