Water acts as a vehicle for pathogenic agents and microorganisms such as Legionella spp which develop in hot water systems, or bacteria that thrive in stagnant water (e.g. deadlegs and tap aerators) such as Pseudomonas aeruginosa.
Developed in the 1970s, membrane technology is widely used within the water treatment industry for water purification. Delabie uses hollow fibre membrane filtration for its range of BIOFIL microfilters.
Each BIOFIL filter has an integrated polyethylene hollow fibre membrane, with a filtration threshold of 0.2 microns absolute-rated. The membrane has multiple pores, varying in size from 0.01-0.2 microns. Water requiring treatment passes through the filter under normal dynamic pressure, and bacteria and any particles in suspension larger than 0.2 microns in size are retained permanently on the membrane’s external surface.
The large filtration surface area – of 1,400 cm2 compared with equivalent point-of-use filters at 500 cm2 – means that larger water volumes can be filtered. The outlet flow rate is also improved, and there is less risk of air-locks. BIOFIL anti- bacterial filters are ‘very compact’, and suitable for all types of mixers and taps.
Delabie offers a complete range of single-use BIOFIL water filters, including cartridges, shower heads, and spouts. BIOFIL antibacterial filters are available in non-sterile versions for up to 62 days’ use, or in sterile versions for up to 31 days’ use. The latter are class IIb medical devices, recommended for use where staff are washing wounds or rinsing invasive medical devices. All filters are subject to numerous quality control checks, and supplied ‘with optimal traceability’.
