In a series of tests using the MS-2 coliphage as a surrogate for enteric viruses, CoMag™ has demonstrated the consistent ability to achieve near four log removal of submicron-sized pathogens – like viruses - from water. Given that the capsid diameter of MS-2 is 0.026 microns, these tests suggest that CoMag™ is also very effective in removing such common pathogens as Cryptosporidium parvum (3-5 microns) or Giardia lamblia (~15 microns).
Based on this preliminary test program the CoMag™ process should be expected to be able to remove more than 99.00% of coliphages present in the water treated. It can be safely assumed that similar results should be obtained when processing drinking water.
The ability to remove 26 nm particles further indicates that CoMag™’s particulate removal process is fully comparable to the lower end of the “Microfiltration” particle size spectrum.
All samples are from the Concord WWTP secondary effluent spiked with MS-2 to achieve the Plaque Forming Units per unit volume (PFU/mL) shown as “Before Treatment”.
