Serum water from cup lump rubber is the main cause of disturbing odors in rubber block factories and has a very high treatment cost. Therefore, a prototype of a serum water treatment system using a multi-step biological process was studied to decompose the rottenness and treat the odor, using more than 60% less energy than before. The water that passes through the system contains microorganisms that can be used to wash rubber piles to reduce disturbing odors. In addition, it is suitable as a soil amendment because it contains the amount of nitrogen, phosphorus, and potassium that plants need on average, more than 0.8, 0.5, and 0.7 kilograms per cubic meter, respectively. The results of the study resulted in appropriate parameters for remote control of the system and further development of a data set to be able to track and control the automatic system in the future. In the next step, it will be expanded to use in the company’s two branch rubber block factories this year, including the concentrated latex factory and the raw material purchasing center.
