SupaGard Kilbac

In many water-based processes, there can be a persistent problem with microbial contamination and the subsequent biofouling of the filtration system. This can occur on either depth or membrane-based filters. SupaGard KilBac® is a range of nominal rated melt blown depth filters with the addition of KilBac® anti-microbial and anti-algal technology to prevent biofouling on the filtration media.

The Technology

Rather than being based on nano-sized particles whose size and safety have been questioned in the past, our technology utilises micron-sized zeolite structures which are used as a carrier for the anti-microbial agent. By optimising the fibre diameter to the active particle size, we maximise the surface area and hence the efficacy of the anti-microbial to the fluid stream being filtered. KilBac® fibres are blown continuously onto a central support core, with fibre diameters controlled to produce different pore sizes throughout the extrusion process. All the layers are interlinked to offer maximum support while ensuring that the high voids volume is maintained, but with increasing fibre density towards the cartridge central core, resulting in true graded density depth filtration.

Two KilBac® Grades Are Available

• Silver (Ag) / Zinc (Zn) for bacteria control.
• Silver (Ag) / Copper (Cu) for algae control.
