In laboratory pilot-scale tests of chemical R&D, wastewater resource treatment, and raw material purification, the 10-stage experimental PP mixer settler has become a core, necessary of equipment for process verification across various industries. With the corrosion-resistant properties of polypropylene and 10-stage counter-current series structure, the mixer settler helps companies complete extraction process parameter debugging, formula optimization, and feasibility verification at low cost, accurately mitigating risks associated with industrial-scale production and laying a solid technical foundation for large-scale manufacturing.



Widely application, core equipment tested in multiple scenarios

The10-stage lab PP mixer settler is suitable for a wide range of applications, including hydrometallurgy, pharmaceuticals and fine chemicals, environmental wastewater treatment, food and biological research and development, and scientific research and teaching. It is a core equipment for small-scale purification, separation, and recovery of various materials.

★ Hydrometallurgical field
The mixer settler is widely used for the purification and refining of leaching solutions from minerals such as nickel, cobalt, vanadium, rare earths, and lithium salts. Companies can use this mixer settler to complete small-scale trials of the entire process, including segmented extraction, precise washing, and efficient back-extraction, quickly screening suitable extraction reagents, and optimizing core process parameters such as acid-base ratios and feed flow rates, providing precise data support for the resource-based purification of minerals.

★ Pharmaceutical and fine chemical fields, 
The mixer settler is a key of equipment for new drug development and the purification of refined products. For various pharmaceutical intermediates, alkaloids, fragrance oils, lactic acid fermentation broths, and other materials, it can precisely explore separation, purification, and refining process conditions, solving the pain point of not being able to directly implement large-scale production lines during the new drug development and new product trial stages, and assisting in product formulation iteration and process finalization.

★ Environmental wastewater treatment, 
The mixer settler has become a mainstay equipment for wastewater resource recovery. It can specifically complete small-scale tests on various corrosive wastewaters such as electroplating wastewater containing nickel and copper, pesticide and chemical wastewater containing phenol, and pickling waste acid. It efficiently verifies solutions for pollutant removal, organic solvent recovery, and waste acid resource utilization, helping enterprises achieve dual benefits of wastewater treatment meeting standards and resource recovery.

In addition, the mixer settler is also adaptable to scenarios such as food additive extraction, bio-fermentation broth purification, and scientific research and teaching in university and enterprise laboratories. It can stably complete various extraction formula experiments and process simulations, demonstrating extremely high versatility.

The 10-stage countercurrent design of mixer settle offers significant advantages over traditional equipment.

Compared to traditional manual extraction devices such as beakers and separatory funnels, and other simple single-stage extraction equipment, the 10-stage experimental PP mixer settler achieves a comprehensive upgrade in extraction efficiency, product purity, and experimental stability thanks to its mature 10-stage countercurrent contact technology.

The mixer settler employs a multi-stage segmented countercurrent contact process, ensuring thorough countercurrent contact between the feed liquid and the extractant, significantly improving the capture efficiency of target substances. Actual measurements show that material extraction recovery rates can be increased by 15%-30%, and the extraction stability rate for most materials can reach 85%-99%. Impurity retention capacity is significantly improved, optimizing product purity from the source and avoiding problems such as incomplete extraction and impurity residue.

The cell body is made of high-quality PP, possessing extremely strong corrosion resistance. It can withstand long-term erosion by strong acids, strong alkalis, and various organic solvents, eliminating tank damage and leakage caused by acidic or alkaline solutions and corrosive solvents. The mixer settler operates stably and is durable. It can also be equipped with a customized gas collection hood to effectively collect volatile organic solvents, reduce experimental waste gas leakage, optimize the laboratory operating environment, and balance safety and environmental protection.

The equipment operates based on the principle of natural stratification and phase separation by gravity, eliminating the need for complex pressurization equipment. By adjusting the stirring speed and feed-discharge ratio, it can adapt to materials with different viscosities and properties, demonstrating extremely high adaptability. Its core advantage lies in the high repeatability and accuracy of pilot-scale test data. The obtained process parameters can be directly scaled up to large-scale industrial equipment, perfectly resolving the disconnect between pilot-scale and mass production processes, avoiding the risk of production failure, and significantly reducing the experimental waste of reagents and raw materials, effectively lowering the R&D and pilot-scale production costs for enterprises.
