Beer filtration

We offer smart mineral solutions for improved filtration and stabilization efficiency for brewers.

Innovative filter aids and beer stabilizers

We are the leading producer of Diatomaceous Earth (DE) and perlite filter aids for beer with over 100 years experience in research, innovation and quality systems. 

Over the past decade, we have led the way in beer filtration. Working closely with our brewer customers, we have researched every aspect of the filter aid and beer interface – from beer chemistry to DE particle size, shape and density. 

This collaboration has produced innovations such as the Celite Cynergy® range of diatomite-based beer stabilizing adsorbents. 

We focus our research on innovations that reduce DE usage and provide environmentally friendly filtration technologies. Working with one brewery at a time, through filtration audits, we achieve reductions in the amount of filter aid needed, whilst at the same time looking at improving filtered beer quality.

Our Celite Cynergy range is the first system to combine filtration and cold stabilization for better efficiency. Our Celite Cynergy range combines all the benefits of the Celite brewing filtration grades plus added stabilization. It filters just like diatomaceous earth (kieselguhr) and cold stabilizes like a silica gel, but performs much better, resulting in decreased powder dosing rates, reduced waste and less filter cleaning. This increases your beer production without expanding your filtration and stabilization equipment. 

Celite brewing grades have a lower level of Beer-Soluble Iron (BSI) compared to standard DE grades. Cutting down on BSI will improve the flavour and colloidal stability of your beer, and Celite brewing grades can also offer exceptional bright beer clarity.

Harborlite® and Europerl® perlite filter aid grades can be used as an alternative to DE in the precoat and sometimes even the body feed, and offer a high solids holding capacity. Harborlite and Europerl filter aids are available in a wide range of permeability to allow you to achieve your desired clarity and throughput specifications.

Our Celite Fibra-Cel cellulose-based range is ideal for rapid pre-coating, especially with old or damaged screens. The Celite Fibra-Cel range offers a stable cake formation and can protect the filter cake against unwanted pressure shocks. It also aids filter cake release during filter wash offs.  

Whatever processes you’re employing or the challenges you’re facing, we have the expertise and the mineral solutions to help. Contact us to find the right product for your requirements.
