The addition of solids or liquids into solutions is a very important issue in many industrial processes, such as oil sands, drinking water treatment, cosmetics and personal care products, and paints and coating. The efficiency of these processes may be improved if an efficient dispersion and dissolution of these additives is achieved. In order to improve process efficiency, the mechanisms involved in the addition of these solids need to be understood. While the mechanisms are studied at the bench scale, these tests do not always represent the real characteristics at the industrial scale. For example, a bench scale test should use 1L or less of sample, while an industrial scale vessel in the oil sands industry may hold 10 000 L or more.

将固体或液体添加到溶液中在许多工业过程中是非常重要的问题，例如油砂、饮用水处理、化妆品和个人护理产品以及油漆和涂料。如果实现这些添加剂的有效分散和溶解，则可以提高这些方法的效率。为了提高工艺效率，需要了解添加这些固体所涉及的机理。虽然机理是在实验室规模上研究的，但这些试验并不总是代表工业规模上的真实的特征。例如，实验室规模测试应使用1 L或更少的样品，而油砂行业中的工业规模容器可容纳10 000 L或更多。
