Efforts were made to identify the optimum operational condition of Semi-continuously Fed and Mixed Reactor (SCFMR) to treat the dairy cow manure and saw dust mixture. Step-wise increase in organic loading rates (OLRs) and decrease in hydraulic retention times (HRTs) were utilized until the biogas volume became significantly decreased in SCFMR at mesophilic temperature (35oC). The optimum operating condition of the SCFMR fed with TS 15% dairy cow manure and saw dust mixture was found to be at HRTs of 30 ~ 35 days and its corresponding OLRs of 3.5 ~ 4.3 kgVS/ m3-day. The optimum ranges of biogas and methane production rates were 1.36 ~ 1.47 volume of biogas per volume of reactor per day (v/v-d) and 1.0 ~ 1.14 v/v-d, respectively. This result was due to the high alkalinity concentration of SCFMR fed with the original substrate, dairy cow manure and saw dust mixture whose alkalinity was more than 10,000 mg/L as CaCO3. The parameters for the reactor stability, the ratios of volatile acids and alkalinity concentrations (V/A) and the ratio of propionic acid and acetic acid concentrations (P/A) appeared to be 0.07 ~ 0.09 and 0.38 ~ 0.43, respectively, that were greatly stable in operation. The Total Volatile Solids (TVS) removal efficiency based on the biogas production was 39 ~ 45% at the optimum HRTs. Free ammonia toxicity was not experienced at above 160mg/L due to the acclimation of high concentration of ammonia by the high reactor TS content above 9.0%.
