Versatile and Efficient Filtration

Dicalite Filter Aid offers high flow rates and efficient solid-liquid separation, making it invaluable in industries such as food processing, pharmaceuticals, and chemicals. Its unique physical structure ensures minimal filtration resistance and high purity, while trace minerals like Al2O3 and MgO are present only as minor components. This filter aid is both tasteless and odorless, ensuring neutrality in sensitive production lines.

Safe, Compliant, and Non-Toxic

Composed largely of silicon dioxide with over 85% purity, Dicalite Filter Aid is non-toxic and meets strict international safety standards-appropriate for both industrial and food applications. It is insoluble in water and organic solvents, guarantees a stable pH range, and will not impart taste or odor, even in delicate processing conditions.

FAQ's of Dicalite Filter Aid:

Q: How does Dicalite Filter Aid work in solid-liquid separation processes?

A: Dicalite Filter Aid functions by forming a porous precoat layer on the filtration surface, capturing suspended solids as liquids pass through. Its particle size distribution (10-100 microns) ensures a high flow rate with minimal pressure drop, making it ideal for efficient solid-liquid separation in various industries.

Q: What are the main benefits of using Dicalite Filter Aid in filtration systems?

A: The primary benefits include high filtration efficiency, low flow resistance, chemical stability across a wide pH range (3-11), and compatibility with both food and industrial processes. Its high oil absorption capacity is especially advantageous in food and beverage applications.

Q: When should Dicalite Filter Aid be used during the filtration process?

A: Dicalite Filter Aid is typically used at the beginning of the filtration cycle to create a precoat on the filter medium. It can also be added continuously during filtration (body feed) to maintain consistent flow and prevent clogging, depending on the nature of the suspension being filtered.

Q: Where is Dicalite Filter Aid commonly applied?

A: This filter aid is widely used in pharmaceuticals, food and beverage processing, chemical manufacturing, and water treatment plants, wherever efficient removal of fine particulate matter from liquids is required.

Q: What packaging options and storage conditions are recommended for Dicalite Filter Aid?

A: Dicalite Filter Aid is available in 15, 25, and 50 kg bags and should be stored in a dry, well-ventilated area to preserve its indefinite shelf life and filtration properties.

Q: Is Dicalite Filter Aid safe for food contact and does it affect the taste or smell of products?

A: Yes, Dicalite Filter Aid meets FDA and EC food safety standards and is both tasteless and odorless, making it suitable for sensitive food and beverage applications without imparting any off-flavors or odors.
