METHOD AND APPARATUS FOR DETECTION AND TREATMENT OF E. COLI IN WATER

摘要

A water treatment system uses a process of 'fishing, trapping and killing' to treat Escherichiacoli (E. coli). D-glucose, adsorbed onto paper strips may facilitate the 'fishing' of E. coli. The porous nature of the paper strip facilitates the 'trapping' of the bacteria. A portion of the strip containing Moringa oleifera cationic protein (MOCP) can 'kill' the 'trapped' E. coli through prolonged contact. A similar strip-based device may also be used for detecting E. coli in water. One end of the strip is coated D-glucose (dextrose) 'fish' for E. coli. The E. coli in the paper strip will migrate towards the other end of the paper strip by capillary action. The E. coli bacteria will concentrate near the opposite end of the paper strip containing a hydrophobic barrier and react with the chemicals added to the strip to produce a visually observable colour change to indicate presence of E. coli.
