Activated bleaching clay is a highly efficient and eco-friendly adsorbent material produced through acid activation treatment of natural bentonite. It features a high specific surface area and well-developed microporous structure, delivering exceptional adsorption performance for removing pigments, impurities, and harmful substances from oils, petroleum, and other liquids.
Widely applied in edible oil decolorization, lubricant regeneration, and industrial wastewater purification, activated clay maintains stable performance during decolorization processes—significantly improving product purity while preserving the original properties of treated media.
Our product undergoes strict quality control to meet both food-grade and industrial standards, ensuring non-toxicity and easy recyclability. We offer customized solutions with various particle sizes and activity levels to help clients achieve cost reduction and efficiency improvement.Choosing activated clay means opting for a safe and reliable adsorption solution.

What are the advantages of activated bleaching clay? | |
Activated bleaching clay, as a high-performance adsorbent material, offers multiple significant advantages: 1.Outstanding Adsorption Capacity Featuring a unique microporous structure and surface acidic sites, it effectively captures oils, pigments, and heavy metal ions with a decolorization rate exceeding 90%. The adsorption process preserves the active components of the medium, making it ideal for precision purification in edible oils, biodiesel, and similar applications. 2.Remarkable Environmental Benefits Sourced from natural bentonite, its production generates no toxic byproducts. Post-use, it can be regenerated through high-temperature treatment or safely landfilled, aligning with circular economy principles. These properties give it tremendous potential in industrial wastewater treatment and soil remediation. 3.Exceptional Application Flexibility By adjusting activation parameters, products can be customized in adsorption capacity, particle size, and pH adaptability to meet diverse needs—from lubricant regeneration to petrochemical desulfurization—significantly reducing material waste and processing costs. Moreover, its high chemical stability maintains adsorption performance even under high-temperature and acidic conditions. With food-grade certification, it's safe for sensitive industries like pharmaceuticals and cosmetics. Choosing activated clay means opting for an efficient, safe, and sustainable adsorption solution that combines technical excellence with environmental responsibility. Its versatility and performance make it an ideal choice for modern industrial and environmental applications. | |
