Abstract :
The characteristics of highway service district sewage were investigated. High oil and grease contents were detected. A novel high efficiency oil isolation/coalesce apparatus(NOICA) was used to treat this type of sewage. Different coalesec materials and operational conditions were examined. Quartz sand was preferred to cinder and coal dust. Hydraulic loading was found to be the variable that affected the oil removal efficiency significantly. The optimum hydraulic loading should not higher than 21m3/m2.h, depending on swage characteristics. The removal efficiency of oil and grease exceeded 70% for most sewage tested. The experimental results also show that the temperature and pH also can affect the oil removal efficiency, and the optimum temperature and pH were 30degC,and 5.00-7.00 respectively.
