Understanding the importance of filtration

As experts in the ultrasonic cleaning industry, Alphasonics understand the importance of filtration and how to prevent your systems failing.

Filtration is a process used to separate solids from liquids or gases using a medium filter that allows the fluid to pass through, preventing the solid to build up within the cleaning solution. The term “filtration” applies whether the filter is mechanical, biological or physical whereas the fluid that passes through the filter is called “the filtrate.”

In the case of Alphasonics, the filtrate is the water and chemical cleaning solution used during the ultrasonic cleaning stage. The media that requires filtering from the solution in question, can come from printing press parts, Anilox Rolls, fuel nozzles and anything else that requires a 100% precision clean. It can be anything from various types of ink particles, to wood or steel particles. It is vital that the correct filter is selected for the application at hand and luckily, this is something that Alphasonics have over 30 years of experience in.

The filters used in the Alphasonics systems are made up of a polypropylene yarn and core for a higher chemical resistance. These are available in sizes ranging from 5” to 20” with various micron ratings and widths. We also supply Stainless Steel washable filters for all of our standard models that although have a higher initial cost, save time and money going forward as these filters are simply washed in the ultrasonics for re-use.

Not only will a filtration unit on your system save you money by adding longevity to the cleaning solution, it will also give you a lot more consistency and control when cleaning. The result is a high, dirt loading capacity with greater efficiency.

At Alphasonics, we can design our systems to inform you when the filters need to be changed, however, it is always a good idea to introduce this process into your PPM as a filter change schedule.
