With the development of modern science and engineering technology, solid-liquid separation technology and equipment have penetrated into high-tech and emerging industries such as energy, environment, biology, and new materials, becoming these new science and technology and modernization, petrochemical, pharmaceutical, and light. Indispensable technologies in industrial technology fields such as industry, food, agricultural and sideline products processing, water resources development and recycling, and human daily life. In many production processes, diaphragm filter press is one of the key equipment, and its level of technology directly affects the advanced nature of modern industrial production. With the increasing environmental problems, energy shortages, water resources and resource depletion in the world, how to save and use resources effectively becomes the fundamental problem of maintaining human sustainable development. This must rely on efficient and high-quality filtration and separation technology. Therefore, in recent decades, the solid-liquid separation technology has developed rapidly, and the requirements for solid-liquid separation are also higher. It requires low energy consumption, economy, and high efficiency.
The research and application of filtration technology with large throughput and high separation efficiency has become more important and urgent.
