1. Introduction
In modern industrial production, solid-liquid separation technology has become an indispensable part of multiple industries. Whether in metallurgy, chemical engineering, pharmaceuticals, food, or environmental protection, the performance of filtration equipment and filter materials directly affects production efficiency, product quality, and environmental protection. In the pesticide manufacturing industry, especially in the production process of glyphosate, the solid-liquid separation stage is critical. As one of the most widely used herbicides globally, glyphosate is produced on a large scale, and its separation and filtration tasks mainly rely on filter presses and their matching industrial filter cloths.
This article will focus on Xiamen Xiadias Vertical Filter Cloth for Filter Presses in the Pesticide Industry to discuss its functions and advantages in glyphosate production, combined with the market development trends in the pesticide industry, analyzing the application characteristics and future prospects of Xiamen Xiadias filter cloth products.
Processed material: pesticide glyphosate
2. Market Background of the Pesticide Industry
1. Overview of the Pesticide Industry
Pesticides are essential materials to ensure agricultural production and play a core role in global food security and stable crop yields. With global population growth and limited arable land resources, the overall demand for pesticides is on the rise. China, as a major global producer and consumer of pesticides, holds strong market advantages in subfields such as herbicides, insecticides, and fungicides.
2. Market Position of Glyphosate
Glyphosate is a broad-spectrum, systemic herbicide whose high efficiency and low residue characteristics make it one of the most widely used herbicides worldwide. Especially after the promotion of genetically modified crop planting, the market demand for glyphosate has continued to expand. According to relevant statistics, the global annual demand for glyphosate exceeds 700,000 tons, with China dominating in production capacity and exports.
However, the production process of glyphosate is complex, generating large amounts of by-products, wastewater, and waste residue, which impose higher requirements on separation and environmental protection. This is precisely where the filter cloth of the filter press plays a key role.
Filter press type: vertical filter press
3. Glyphosate Production Process and Filtration Stage
The main production routes for glyphosate are the glycine method and the double glyphosate method . Both processes involve steps such as reaction, extraction, crystallization, and separation, with solid-liquid separation being an indispensable key stage.
- Filtration of reaction slurry
During synthesis, a large amount of solid by-products are produced, which need to be separated by filter press. The filter cloth must be resistant to strong alkali, high temperature, and have high filtration precision.
- Mother liquor recovery and crystallization
The crystallization step of glyphosate requires repeated separation and washing. The filter cloth at this stage must ensure high water permeability and retention capacity while preventing loss of crystallized particles.
- Wastewater and waste residue treatment
The waste liquid from glyphosate production contains a large amount of organic substances and salts, and direct discharge causes serious pollution. After treatment by filter press, the chemical oxygen demand (COD) and suspended solids in the waste liquid can be effectively reduced, with the filter cloth playing a core role in this process.

4. Characteristics and Application Requirements of Filter Cloth for Filter Presses
1. Chemical corrosion resistance
The glyphosate production process uses many chemicals such as strong alkalis and strong oxidants. The filter cloth needs to have excellent acid and alkali resistance.
2. High strength and wear resistance
During operation, the filter press undergoes frequent mechanical pressing and repeated washing. The filter cloth must have strong tensile strength and tear resistance to ensure service life.
3. Balance between filtration precision and permeability
The filter cloth must effectively retain solid particles while allowing filtrate to pass quickly, improving filter press processing efficiency. This places higher demands on weaving technology and pore size design.
4. Anti-clogging performance
The particle size distribution of glyphosate reactants is uneven and easily clogs the filter cloth pores. High-performance filter cloth can improve slag discharge efficiency and reduce clogging.
5. Cleaning and regeneration performance
In continuous production, the filter cloth easily accumulates organic matter or inorganic salt crystals. High-quality filter cloth must have good adaptability to water washing and chemical cleaning for repeated use, reducing operational costs.

5. Combined Advantages of Vertical Filter Press and Specialized Filter Cloth
In recent years, vertical filter presses have been increasingly adopted by glyphosate production enterprises due to their high automation, small footprint, and high filtration efficiency. Compared with traditional plate and frame filter presses, vertical filter presses are more efficient in filtrate discharge and filter cake removal. These advantages need to be fully realized through high-performance filter cloth:
Automatic cake discharge The filter cloth must ensure uniform filter cake formation, easy detachment, and reduce manual intervention.
Adaptation to high concentration slurry During glyphosate production, the solid content is high, so the filter cloth must have strong load-bearing capacity.
Long-cycle stable operation High-strength filter cloth can maintain stable performance during long-term operation of the vertical filter press, avoiding frequent replacements.
6. Application Characteristics of Industrial Filter Cloth in the Pesticide Industry
Strong specificity The slurry properties vary greatly in different pesticide production processes, and the filter cloth needs to be customized according to process parameters such as pore size, material, and weave.
Environmental drive The pesticide industry faces significant environmental pressure, and filter cloth plays a decisive role in reducing wastewater and waste residue emissions.
Cost sensitivity The pesticide industry is highly competitive; filter cloth must ensure performance while also considering economy and durability.
Clear upgrade trend With the popularization of intelligent and automated equipment, filter cloth is developing towards high efficiency, long service life, and low energy consumption.
