Wastewater generated from the production of seasoned salty plumes contains very high
levels of sugar alcohol, citric acid and sodium chloride with COD, NaCl and pH values of
about 120g g/l, 70g/l and 2-3, respectively.
For effective treatment of this concentrated wastewater，a lOO-time dilution is typically
applied thus requiring a large aeration tank. In this research, a yeast strain(UY7) isolated
from a plum-production wastewater treatment plant was shown to effectively cut the TOC
component of this high-strength waste. Favorable TOC reductions were achieved with
dilutions of only 3 to 10 times prior to biological treatment. The UY7 strain attached readily
to the biomass carrier（biofringe） composed of acrylic fiber. In continuous-treatment
experiments using a biofringe reactor, with an influent TOC of 14ｇ/l and a 5-time dilution
factor, TOC removals of about 40% were successfully obtained with HRTs of 1.0 to 2.5 days.
