- Increase filtration capacity

- Reduce powder usage

- Reduce spent filter cake

- Reduce juice/wine loss

Imerys first began supplying filter aids to the wine making industry more than 50 years ago when large-scale filtration became common practice in commercial wine making. In recent years, there has been very little innovation for filter aid filtration for wine and juice, so we collaborated with oenologists and the French Institut Coopératif du Vin (ICV) to develop a filter aid specifically designed for the optimized filtration of wine musts on rotary drum filters.

Our ImerVin Efficace range was designed to combine the properties delivered by diatomaceous earth and perlite filter aids. We achieved this by carefully selecting the perlite ore raw material, and by making careful adjustments to the production process. The result is a filter aid with permeability, wet density and particle size distribution proven to give improved filtration performance, compared to diatomaceous earth.

The ImerVin Efficace range has been designed to reduce total filtration costs. Compared to current filtration costs (€/hl of juice/wine filtered), the ImerVin Efficace system generates cost savings of 10-15%. This is based on the lower dosing rates (up to 50% lower) required to achieve the same pre-coat size as diatomaceous earth.
