As the demand for particle purity and separation stability continues to rise in industries such as new materials, electronic pastes, nano-metal powders, and fine chemicals, traditional plate-and-frame filter presses and high-speed centrifuges have gradually revealed several limitations in nanometer- and micrometer-scale solid-liquid separation applications: rapid flux decline, frequent clogging, high energy consumption, and insufficient separation stability. Nanoparticles exhibit markedly different physical behaviors during filtration compared to micron-sized particles, making it increasingly difficult for conventional separation strategies—centered on high pressure or high rotational speed—to remain effective. This article starts from the fundamental mechanisms of solid-liquid separation and systematically analyzes the intrinsic differences between nanofiltration and traditional pressure filtration in terms of separation mechanisms, operational stability, and their impact on powder structure. It also compares the performance of nanomicro-powder filtration approaches with that of plate-and-frame filter presses and high-speed centrifuges in practical applications. Drawing on Xadias’ engineering experience in the field of nanomicro-powders, the article presents a nanomicro-powder filtration solution centered on structured interception and controllable filtration pathways. It emphasizes that filtration systems must be designed holistically around the specific characteristics of the powder itself, rather than simply relying on higher pressures or finer pore sizes. The article points out that, against the backdrop of the ongoing development of nanomaterials and high-value-added powders, filtration has transitioned from being merely an end-of-line treatment unit to a critical stage that significantly influences product performance and process stability. Therefore, the systematic upgrading of nanometer- and micrometer-scale filtration technologies will become a key development direction for future powder separation processes.
