EMFs for treatment of biofilms in public water systems

[Guest guest]

www.huntertechnologies.com.au/scientificstudies/New%20AwwA.pdf " A technology that may help solve many problems relating to water treatment is being investigated at Griffith University in relation to Cryptosporidium oocysts in water and biofilms that build up on pipes carrying water. This technology uses low frequency sound waves and electromagnetic fields. "

  " Electrochemical, magnetic (Belova, 1972; Demchuck et al., 982) and sonic (Christian, et al., 1998; Ma and Lin, 1998) treatment for removing chemical contaminants from water and preventing scale build up in pipes (Baker and Judd, 1996), has been investigated for a number of years. The effect of electro-magnetic fields on biological cells has also been reasonably well studied (Goldsworthy, et al., 1999; Mahawaorasilpa, et al., 1996; Schoenbach, et al., 1997). Despite a plethora of both scientific and anecdotal evidence suggesting that electro-assisted treatment has merit, the industry and the scientific community remain skeptical of such technology. Probably because the evidence both supports and disputes the beneficial effects of the technology that manufacturers often claim. Despite this skepticism, a thriving

industry is growing in the manufacturing and application of electro/magnetic devices. It is of paramount importance that science is involved in the development of these treatment technologies. It is important to ensure that the mode of action on different biological cells and chemical components in water is thoroughly understood. "
