Oxygen is life: it is among the most abundant elements on Earth; it is present in the atmosphere, in the water of seas and oceans, and in vegetation. And in the human body.

In the food industry, oxygen performs several functions including the preservation of food consumed habitually.

In the food and beverage industry, oxygen is also used for:

• Oxygenation in tanks in fish farms
• As ozone, for pest control and sterilization in industrial manufacturing processes

O₂ also serves another important function: it is used in process water treatment and wastewater purification.

From SIAD plants ultra-pure food-grade oxygen

At the plant in Osio Sopra, in the province of Bergamo, the most articulated national facility in the technical gas sector and the largest among SIAD’s production units, the T1000 air fractionation plant provides a production capacity of 1,300 tons per day of O₂. SIAD also produces ultrapure oxygen (grade 6.0): this is obtained through a double distillation plant that receives technical oxygen as a raw material input.
