Abstract: The dynamic evaluation methods for anti-scalants used in reverse osmosis systems are reviewed. These methods include once-through method, full recycle method, partial recycle method and intermittent recycle method. Furthermore, the characteristics of the above four methods are analyzed and compared in respect of the change in solution concentration, water and chemicals consumption, chemicals residence time, scale types, scaling rate, and control model.

摘要： 综述了近年来反渗透专用阻垢剂的动态评价方法，包括给水一次通过法、全循环法、部分循环法、间歇循环法。从运行过程中溶液浓度的变化、化学药品的消耗量、模拟停留时间、结垢的种类等几方面对这4种评价方法进行了分析和比较，总结了各种方法的优缺点和适用范围，为人们选择和开发合适的阻垢剂评价方法提供了可靠的依据。
