Beverage Filtration

Soft drinks refer to beverage products with ethanol content not exceeding 0.5% by mass fraction, which are packaged in quantitative packaging for direct drinking or drinking by mixing with water, excluding drinking medicine. Their main raw materials are drinking water or mineral water, fruit juice, vegetable juice or plant roots, stems, leaves, flowers and extracts of fruits, some also contain sweeteners, sour agents, flavors, spices, food coloring, emulsifiers, foaming agents, stabilizers, preservatives and other food additives.
The production of soft drinks requires clarification and multiple precision filtration to improve the taste, and at the same time bring a better visual experience. The sterilization, particulate impurity interception and accurate clarification involved in the process will have an impact on the final product quality, so it is very important to choose the right filter product. Taking

carbonated beverage as an example, the main filtration sites of the whole process are as follows:

1. Security filtration: pre-filtration before reverse osmosis to protect RO membrane
2. Sterilization pre-filtration: remove large particles and other impurities, protect the life of downstream sterilization filtration
3. Sterilization filtration: remove microorganisms such as bacteria and eggs in water to ensure long-term preservation quality of water
4. Gas sterilization filtration (air, respirator): for compress air or other protective gases, remove moisture, particles and bacteria
