Perlite Filter Aid for Edible Oil Neutral pH 25 kg Bags & Bulk Supply
Made from natural perlite ore, our perlite filter aid is processed by crushing, preheating, high-temperature expansion, grinding, classification and impurity removal. It features irregular porous particles, serving as a lightweight, high-performance filter medium. Neutral in pH and insoluble in most organic and inorganic acids, it will not bring odor, pigment or harmful substances to filtrate. Compatible with rotary vacuum filters, filter presses, leaf filters and other equipment, it works for both pre-coating and body feed. It forms stable permeable filter cake to trap suspended solids, colloids and bacteria, preventing filter cloth blinding and boosting throughput.

Appearance features
1. White to off-white powder: Features a uniform, clean white color, ensuring a high-purity final product that does not affect the appearance of the filtrate.
2. Sponge-like porous microstructure: Characterized by a unique honeycomb-like microporous structure with a high pore volume, which serves as the core mechanism for efficiently trapping suspended solids.
3. Lightweight with low bulk density: Possesses an apparent density of approximately 0.10–0.25 g/cm³; its loose, lightweight nature allows for a large filtration surface area per unit of weight.
4. Dry, free-flowing particles: The powder remains loose without clumping, ensuring uniform distribution during pre-coating or direct dosing, as well as consistent metering.
5. Chemically inert and stable: Insoluble in water and resistant to acids and bases (with the exception of hydrofluoric acid); it does not react with the filtrate.
6. Consistent batch-to-batch quality: Produced via standardized calcination and classification processes, ensuring uniform permeability and particle size distribution across different batches.

Advantages
1. Excellent Clarification and Flow Rate: The porous structure strikes an optimal balance between capturing suspended solids and maintaining high filtration flow rates, ensuring both filtrate clarity and production throughput.
2. Chemically Inert—Preserves Filtrate Integrity: Insoluble and non-reactive, it does not leach substances or introduce odors and impurities, thereby maintaining the original composition and flavor profile of the filtrate.
3. Reliable for Food and Beverage Applications: When the appropriate grade is selected, it is suitable for the filtration of food and beverage products—such as beer, wine, fruit juice, and edible oils—ensuring product safety.
4. Cost-Effective Filtration: Lightweight and highly efficient, it provides a large filtration surface area per unit of material used, keeping overall filtration costs manageable.
5. Flexible Supply and Customization: Available in various formats, from small bags and bulk bags to full container loads. We also offer customized product grades, bespoke packaging/labeling, and OEM private-label services.

FAQ
1
What is perlite filter aid made of?
It is produced from perlite ore through crushing, high-temperature expansion, grinding, and classification. It is a processed natural mineral product, not a chemically synthesized material.
2
What does permeability mean, and how should I choose the right grade?
Permeability refers to the rate at which liquid can pass through the filter cake. For high-viscosity liquids or applications requiring high flow rates, choose a coarse-grade, high-permeability product. For applications requiring high clarity and low turbidity, choose a fine-grade, low-permeability product; a combination of coarse and fine grades can also be used.
3
How are "pre-coating" and "body feed" used?
Pre-coating involves establishing an initial layer of filter aid (a "filter cake") on the filter screen or plate using clean water or the filtrate itself. Body feed involves continuously adding filter aid to the liquid being filtered to prevent the filter cake from becoming clogged. These two methods can be used individually or in combination.
4
What should be kept in mind regarding storage?
Store in a dry, well-ventilated warehouse. Keep packaging sealed to prevent moisture absorption and clumping. Avoid storing alongside corrosive chemicals.
5
What are the safety requirements during handling?
As this product is a fine powder, wear a dust mask and protective goggles to avoid inhaling dust. Ensure the work area is well-ventilated, and reseal the packaging promptly after opening.
6
Can perlite filter aid be reused?
Perlite filter aid is a single-use consumable; once the filter cake has trapped impurities, it must be removed and replaced. The spent filter cake should be disposed of in compliance with local regulations.
