Pure to the last bubble.
On a carbonated-beverage line the CO₂, the sterile air and the water all go straight into the drink — every one is a contamination route. We supply the filters that close them all.
Off-taste · cloudy batch · recalled pallets · a reputation that took decades to build.
A carbonated soft drink is mostly treated water, sugar syrup and dissolved CO₂ — and every one of those streams is filtered into the finished product. The carbonation gas goes straight into the can. The sterile air rinses the bottle. The water is the largest single ingredient. Each high-sugar tank breathes room air, and the syrup is the last liquid before fill.
Ultrafilter has supplied filtration to beverage lines — P-SRF for carbonation CO₂ and sterile air at the rinser and filler, PF-PES membranes for treated process and ingredient water, PF-PP food-contact pre-filters for incoming and rinse water, and P-BE and PF-PT breathers for concentrate and sugar tanks. FDA 21 CFR per product DoC; EC 1935/2004 for P-SRF elements. Every element ships with its datasheet and food-contact Declaration of Conformity; sterile elements also with integrity-test record and validation guide.
Each family covers a duty on the soft-drink line. Each ships with its datasheet and food-contact Declaration of Conformity; sterile elements also with integrity-test record and validation guide.
Sterile air and carbonation CO₂ at the rinser, filler and gas store. 0.2 µm absolute, min. 100 sterilisation cycles.
PES membrane for treated process and ingredient water. EC directives for food contact.
Sterile tank vent for concentrate, sweetener and sugar tanks — 99.99998 % related to 0.2 µm, min. 100 sterilisation cycles.
Hydrophobic PTFE membrane breather, 0.2 µm, as the alternative sterile vent on concentrate and syrup tanks. Up to 100 forward steam cycles of 30 min at 135 °C.
All-polypropylene food-contact pre-filter for incoming and rinse water.
Every element carries the paperwork your QA and production teams need before it ever contacts your process gas or product stream.
Send us a P&ID, a flow rate, or just the duty — carbonation CO₂, sterile rinser air, treated water, PES membranes or tank breathers. We size the train and ship the documentation: datasheet and food-contact DoC, plus integrity-test record and validation guide for sterile elements.
