本文对超滤技术应用中普遍存在着的诸多重要因素进行了讨论，有些内容在一般教材和文献中较少详细论述。本文从应用者角度分析了产率、吸附、消毒和保存、温控、活性问题、压力和透过速率以及技术联用应该注意的问题，并将其与膜质量参数、膜配置选择和操作模式相关联。对活性生物样品的处理，文中给予了较多的讨论，并希望结合超滤技术自身特点，在选择和配置一节中，对系统的各组成部分进行配置优化。应用中，安全性操作也贯彻于各个问题的讨论之内。在最后，涉及超滤法进行分子量分级的问题，提出了参数上的建议
This article discusses the many important factors that are common in the application of ultrafiltration. Some of the topics are discussed in more detail in general texts and literature. This paper analyzes the problems of yield, adsorption, disinfection and preservation, temperature control, activity, pressure and permeation rate and technology combination from the point of view of applicants, and discusses the problems with membrane quality parameters, membrane configuration selection and operation mode Associated. The treatment of active biological samples, given more discussion in the article, and hope combined with the characteristics of ultrafiltration technology, in the selection and configuration section, the system configuration optimization of the various components. Applications, security operations are also implemented in the discussion of various issues. In the end, the molecular weight classification of ultrafiltration is involved, and some suggestions on parameters are put forward
