Abstract: The formate-utilizing sludge was first enriched in a chemostat reactor for over 90 days; at steady state, the sludge yield averaged 0.066 mg volatile suspended solids (VSS)/mg chemical oxygen demand (COD). The methanogenic ...

Abstract: The maximum capacity chemical oxygen demand (COD) loading in upflow anaerobic sludge blanket (UASB) reactors is evaluated using three 8.5 L reactors and high‐strength synthetic wastewaters composed of milk and sucrose at ...

Abstract: Wastewater containing high concentrations of cornstarch was treated in two 8.5-L upflow reactors: upflow anaerobic sludge blanket (UASB) and a modified anaerobic filter (AF). Both reactors were operated in parallel at 37°C ...

Abstract: Molybdate inhibited both sulfidogenesis and benzoate degradation in anaerobic treatment of wastewater, but the impact was more severe to the former reaction. In batch reactors, molybdate inhibition increased progressively ...

Abstract: Experiments were conducted at 37°C in an upflow anaerobic sludge blanket reactor treating wastewater containing phenol (200 mg/L),

Abstract: Effect of hydraulic retention time (HRT) on the acidogenesis of dairy wastewater was studied using an upflow reactor at pH 5.5, 37°C, and six HRTs ranging from 4 to 24 h. Results showed that the degree of acidification ...

Abstract: Acidification of lactose in wastewater was conducted in four series of experiments in an upflow reactor to investigate individual effects of hydraulic retention time (HRT) (2–24 h), lactose concentration in wastewater (2–30 ...

Abstract: The formation and characteristics of intracellular polymers in aerobic sludge of sequencing batch reactors were investigated at ambient temperature under balanced nutrient conditions. Three substrates of different chemical ...

Abstract: The upflow anaerobic-sludge blanket (UASB) process consistently removed 97–99% of chemical oxygen demand (COD) from wastewater containing concentrated mixed volatile fatty acids (VFA) at 37°C at loading rates of up to 24 g-COD/(L

Abstract: Formate in wastewater was effectively removed at 37°C by the upflow anaerobic sludge blanket (UASB) process. This was accomplished by keeping the recycle ratio at 3.0 and by lowering the pH of incoming wastewater to pH ...
