Alfred M. Moen (27 December 1916 – 17 April 2001) was an American inventor and founder of Moen Incorporated.He invented the single-handed mixing faucet.In 1959 Fortune magazine listed the Moen "one-handle mixing faucet", along with inventions such as Henry Ford's Model T and Benjamin Franklin's Franklin stove, as one of the top 100 best-designed mass-produced products, the result of a survey ...
The screen in the aerator, he said, could trap lead particles; if so, water drawn for testing would not reflect the full lead exposure experienced by people drinking from the faucet under normal use. [18] In 2007, the University of North Carolina at Chapel Hill hired Edwards to investigate water-quality problems in three buildings.
When an aerator is added to the faucet (or fluid stream), there is a region of high pressure created behind the aerator. Because of the higher pressure behind the aerator and the low pressure in front of it (outside the faucet), due to Bernoulli's principle there is an increase in velocity of the fluid flow.
An aerator spreads the water flow into many small droplets. In sanitary settings such as hospitals or laboratories "laminar flow devices" are used in place of aerators. Laminar flow devices restrict flow and direct the water into a smooth stream without introducing the surrounding air which could contain hazardous bacteria or particles.
The effectiveness of a surface aerator is limited to a small area as they are unable to add circulation or oxygen to much more than a 3-metre radius. This circulation and oxygenating is then limited to the uppermost portion of the water column, often leaving the bottom portions unaffected. Low speed surface aerators can also be installed on floats.
Jet aerators are easily configured into any basin geometry including circular, rectangular, looped reactors and sloped wall basins. Jet aerators are ideally suited for deep tank processes. The jet oxidation ditch is an example of technology innovation where the combination of a deeper basin design, bottom to top mixing and conservation of ...
