As per the estimation by analysts, the soft drinks consumption across the world will achieve 84.5 l in 2012.
But, the water conservationists do not agree with this, because of the high requirement of water in the manufacturing and bottling methods of soft drinks. Coca-Cola, a soft drink manufacturer, has said that around 1.25 l of water is consumed to manufacture one liter of beverage.
According to UNICEF, safe drinking water is not available for 884 M people in the world and 1.8 B people may experience water scarcity by 2025. Hence, PepsiCo, Coca-Cola and other beverage companies are implementing efficient production processes for water conservation.
Consumption of water can be reduced by decreasing the amount of foam formed during the manufacturing method.
The XIAMETER branded silicone antifoams are specifically designed to avoid the foam problems efficiently and safely in food processing applications. The process foam reduction can increase the productivity, decreases the consumption of water, and saves money by reducing the cost of production.
Silicone antifoams scatter through the liquid film, forming a bubble wall. Lower surface tension in silicone collapses the bubbles, therefore the foam vanishes. These silicone antifoams are effective when used at lower rate, compared to organic antifoaming agents.
Besides soft drink manufacturing, these antifoams are utilized in various beverage and food applications. For instance, silicone antifoams are employed in tank cleaning that is used for process water, to increase the potential in fermentation tanks, foam reduction in the resulting wastewater; during dilution of soft drinks before and in bottling phase.
