How Does Jiuwu Hi-Tech's Ceramic Membrane Technology Empower the Pigment Industry?

China is the world's largest producer and exporter of pigments, providing core supply for the vast printing and dyeing industry chain. As the pioneer of China's ceramic membrane technology, Jiuwu Hi-Tech, relying on its independent and controllable core technologies, has been deeply cultivating the field of industrial green separation. Addressing the core process pain points in pigment production, it has deeply adapted its mature ceramic membrane technology to dye production scenarios, customizing an integrated washing and purification solution for a pigment technology enterprise in Shandong — featuring a "pretreatment + ceramic membrane washing + ceramic membrane concentration" process.

With its precise molecular-level separation capability, this solution completely overcomes the inherent defects of traditional processes, effectively reducing energy consumption and production costs, and comprehensively improving production efficiency. It helps pigment manufacturers achieve multiple value enhancements — quality upgrading, energy saving and cost reduction, and environmental compliance — making it a benchmark application case for green and efficient production in the pigment industry.

Proven Project Implementation – Solid Results Demonstrate Technical Strength

In this project, the pigment synthesis liquid first undergoes a pretreatment step to remove large-particle impurities, then enters the ceramic membrane unit for desalination and impurity removal, followed by a concentration step to obtain a high-concentration dye liquid, which is then sent to the subsequent drying process. The results achieved are as follows:

● The purity of the pigment product has been significantly improved, with salt content greatly reduced and impurity pigments effectively eluted, resulting in a substantial enhancement of product quality stability.

● Washing water consumption in the production process has been reduced by more than 50%, significantly increasing the water recycling rate.

● Energy consumption in the subsequent drying step has been reduced by more than 30%, effectively compressing production energy costs.

● Total wastewater discharge across the entire process has been reduced by more than 60%, greatly alleviating the pressure on end-of-pipe wastewater treatment and reducing environmental compliance risks.

● Fully automated process control has reduced manual intervention, effectively lowering labor costs.

Jiuwu Hi-Tech Ceramic Membrane Empowers Solutions to Core Production Pain Points

Leveraging the sieving effect of membrane pores, ceramic membranes achieve molecular-level separation — small molecules such as water, salt ions, and pigments pass through the membrane surface as permeate, while pigment macromolecules are retained as concentrate. The key advantages include:

· High Temperature Resistance: Stable operation at high temperatures, withstanding up to 300°C+

● Chemical Corrosion Resistance: Resistant to strong acids, strong alkalis, and organic solvents, offering a wide range of applicability

● High Mechanical Strength: Inorganic materials resist deformation and damage, ensuring long service life

● High Separation Precision: Narrow pore size distribution (1 nm ~ 1.4 μm) for precise retention

● Easy to Clean and Regenerate: Supports backwashing and chemical cleaning, with high flux recovery

● No Phase Change, No Contamination: A purely physical separation process with no secondary pollution introduced

● Broad Applicability: Capable of handling complex feed streams with high viscosity, high concentration, and particulate content

For pigment manufacturers, adopting Jiuwu Hi-Tech's ceramic membrane solution is far more than a process iteration at a single production step — it represents the simultaneous realization of multiple values: quality improvement, cost reduction, consumption saving, and regulatory compliance. Ultimately, this technological dividend cascades along the industrial chain, empowering quality upgrades across the entire printing and dyeing value chain.

Jiuwu Hi-Tech's ceramic membrane technology, on the one hand, enables stable and controllable product purity, helping enterprises break through the quality ceiling of traditional processes, smoothly enter the high-end pigment market, and comprehensively enhance brand competitiveness and product added value. On the other hand, it significantly reduces wastewater discharge, helping enterprises confidently meet increasingly stringent environmental regulatory requirements and steadily achieve a green and sustainable production model.

Currently, the pigment industry is accelerating its evolution toward high-end, green, and intelligent development, and the penetration rate of ceramic membrane technology in the industry continues to rise accordingly. Moving forward, Jiuwu Hi-Tech will continue to deepen its expertise in the field of inorganic ceramic membrane technology, leveraging its deep technical accumulation and extensive engineering implementation experience to customize efficient and reliable separation solutions for more pigment and dyeing enterprises, jointly promoting high-quality green development across the entire printing and dyeing industry chain.
