  • This study was performed to find effective measuring methods of retention and drainage by comparing traditional measuring methods of Britt jar, Canadian standard freeness tester methods and recently developed RDA-HSF with multi-channel turbidimeter method. At the result, Multi-channel turbidimeter method was useful to measure retention and efficiency of multiple chemical dosing system. A system CSF equipped with the balance recorder was also useful to obtain dynamic drainage information including initial drainage rate and final drainage amount. Therefore, we consider these new measuring systems would be helpful to advance retention and drainage technology.
