QFT - QUALITY FILTRATION TEST

ELECTRONIC TEST FOR THE AUTOMATIC CONTROL OF THE FILTERABILITY
The fouling indices or filterability indices proposed by J. Laurenty, developed by J.J. Descout and his collaborators, and perfected by M. Gaillard, are currently the only parameters that are able to supply a valid evaluation of the filterability of a liquid. In the past, various methods and devices were proposed for the evaluation of these indices. All had various inconveniences, and that is possibly the reason for the numerous failures encountered with the use of these parameters.
The research and many years of experience of Enologica Vason in the field of filtration have permitted the development of what is currently the most advanced system for the evaluation and the control of the filtration quality of liquids, and in particular, clear beverages: the QUALITY FILTRATION TEST®.
The QUALITY FILTRATION TEST® is an instrument that is able to carry out and calculate automatically the Filterability Index, the Modified Filterability Index, and the Maximum Filtrable Volume. The results, highly repeatable because of the high level of standardization offered by the instrument, are displayed on an LED display, and printed on paper. The QFT is applied to the evaluation of the efficiency of the different filtration systems: streaming filtration, layered filtration, tangential flow filtration, and others.

Fouling Index


Knowing the filterability index allows:

- Understanding of the state of the wine to allow the choice of the best filtration system to be adopted
- A review of the results after filtration of wines
- The control of clogging effect of service waters
- A substantial savings, thanks to improved control of all processes of filtration and regeneration of filters


Furthermore the processes of membrane filtration, are characterized by high efficiency in removing the contaminant, but usually by a limited storage capacity of retain matter. Therefore, the presence of solids and colloids in the product to be micro-filtered is often the critical point of this type of technology. In order to optimise the process is however essential that the filterability of the product is such to make its filtration technically and economically viable.

 

The Q.F.T. (the precursor of the most recent version MASTERMIND® QFT) is present since the 90’s in the best wine laboratories in Italy, to secure the membrane processes as required by the procedures validated by certification authorities.
