Examination of Water

Microbiological examination of sebeel water.

Water samples from clay storage jugs ("zeers") located in homes and at public watering stands ("sebeels") at streets, mosques, and schools were examined. Coliforms, fecal coliforms, and fecal streptococci were detected in 100, 69, 88, and 91.56% of the samples, respectively. The general microbiology of the water and some factors affecting microbial load were studied. The predominant bacterial g...

Aminomethanol water elimination: theoretical examination.

The mechanism for the formation of hexamethylenetetraamine predicts the formation of aminomethanol from the addition of ammonia to formaldehyde. This molecule subsequently undergoes unimolecular decomposition to form methanimine and water. Aminomethanol is the predicted precursor to interstellar glycine, and is therefore of great interest for laboratory spectroscopic study, which would serve as...

Standard methods for the examination of water and waste water.

The dilution biochemical oxygen demand (BOD) test has widespread application for design and operation of wastewater treatment processes, evaluating the quality of natural waters, and assessing the effect of wastewater discharges on these waters. While standardization of the BOD-measuring method has become of prime importance in maintaining dependable data acquisition, changes are made as needed...
