Popis:	In this study, hydroxypropyl methylcellulose (HPMC) was used instead of concentrated sulfuric acid in the creaming process of skim natural rubber latex. In comparison to the process using concentrated sulfuric acid, the effluent acidity and sulfate ion were significantly lower but biochemical oxygen demand (BOD) and chemical oxygen demand (COD) were slightly higher. In overall, the pollution of the effluent from creaming process was reduced using recovered HPMC process In the effect of hydraulic retention time. In contrast, BOD and COD were increased. However, the high value of BOD and COD was valuable for wastewater treatment by anaerobic process.
