Traditionally the powder polymer has been used in the sewage sludge treatment and water purifying plants. The powder polymer, however, has several problems such as bad working condition by dispersed powder and unstable operation of dehydrator by a lump of undissolved polymer. In this study, high accuracy automatic dissolving system for emulsion polymer is developed to reduce the cost of facility and is suitable for unit-process automation. This system is consist of the emulsion polymer storage tank, polymer dissolving solution supply tank, mixing chamber, micom and mobile system, etc. Performance tests for the system such as the rated flow of flowmeter, quantity of the tube pump, solubility of the mixing chamber, accuracy of micom and mobile system have been performed. The performance of the prototype system satisfies all the objects of this study.
