meas = measured alkalinity (mmol/l) Alk sa = alkalinity (mmol/l) due to S a buffer BNR = biological nutrient removal CH3COOH = acetic acid CO2 = carbon dioxide (mg/l) [CO2] = concentration of CO2 (mol/l) [CO32-] = concentration of carbonate (mol/l) CT = carbonate total species concentration (mol/l) = [H2CO3*] + [HCO3-] + [CO32-] GC = gas chromatograph HAc = acetic acid (mg/l) HCO3- = bicarbonate (mg/l) [HCO3-] = concentration of HCO3- (mol/l) H2CO3 = carbonic acid (mg/l) [H2CO3] = concentration of H2CO3 (mol/l) [H2CO3*] = [CO2 dissolved] + [H2CO3] (mol/l) HPLC = high performance liquid chromatograph H2PO4- = first dissociation step of phosphoric acid HPO42- = second dissociation step of phosphoric acid n = number of observations N = normality (mmol/l) NH3 = ammonia (mg/l) NH4+-N = ammonium nitrogen (mg/l) [NH4+-N] = concentration of NH4+-N (mmol/l) pK a = dissociation constant PO43--P = phosphate phosphorus (mg/l) r = correlation coefficient S = standard deviation S a = volatile fatty acids (mg/l), considered to be acetic acid SCFA = short-chain fatty acids TDS = total dissolved solids (mg/l) UASB = upflow anaerobic sludge blanket VA5-4,HCO3 = volume of acid (ml) required to titrate a sample from pH 5.0 to pH 4.0 due to HCO3-/CO2 buffer VA4,3,meas = measured volume of acid (ml) required to titrate a sample from initial pH to pH 4.3 VA5-4,meas = measured volume of acid (ml) required to titrate a sample from pH 5.0 to pH 4.0 VA5-4, sa = volume of acid (ml) required to titrate a sample from pH 5.0 to pH 4.0 due to S a buffer VFA = volatile fatty acids VS = volume of a titrated sample (ml) WWTP = waste-water treatment plant X = mean
