A Major Breakthrough in Solid-Liquid Separation Equipment: The New Nanometer- and Micrometer-Size Powder Filter Machine and the Technological Expertise of Citiuss

Against the backdrop of rapid advancements in high-end manufacturing, new materials development, and environmental protection, micron- and nanoscale powder materials are increasingly becoming a critical foundation for numerous cutting-edge fields. Whether in next-generation lithium-ion batteries, fine chemicals, high-performance ceramics, or front-end semiconductor processes, the purity and dispersibility of micron- and nanoscale raw materials directly determine the performance of downstream products. And highly efficient, precise, and stable solid-liquid separation equipment is precisely one of the core pieces of equipment that ensures the quality of these raw materials.

Xiamen Citius Environmental Filtration Technology Co., Ltd., based on its 30 Building on years of deep expertise in solid-liquid separation technology, we’re proudly launching a brand-new generation. Nano-micron powder filtration machine This device not only achieves breakthroughs in process performance but also integrates solid-liquid separation, washing, and drying into a single, compact system, marking a new stage of development for micro- and nano-scale powder processing equipment.

Challenges and Technical Hurdles in Micro- and Nanoparticles

The particle size of micro- and nanoscale powders is extremely small (typically less than 1000 nanometer-sized particles, which have a large specific surface area, strong surface activity, a tendency to agglomerate, and a slow settling rate—traditional filtration equipment often encounters challenges when handling such materials. Low filtration rate, poor retention efficiency, prone to clogging, high energy consumption. and other related issues. Meanwhile, to improve the cleanliness of the filtrate, traditional approaches often require the addition of auxiliary materials such as flocculants and filter aids, which not only increase operating costs but may also negatively affect product purity.

How to achieve it No chemical additives added. Under these conditions, precisely and efficiently separating micro- and nanoscale particles while simultaneously addressing the washing and drying of filter cakes has long been a persistent pain point in the filtration industry. It is against this backdrop that Citiuss has developed a new nano- and micro-powder filtration machine.

Technological Innovation: Redefining the Standards for Micro- and Nanopowder Filtration

The technical core of the new nanometer-scale powder filtration machine can be summarized as: “ Four Major Advantages ” and “ Three Major Integrations ”：

1. Ultra-high retention rate: Direct separation of micro- and nanoscale particles

The device features a high-precision filtration structure that enables direct physical interception of particles ranging from sub-micron to nano-scale. The interception efficiency is as high as 99.9% Even without adding any chemical additives, it can ensure that the filtrate is clear and has extremely low impurity content, meeting the stringent purity requirements of high-end industrial powders.

II. Pure physical filtration: No chemicals required, environmentally friendly

Unlike traditional treatment methods that require large amounts of chemical flocculation, this equipment employs... Full physical filtration mode There is no chemical intervention whatsoever in the treatment process. This not only reduces operational costs but also enhances the environmental friendliness of the product, serving as a prime example of the modern green manufacturing concept.

3. Integrated three-in-one structure: Filtration, washing, and drying are completed simultaneously.

The equipment integrates key functional modules such as filtration, backwashing, and drying, and through process synergy design, achieves continuous and efficient operation. High filter cake dewatering rate, fast drying efficiency, and excellent peel-off performance. It is particularly well-suited for production scenarios with high demands on filter cake recovery rate and ease of handling.

4. Low energy consumption, high automation

The equipment is fully controllable and programmable throughout its entire lifecycle, featuring a high degree of system automation and easy maintenance. Compared to conventional equipment, it significantly reduces overall energy consumption and boasts enhanced operational stability and cost-effectiveness, making it ideal for batch and continuous production scenarios.

Wide applicability: from non-metallic minerals to advanced powder materials.

This filter boasts an extremely wide range of applications, covering everything from traditional non-metallic mineral powders to new industrial synthetic materials, as well as the environmentally friendly recovery of fine particles from wastewater.
