Welcome to Imerys Performance Minerals

Beer Filtration

BEER FILTRATION Innovative mineral solutions for improved filtration and beer stabilization efficiency

Imerys is leading producer of diatomaceous earth (DE, kieselguhr) and perlite filter aids for beer with over a hundred years’ experience in research, innovation and quality systems.

Over the last decade, Imerys has led the way in beer filtration. Working closely with 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. 

Innovative filter aids and stabilizing filter aids for beer production

We focus our research on innovations which reduce DE usage and provide environment-friendly filtration technologies. Working with one brewery at a time, through filtration audits, we achieve reductions in the amount of filter aid needed.

Celite Cynergy® engineered DE

Celite Cynergy® is the first system to combine filtration and cold stabilization for better efficiency. Celite Cynergy®:

  • Combines all the benefits of the Celite® brewing grades plus stabilization 
  • Filters like diatomaceous earth (kieselguhr) and cold stabilizes like silica gel, but performs much better
  • Results in decreased powder dosing rates, reduced waste and less filter cleaning, thereby increasing beer production without expanding filtration and stabilization equipment

Celite® brewing grades DE

Celite® brewing  grades have a lower level of beer soluble iron (BSI) compared to standard DE grades—BSI has a negative effect on beer flavor and colloidal stability. Celite brewing grades can offer exceptional bright beer clarity.

Harborlite® perlite precoat grades

Harbolite® perlite filter aid grades can be used as an alternative to DE in the precoat and body feed and offer a high solids holding capacity. Harborlite filter aids are offered in a wide range of permeability to allow customers to achieve their desired clarity and throughput specifications.

Celite Fibra-Cel®

Celite Fibra-Cel® is a cellulose based product ideal for rapid pre-coating, especially with old/damaged screens. Celite Fibra-Cel® offers a stable cake formation and can protect the filter cake against unwanted pressure shocks. It aids filter cake release during filter sluicing.  

Application specific benefits

  • Low beer soluble iron (BSI)
  • Stabilizing filter aids to prevent chill haze
  • Increased production efficiency
  • Longer filter cycles
