The use of membrane filtration to remove contaminants has been growing since the early 1990s. It is now considered one of the most advanced and state-of-the-art methods for removing impurities from water, as well as many commercial food and beverage products.
Membrane filtration is achieved by applying a driving force to a thin, semi-permeable layer of material; this process removes particulates, bacteria, micro-organisms, and organic matter. Filtration provides excellent benefits for the food and beverage industry, aiding in the concentration, clarification, desalting, and purification of potable liquids and food items.
Advantages of Membrane Filtration
Recent advances in membrane manufacturing technology have underscored the method’s efficiency. When compared to conventional decontamination methods such as thermal filtration, membrane filtration offers enhanced benefits, including:
- More Effective Contaminant Removal — Smaller pore membrane technology has been tested to remove contaminants at rates up to 99.9999%.
- Multiple Filtration Ratings — Contaminants are extremely precisely filtered with settings ranging from microfiltration to reverse osmosis.
- Reliability — Membrane filtration products meet industry standards and government regulations for reliable and consistent purity.
- Reduced Environmental Impact — The process requires lower energy supplies than conventional methods while typically taking up significantly less physical space.
- Increased Efficiency — Ratios of liquid produced versus liquid fed average close to 98%.
- Easy Operation — While traditional contamination removal technologies require constant adjustment and monitoring, membrane filtration systems provide highly automated controls that offer smooth operation and require less operator interaction.
The food and beverage industry utilizes membrane filtration to remove unwanted elements while maintaining the taste and integrity of products, such as fruit and vegetable juices, milk, non-alcoholic beers, and water. Food items like cheese, ice cream, and butter also use microfiltration to remove impurities while maintaining essential nutrients.
