| Summary, etc. | Yeast system coupled with microfiltration membrane, also called yeast membrane bioreactor, and is a promising technology used as pretreatment of biodegradable organic matter from saline seafood wastewater prior to secondary treatment for high organic strength wastewater and as secondary and advanced treatment for low organic strength wastewater. The experimental investigations were conducted by using lab-scale experiments, which were separated into five stages. In the first stage, biokinetic constant experiments were conducted in order to determine the growth rate of yeast sludge. The effects of different salt concentrations on growth rate were studied in this stage. It was concluded that growth rate of yeast mixture at high salt concentrations (32 and 45 g/L) was higher than that of activated sludge. In the second stage, the batch experiments were conducted in order to determine the optimum operating condition for yeast membrane bioreactor. The effects of different sludge retention time and nutrient loading were studied in this stage. The results showed that yeast reactor run at SRT of 10 d, influent COD of 5000 mg/L could obtained around 80% COD removal. Main mechanism of nitrogen removal in yeast reactor is nitrogen uptake process into biomass. However, precipitation of protein at low pH which is adjusted to 3.5 to 3.8 for yeast growth and inhibition of bacteria contamination may attribute to nitrogen removal. In the third stage, the continuous YMBR experiment was conducted in order to determine the optimum hydraulic retention time. The results show that the YMBR run at HRT of 24 h with influent COD concentration of 5000 mg/L could remove 85% of COD. Moreover, membrane bioreactor run at HRT of 8 h with influent COD concentration of 1000 mg/L could achieve effluent COD quality met the effluent standard set in Thailand after neutralization. In the fourth stage, membrane-clogging experiment was conducted. From the experimental results, it was concluded that yeast system could prolong the operation period of membrane without chemical cleaning than that of bacteria system. In the fifth stage, characteristics of sludge with different salt concentration were determined on the dewaterability of the sludge. It can be concluded wide yeasts acclimatized in this study has poor settling ability, but inversely it has good dewatering ability. Therefore using membrane technique for yeast treatment could overcome this disadvantage and as well as obtain high effectiveness for dewatering, increasing membrane performance and running with low pump pressure |
