Water testing for

The effective saturation depth,, represents the depth of water under which the total pressure (hydrostatic plus atmospheric) would produce a saturation concentration equal to for water ia contact with air at 100% relative humidity. This can be calculated usiag the above equation, based on a spatial average value of T, measured by a clean water test. For design purposes,, can be estimated from clean water test results on similar systems, and it can range from 5 to 50% of tank Hquid depth. Effective depth values for coarse bubble diffused air, fine bubble diffused air, and low speed surface aerators are 26 to 34%, 21 to 44%, and 5 to 7%, of the Hquid depth, respectively. 

Make one or more Endo or eosin methylene blue plates from the tube which, after 48 hours incubation, showB gas formation from the emallest amount of water tested. (For example, if the water has been tested in amounts to 10 cc., 1 cc., and 0.1 cc and gas is formed in 10 cc. and 1 cc. not in 0.1 cc., the test need be confirmed only in the 1 cc. amount)... 

Tests for Pseudomonas aeruginosa are not used in the standard tests for the examination of water. Tests for this organism are frequently used by manufacturers of food, drinks, and pharmaceuticals. Pseudomonas is a Gram-negative rod, giving positive catalase and oxidase tests and producing pigmentation. 

In his 1756 paper he refers to the formation of a film on lime water exposed to the atmosphere by fixed air, and the milkiness produced in lime water by fixed air in a carbonate, but the lime water test for the gas is first mentioned in his lectures as discovered in 1756 (1757 in text, probably in error).
