| Abstract: | The core of freeze concentration process is creating ice crystals with large size and high purity. Urine is adopted as a sample for experiment. Effects of coolant temperature, ice crystal form, initial temperature, solution concentration, seed ice, re-crystallization process and crystallization time on ice crystal purity are analyzed by experiment. Based on these, measures that should be taken to improve ice crystal purity are put forward. |
