We use this technique for quick clarification of juices or musts. The saturation of the liquid to be clarified with an inert gas (nitrogen) allows the gas micro-bubbles to aggregate with the suspended solids. The saturated liquid tends to separate and stratify very quickly, the cloudy part containing most of the suspended solids tends to rise upwards, precisely due to the presence of the combined gas, leaving the clear liquid in the lower part of the tank.

 

A process that ends in a few hours without the need for cooling energy, unlike a traditional static decantation where the times are longer, the consumption of cooling energy is certainly substantial and the tanks remain occupied to precisely allow the decanting.
