Microsorb® Attapulgite Adsorbent & Filtration Media
Overview Microsorb® 30/60 RVM by Clariant is a thermally activated, granular attapulgite adsorbent and filtration aid designed for liquid clarification, contaminant removal, agricu ltural carrier applications, and other industrial processes requiring precisely sized sorptive media. The RVM grade combines a high level of sorptivity with intermediate particle strength. It can be used in fixed beds, cartridges, and suitable contact-filtration systems to decolorize, deodorize, and remove surfactants, water, and other polar impurities from organic liquids. Primary applications Fuel and oil filtration: Filtration of contaminants from jet fuel, kerosene, non-edible oils, and other compatible liquid streams Liquid clarification: Removal of suspended contaminants and polar impurities from process liquids Decolorization and deodorization: Treatment of organic liquids containing unwanted color bodies, odors, or oxidation-related impurities Surfactant and moisture removal: Adsorption of surfactants, low concentrations of water, and other polar contaminants Static-bed and cartridge filtration: Granular media for packed-bed, cartridge, and related filtration configurations Agricultural carrier applications: Carrier and diluent media for compatible pesticide and toxicant formulations Industrial sorbent applications: Sorptive granular media for selected cleanup, surface treatment, and industrial handling uses Why choose Microsorb®? Thermally activated attapulgite with a high level of sorptivity Granular 30/60 mesh sizing for controlled flow and filtration performance Intermediate particle strength suitable for a range of sorbent and filtration systems Effective for decolorization, deodorization, and removal of polar impurities Suitable for static-bed, cartridge, and appropriate contact-filtration applications Available in multiple packaging formats for laboratory, trial, and production quantities Manufacturer testing indicates potential reduction of heavy-metal concentrations and certain microbial contaminants in appropriate liquid-treatment systems Performance depends on the liquid composition, contaminant concentration, equipment, contact time, and operating conditions. Customers should validate suitability for their individual process.

Questions & answers Q: What is Microsorb® 30/60 RVM?A: Microsorb® 30/60 RVM is a thermally activated granular attapulgite product manufactured by Clariant for sorbent, filtration-aid, and agricultural carrier applications. Q: What does RVM mean?A: RVM means Regular Volatile Matter. Clariant describes the RVM grade as having a high level of sorptivity and an intermediate level of particle strength. Q: What contaminants can Microsorb® remove?A: Microsorb® can be used to decolorize, deodorize, and remove surfactants, water, and other polar impurities from compatible organic liquids. Performance depends on the process and should be validated through application testing. Q: Can Microsorb® be used for fuel and oil filtration?A: Yes. Clariant identifies jet fuel, kerosene, various non-edible oils, and other compatible liquid streams among the filtration applications for Microsorb® products. Q: Can Microsorb® reduce heavy-metal concentrations?A: Clariant reports that testing has shown its attapulgite products can reduce concentrations of heavy metals in certain liquid streams. Removal performance depends on the contaminant, liquid chemistry, operating conditions, and treatment design. Q: Is Microsorb® intended for high-moisture feed streams?A: The manufacturer recommends Microsorb® RVM where the incoming concentration of water as a contaminant is relatively low. Applications with substantial moisture may require a different adsorbent or treatment approach. Q: How is the 30/60 mesh grade used?A: Granular Microsorb® grades may be used in static beds, cartridge systems, and other compatible filtration configurations. Equipment suitability and pressure-drop requirements should be evaluated before use. Q: How does Microsorb® differ from Ultra-Clear®?A: Both are granular attapulgite-based filtration media, but they are produced by different manufacturers and have different published properties, quality specifications, and application positioning. Product selection should be based on the process, contaminants, equipment, and validation requirements. Q: What package sizes are available?A: Standard options include a 25 kg (55 lb) box, a 100 kg (220 lb) pallet containing four boxes, and a 908 kg (2,000 lb) production pallet. Q: Can I request a Certificate of Analysis?A: Yes. Lot-specific Certificates of Analysis are available upon request for qualifying orders and shipped production lots. Q: How quickly can Microsorb® ship?A: Stocked formats typically ship within 1–2 business days, subject to inventory, freight scheduling, and final order confirmation.
