Efficient Glyphosate Filtration Technology for Agrochemical Excellence

Project Background

As a major agricultural country, China has a significant demand for glyphosate, a non-selective, residue-free herbicide. In 2007, our analysis revealed that most manufacturers relied on the IDA or glycine production processes. While these methods were well-established, they offered limited potential for optimization, prompting the need for innovative solutions to improve efficiency.

Pain Points

The catalyst recovery and filtration process presented several inefficiencies:

Significant Catalyst Loss: Coarse filter cloths in traditional filter presses or centrifuges allowed fine catalyst particles to pass through, resulting in substantial waste of a valuable resource.

Labor-Intensive Operations: Manual transfer of filtered catalysts to reactors for reactivation was time-consuming and inefficient, slowing down production.

Poor Environmental Standards: The process created a disorganized and unclean production environment, failing to meet modern green production standards.

Solution

After over a year of on-site pilot testing, we developed an advanced filtration system to address these challenges:

High-Precision Filtration: Achieved single-pass filtration with a precision of 0.3μm, effectively retaining all catalyst particles to minimize waste.

Closed-Loop Process: Integrated dewatering, chemical reactivation, and slurry formation within a single, enclosed system, eliminating manual handling.

Seamless Workflow: Transformed catalysts into a slurry using compressed air bubbling, directly transferring it to the next process stage for enhanced efficiency.

Green Production: Enabled a cleaner, greener production environment by reducing waste and aligning with modern sustainability standards.

Subsequent Impact

Our solution has been widely adopted by industry leader Nantong Jiangshan Agrochemical & Chemicals Co., Ltd., with over 200 units of our equipment deployed. In 2010, our innovation was awarded a patent for “A Glyphosate Reaction Filtration Method and Dedicated Glyphosate Filtration Machine” by leading industry experts. This patented technology reflects our commitment to delivering sustainable, high-efficiency solutions for the global agrochemical industry.
