目前，当设备过滤单元的设计者希望准确地确定其目的所需的安装尺寸时，在文献中几乎找不到具有直接价值的信息。本研究的目的是研究使用商业尺寸过滤器的压滤机容量的一些因素，并展示表达流量、压力和滤饼厚度之间关系的简单基本方程的适用性。它还旨在展示增加压力的正确方法以及最有效的过滤周期长度。这些测试是由麻省理工学院化学工程实践研究生院的学生进行的，作为常规课程的一部分，顺便说一句，它们形成了学生所接受的培训和经验的典型说明。其中两名学生 A. J. Hartsook 先生和 J. Keats 先生负责测试，主要负责测试的设计和性能。这项工作是在马萨诸塞州查尔斯敦的里维尔糖精炼厂进行的，该厂是化学工程实践学院的合作公司之一。 理论讨论 从各个实验者的工作中，可以肯定地说，液体通过过滤介质的流量与压力的某些次方成正比，与滤饼的厚度成反比。它还与暴露的过滤表面面积成正比。我们可以用等式来表达这些关系
There is at present to be found in the literature very little information that is of immediate value to the designer of the plant filtration unit, when he wishes to determine accu-rately the size of installation necessary for his purpose. The object of the present investigation was to study some of the factors determining the capacity of a filter press, using commercial-size filters, and to show the applicability of a simple fundamental equation expressing the relationship between rate of flow, pressure, and thickness of cake. It was also purposedto demonstrate the proper way to increase the pressure and also the mostefficient filter cycle length. The tests were performed by students in the Graduate School of Chemical Engineering Practice of the Massachusetts Institute of Technology, as a part of the regular course, and, incidentally, they form a characteristic illustration of the training and experience the students receive. Two of the students, Messrs. A. J. Hartsook and J. Keats, were in charge ofthe tests and were mainly responsible for their design and performance. The work was carried out in the plant of the Revere Sugar Refinery, Charlestown, Mass., one of the cooperating companies of the School of Chemical Engineering Practice.Discussion of Theory From the work of various experimenters, it is safe to say that therate of flow of liquid through a filtering medium is proportional to some power of the pressure, and inversely proportional to the thicknessof cake. It is also proportional to the area of filtering surface exposed. We may express these relationships by the equation
