The relationship between the role of industrial filter cloth and environmental protection

1. Intercepting pollutants and controlling emissions
Industrial filter cloth intercepts solid particles, suspended matter and heavy metal ions in wastewater through physical screening and adsorption. For example, in the petrochemical and printing and dyeing industries, filter cloth can treat wastewater to be clear and transparent, with an adsorption rate of 99.99% of pollutants, reducing the risk of water pollution. In power plants, metallurgy and other industries, aramid or glass fiber filter cloth can capture 99% of dust and PM2.5 particles in flue gas, making the emission concentration lower than 10mg/m³, helping to achieve ultra-low emissions.

2. Resource recovery and recycling
Filter cloth separates concentrate and tailings in mining beneficiation, increasing the recovery rate by 20% and reducing ore waste; the chemical industry recovers intermediate products such as catalysts and resins through filter cloth to reduce raw material consumption. The combination of ultrafiltration membrane and filter cloth can intercept heavy metal ions in electroplating wastewater and purify water quality to meet reuse standards.

3. Reduce chemical dependence and ecotoxicity
Compared with chemical precipitation, filter cloth filtration does not require the addition of a large amount of flocculants, thus avoiding secondary water pollution. Food-grade polypropylene filter cloth replaces diatomaceous earth filtration in juice clarification, avoiding chemical additive residues and ensuring food safety.
