Membrane filters are used in water and wastewater treatment, chemical processing, medical and pharmaceutical, food and beverage production, and various other industries. Use of the technology in all of these sectors is currently seeing growth, which in turn is driving the development of cheaper and more efficient membrane filtration apparatus.
The first membrane filters were based on the osmosis principle, where water is transferred from a weak solution to a strong one through a membrane. Since then, more robust and efficient processes have been conceived, including membrane distillation, gas filtration, and electrodialysis. For companies using membrane filters in their processes, keeping the related equipment maintained to a high standard is crucial to delivering the desired results. Such maintenance is concerned with, not only keeping the equipment operational, but also in guaranteeing its effectiveness; in this case, that means being able to test just how well a filter is working, and ensuring the results are within acceptable parameters.
It is for this purpose that methods for the integrity testing of membrane filters have been developed. Sensitive diagnostic equipment is needed, as the goal is not only to check that filtration is occurring, but also to be able to confirm that filters rated at 0.2, 0.45, 0.65 etc. are actually performing as intended. Due to misapprehensions about the technology, it has sometimes been found that filters sold for these systems are not actually membrane filters at all! What is obviously needed for the integrity testing of membrane filters, then, is a service with a good level of knowledge and experience in the industry, and the equipment to specifically test and rate filters under lab conditions.
This is where CFS Filtration come in. As far as we know, we are the only company in the UK offering this service to all industries at this level. By using the latest programmable integrity testing gear, we can test any membrane filter from any manufacturer, while our extensive experience in supplying filters will allow us to spot any item which is not what it claims to be. Integrity testing of membrane filters can be applied to brand new items to test their suitability for a particular application, or to used filters to check that their performance has not been compromised. If a replacement filter is required, we can provide new ones at an excellent price, and dispose of the old part if needed.
If your business is providing commodities which are guaranteed to meet a certain specification, it may only take one mistake to ruin an important business relationship and lose you a lot of trade. By ordering integrity testing of membrane filters, it is possible to eliminate one possible flaw in your process, allowing you to trade with confidence. CFS Filtration can perform integrity testing of membrane filters at our lab, or perform the process at your site for an additional charge. We then provide a certificate of integrity to document the results of the test.
