UK filter manufacturer Amazon Filters, in partnership with a US-based crude oil and natural gas producer has held a series of tests of its recently launched SupaSpun KilBac and SupaGard Kilbac filters to check how well KilBac protects seawater membranes.

Due to the pandemic, which reduced the scope for testing, it is the first time the technology behind KilBac’s meltblown fibre construction has been rigorously examined in real-world rather than laboratory conditions. The tests successfully proved the value of the Kilbac filters in combating biofouling and growth, including algae which can significantly reduce fluid throughput.

KilBac features high-performance antimicrobial and antialgal additives. The underlying technology harnesses micron-sized particles containing active silver, zinc and copper which, combined with a base polymer, combat the growth of bacteria or algae on the filter, extending cartridge life and optimising performance.

Amazon Filters’ managing director, Neil Pizzey said the test results provided compelling evidence that the use of KilBac variant filters in seawater filtration systems can reduce the requirement for changeouts and more than double the service life of cartridges at the prefiltration stage.
