In the receiver pan (i.e. the fraction < 100 µm), no test substance was collected.

Conclusions:
Particle size distribution of Vinasses by dry sieving was successfully performed. In the receiver pan (i.e. the fraction < 100 µm), no test substance was collected.

Description of key information

Liquid Vinasses:
not applicable
Solid Vinasses:
Particle size distribution at different passages:
< 500 µm: 0%
500 - 2000 µm: 0.2%
> 2000 µm: 99.8%

Additional information

Solid Vinasses:

Method: CIPAC, Physico-chemical Methods for Technical and Formulated Pesticides, MT 59: "Sieve Analysis".

 

The particle size distribution (granulometry) study does not need to be performed for Vinasses, which are marketed or used only in forms of suspension (aqueous solution) and pastes.
