Will my Doulton filter element remove Pseudomonas aeroginosa?
Pseudomonas aeroginosa is a potential coloniser of water system networks and is similar in size to E-coli. FICL candles should therefore, in theory, show similar reduction efficiency for Pseudomonas aeroginosa and E-coli. However, since the organism is rapid growing and may recover quickly. Without physically testing FICL ceramic filters with this type or organism, it is impossible to predict a performance claim. FICL are not prepared to attempt a prediction of performance, since the filters do not provide 100% barrier to E-coli, a limited number of cells may pass through the filter which, unlike E-coli may form colonies down stream of the filter. It would be more suitable to combine filtration with a disinfection stage to ensure removal of Pseudomonas aeroginosa.
