Import Diatomite Filter Aid — Buy in Bulk from Supplier in China

Diatomite filter aid from Qingdao Jiameng Import & Export Co., Ltd. is a calcined fine powder with a pink hue, derived from fossilized diatom shells. It has a specific gravity of 2.3 g/cm³ and an oil absorption range of 100 to 150 percent by weight. The product is processed to remove impurities and is designed for high-flow filtration applications where clarity and particle retention are critical. It is not a raw diatomite but a thermally treated form, which enhances porosity and structural stability under pressure.

This material is typically classified as a Class B diatomite, with particle sizes averaging between 5 and 20 micrometers. The moisture content is kept below 5 percent, consistent with industry standards for filter aids used in beverage and chemical processing. The pink color indicates the presence of iron oxide, which is common in calcined diatomite sourced from marine deposits. Unlike raw diatomite, this product has low soluble silica content, reducing the risk of contamination in sensitive applications.

It is commonly used in brewing, winemaking, pharmaceutical filtration, and industrial wastewater treatment. Buyers include breweries in Southeast Asia, food processors in the Middle East, and chemical manufacturers requiring consistent suspended solids removal. Packaging is in 25 kg multi-wall paper bags, with bulk options available. The supplier confirms standard export packaging but does not specify minimum order quantities or lead times; buyers should confirm these directly before placing orders.

Qingdao Jiameng Import & Export Co., Ltd. is based in Jiaozhou, Shandong Province, with a registered address at 16-1 Commerce Net Area No. 48, Luzhou Road. The supplier is categorized as an imported trader with harbor-level trust signals, indicating active export operations and customs clearance experience. The listing does not state factory ownership, production capacity, or years in business, and there is no verified response rate or average reply time provided.

The company sources and exports diatomite filter aid under the product code jm-dewx020, with no indication of in-house processing or laboratory testing capabilities. It does not claim certifications such as ISO, FDA, or NSF. Buyers should treat this as a trading entity with access to diatomite supply chains in China, not as a manufacturer. Verification of product consistency and origin should be requested prior to order placement.
