Perlite filter aids

Perlite filter aids

Imerys supplies an extensive range of perlite filter aids to suit all food and beverage filtration capabilities.

What is perlite?

Perlite is made from soft alumino silicate rock that expands rapidly when heated as the water in its structure turns to steam. This expanded structure is then milled to the desired particle size distribution to make various grades of filter aid products.

Imerys produces high permeability grades for high solid content or ‘rough’ filtration; low permeability grades for low solid or high clarity ‘fine’ filtration. All our perlites are inert and provide a natural and sustainable filtration medium.

Perlite filter aids are very light in density, making them exceptional in their capacity to retain large quantities of suspended solids in a filter cake without blocking.

A wide range of products to match different filtration capabilities

Imerys offers a wide range of different perlite filter aids to cover the full range of filtration capabilities.

  • Imerys Europerl® and Harbolite® perlite filter aids provide superior filtration performance in beer, juices, sugar syrups, edible oils, alginates, gelatin and hydrocolloid. Multiple grades ensure optimal filtration performance and the flexibility required when filtering natural raw materials where quality can vary with harvest.
  • Our high density perlite filters Europerl® HD and Harbolite® HD have been designed to reduce product losses in high value Rotovac filtration applications where they provide easy and fast pre-coating, reduced unit consumption and high flow rates. They are particularly valuable in sweetener filtration.
  • The ImerVin range of bespoke wine filter aids have been developed hand in hand with oenologists.
    Our most recent innovation, ImerVin Efficace
    is a high performance filter aid designed for the filtration of grape juice musts. It is proven to be effective at lower dosing rates, improves filtration capacity and reduces juice losses in the filter cake.
  • ImerVin 800 and ImerVin 1200S are high efficacy perlites engineered to give higher filtration capacity at lower powder dosing rates.

All our filtration products are FCC approved and manufactured in GMP facilities.
