This research studies physicochemical characteristics which can influence process in order to treat sewage sludgeof stage 2 of resource recovery plant. In addition, it seeks also to reduce the variability which can be caused bytreatment processes and develop a plan for an unexpected situation. In 2014, we examined the factors which canhave an effect on plant stage 2 such as hydrogen ion concentration, moisture content, chloride ion concentration,viscosity, organic compound content, odor, etc. Moreover this research targeted sludge from twelve local areasthat is delivered to stage 2 of a resource recovery plant. Consequentially, the study has good results in hydrogenion concentration and moisture content. On the other hand, chloride ion concentration and viscosity cause increaseddrying time or corrode the facility, except for a part of the sludge. In addition, the study demonstrates that sludgeof a sewage treatment plant with a high organic content generates much odor when we researched odor and organiccontent. Moreover, organic compound content contributes to superiority in quality but could also be a weakness. According to the above seasonal data, the operation conditions of stage 2 facilities can be optimized if the sludgecarry-in of each local area is controlled or carried into other facilities.
