Abstract : The feasibility of detecting microorganisms in water by using declining flow rates through a membrane filter has been determined. Results obtained indicate that microorganisms in water may be detected by the decrease in flow rates through a sub-micron filter used under standard conditions. Decreases in flow rates shown by bacteria are appreciably greater than those caused by inert materials. Results from this study indicate that differential filtration rates may be used as a device for the physical detection of microorganisms in potable water in space system water supplies. (Author)
