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 ...

Abstract: The upflow anaerobic sludge blanket (UASB) process removed 97–99% of soluble chemical oxygen demand (COD) from wastewater containing concentrated benzoate at 37°C, pH 7.5, a hydraulic retention time of 9.8 h, and loading ...
