What is to gain by using spiral membrane filtration?

FOR separation processes, membrane filtration has its advantages, and there are several that meet different applications in food and beverage, brewery, agriculture, and other industries. Many companies prefer it for filtering larger sediments because it is a simple technology as compared to other filtration systems.

According to Alfa Laval, which offers different membrane filtration equipment, the technology can allow users to cut a fraction from their production costs. First and foremost, the system is cheaper than other separators. The company points out that its PP spiral membranes can filter a wider area because of its compact design. Among the benefits are reduced consumption of water and chemicals. Since these membranes are durable, they require less maintenance which means less downtime.

Since membrane filtration relies on separating particles based on molecular size, consumers don’t have to invest in additives. Not only does this benefit the user cost-wise, but it ensures him that he is employing clean technology.

The PP spiral membranes are more hygienic than conventional membranes, Alfa Laval said because they can withstand high numbers of Cleaning-in-Place (CIP) cycles, hot cleaning temperatures and high pH levels.

When it comes to performance, membrane filtration systems are designed to carry out separation of matter with different viscosities, including high-viscosity products that can be difficult to process. Those from Alfa Laval can be customized to meet any process needs and are expandable if production requirements increase.

Finally, there is the issue of consistent pressure, the lack of which will diminish that efficiency of membrane filtration systems. Hygienic high-pressure pumps are used to make the feed stream flow across the surface of the membrane and through its microscopic pores at a consistent rate, boosting both reliability and efficiency.  This ensures continued efficient operation.
