EXPLORE OUR INDIVIDUAL FILTER AIDS GRADES
N-10 Grade: The Fine Filtration Specialist
PURPOSE:
The N-10 grade stands as our premier choice for fine filtration needs, particularly excelling in rotary vacuums or filter presses. Its exceptionally small and shattered particles are tailored for intricate applications that demand high precision in separating solids from liquids.
EFFECTIVENESS:
N-10’s fine particles construct a formidable cake layer, transferring the filtration workload from the septum to the perlite filter aid itself. This transition allows for efficient trapping of solids while facilitating the clean passage of liquids. In rotary vacuums, it ensures that solids are effectively separated, leaving behind a clear, purified liquid.

N-15 Grade: The Balanced Blend
PURPOSE:
Our N-15 grade represents a harmonious blend of N-10 and N-20 grades, providing a versatile solution primarily utilized in rotary vacuums. This mixed product is for users seeking a balanced filtration medium that combines the best aspects of both fine and coarse grades.
EFFECTIVENESS:
The key to NC510’s effectiveness is its ability to form a robust cake with ideal integrity. This balance is crucial as every press, application, and operator requires a slightly different approach. The NC510 adapts to these varying needs, offering a tailored cake that maintains its structure while ensuring efficient filtration.

N-20 Grade: The Coarse Clarity Provider
PURPOSE:
As our coarsest filter media, N-20 is predominantly used in filter presses, especially for wastewater applications. This grade is known for its economical value without compromising on performance.
EFFECTIVENESS:
N-20 utilizes its coarser particles to adeptly facilitate the separation process in filter presses. Its structural integrity allows for a pronounced separation of solids and liquids, resulting in clear filtrate and effective solid retention.

Perlite Filter Aid Applications

Beverage Production
Norcal Perlite Filter Aids are widely used in beverage manufacturing to achieve brilliant clarity and consistent quality in juices, wines, beers, and distilled products. The perlite based filtration media efficiently separates solids from liquids, ensuring smooth flow rates and enhanced purity without altering taste, color, or aroma. By improving filter performance and reducing clogging, our filter aids help producers maintain production speed and quality across every batch.

Pharmaceutical Manufacturing
In pharmaceutical and biotechnology applications, Norcal Perlite Filter Aids provide a reliable, inert, and sterile filtration medium that ensures product purity and compliance with strict regulatory standards. The lightweight, chemically stable structure of perlite helps remove fine particulates and unwanted residues from drugs, enzymes, and plasma based formulations, supporting consistent quality control and efficient processing.

Wastewater Treatment
Norcal Perlite Filter Aids play a vital role in industrial and municipal wastewater treatment systems. The coarse perlite particles separate solids and suspended matter from wastewater streams, reducing environmental impact and improving compliance with discharge standards. As an eco friendly, reusable, and non toxic material, perlite filtration media supports sustainability initiatives while minimizing sludge volume and lowering overall disposal costs.

Chemical Processing
In chemical and industrial manufacturing, Norcal Perlite Filter Aids enhance process safety and product consistency by purifying liquids such as resins, solvents, and coatings. Their porous structure enables high throughput and precise solid liquid separation, preventing contamination and maintaining optimal viscosity. This results in cleaner outputs, reduced maintenance downtime, and lower production costs.

Food Processing
Norcal Perlite Filter Aids provide food grade filtration solutions for edible oils, sweeteners, syrups, and plant based extracts. Their inert, non toxic, and odorless composition ensures compliance with FCC and Codex Alimentarius standards while preserving the flavor and nutritional value of food products. The consistent filtration performance helps processors achieve crystal clear results and improved product shelf life.
Perlite Filter Aid Use Cases

Clarifying Drinks and Fermented Beverages
- Beverage plants use perlite filter aids to keep filtration lines running at target flow rates while consistently producing clear juices, wines, beers, and distilled products.
- By forming a porous filter cake, perlite media helps extend filter run time, decrease changeout frequency, and maintain quality specifications without impacting flavor or aroma.

Purifying High Value Pharmaceutical Liquids
- Pharmaceutical and biotech facilities rely on perlite filter aids when filtering sensitive products like enzymes, plasma fractions, and finished drug solutions that must meet strict purity standards.
- Because perlite is inert and sterile, it supports validated processes, helping maintain batch consistency and protecting against particulate contamination.

Managing Solids in Wastewater and Effluent Streams
- In industrial and municipal wastewater systems, perlite filter aids are used to remove suspended solids and fine particles before discharge or further treatment.
- Operators choose perlite media to reduce sludge volume, help meet discharge permits, and support sustainability initiatives with a reusable, non toxic filtration material.

Refining Process Liquids in Chemical Production
- Chemical manufacturers use perlite filter aids when clarifying resins, coatings, solvents, and other process liquids that must stay within tight viscosity and cleanliness ranges.
- The high surface area and permeability of perlite based cakes allow for high throughput filtration while limiting fouling, which helps reduce downtime and maintenance costs.

Cleaning Edible Oils and Food Ingredients
- Food processors apply perlite filter aids to edible oils, sweeteners, syrups, and plant based extracts to achieve the clarity and stability needed for retail ready products.
- The food grade, non toxic nature of perlite media supports regulatory compliance while helping improve shelf life, visual appeal, and overall product quality.
