BATCH TEST METHOD FOR MEASURING METHANOL UTILIZER MAXIMUM SPECIFIC GROWTH RATE
Abstract:A batch test method is presented for estimating the maximum specific growth rate of methanol-utilizing heterotrophs (μMETH) in activated sludge systems where methanol is added for denitrification. The method is analagous to the High F/M Method for estimating the maximum specific growth rate of nitrifiers (μAUT) (WERF, 2003). The test also can be used to estimate the COD/N ratio for methanol; that is, the amount of methanol required for the removal of nitrate (mgMeOH/mgNO3-N). This ratio can in turn be used to calculate the yield coefficient for the methanol-utilizing heterotrophs (YM).
