Jewell Water Filter
A Jewell water filter was a system of sand filters for filtering and treating water for drinking purposes that made use of gravity to allow water to percolate through a column of sand inside cylindrical cisterns that was widely used in the early twentieth century. They are named after Omar Hestrian Jewell (1 July 1842 - 19 June 1931) established Jewell Pure Water Company in Chicago in 1890 and managed later by two of his sons. Jewell water filters were used in many city water supply systems across the world and modified versions continue to be in use. History Slow sand filters were introduced at a point when the nature of disease causing organisms in typhoid and cholera had been established. Omar Jewell was a mechanical engineer who designed farm equipment and he took an interest in solving some of the problems involved in the filtration of water and established the O.H.Jewell Filter Company and was financed by Chicago-based waterwork dealers ''James B. Clow and Sons''. Omar's s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sand Filter
Sand filters are used as a step in the water treatment process of water purification. There are three main types; rapid (gravity) sand filters, upward flow sand filters and slow sand filters. All three methods are used extensively in the water industry throughout the world. The first two require the use of flocculant chemicals to work effectively while slow sand filters can produce very high quality water with pathogens removal from 90% to >99% (depending on the strains), taste and odour without the need for chemical aids. Sand filters can, apart from being used in water treatment plants, be used for water purification in singular households as they use materials which are available for most people. History The history of separation techniques reaches far back, as filter materials were already in use during ancient periods. Rushes and genista plants were used to fill sieving vessels that separated solid and liquid materials. The Egyptians also used porous clay vessels to filte ...

Water Filter
A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents, for purposes such as: providing agricultural irrigation, accessible drinking water, public and private aquariums, and the safe use of ponds and swimming pools. Methods of filtration Filters use sieve, sieving, adsorption, ion exchanges, biofilms and other processes to remove unwanted substances from water. Unlike a sieve or Screen filter, screen, a filter can potentially remove particles much smaller than the holes through which its water passes, such as Nitrates or germs like ''Cryptosporidium.'' Among the methods of filtration, notable examples are Sedimentation (water treatment), sedimentation, used to separate hard and suspended solids from water and Activated Charcoal, activated charcoal treatment, where the boiled water is poured through a piece of cloth to trap undesired residuals.

Drinking Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Typhoid
Typhoid fever, also known as typhoid, is a disease caused by '' Salmonella'' serotype Typhi bacteria. Symptoms vary from mild to severe, and usually begin six to 30 days after exposure. Often there is a gradual onset of a high fever over several days. This is commonly accompanied by weakness, abdominal pain, constipation, headaches, and mild vomiting. Some people develop a skin rash with rose colored spots. In severe cases, people may experience confusion. Without treatment, symptoms may last weeks or months. Diarrhea may be severe, but is uncommon. Other people may carry the bacterium without being affected, but they are still able to spread the disease. Typhoid fever is a type of enteric fever, along with paratyphoid fever. ''S. enterica'' Typhi is believed to infect and replicate only within humans. Typhoid is caused by the bacterium ''Salmonella enterica'' subsp. ''enterica'' serovar Typhi growing in the intestines, peyers patches, mesenteric lymph nodes, spleen, liver, ...

Cholera
Cholera is an infection of the small intestine by some strains of the bacterium ''Vibrio cholerae''. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance. This may result in sunken eyes, cold skin, decreased skin elasticity, and wrinkling of the hands and feet. Dehydration can cause the skin to turn bluish. Symptoms start two hours to five days after exposure. Cholera is caused by a number of types of ''Vibrio cholerae'', with some types producing more severe disease than others. It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. Undercooked shellfish is a common source. Humans are the only known host for the bacteria. Risk factors for the disease include poor sanitation, not enough clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

John Wesley Hyatt
John Wesley Hyatt (November 28, 1837 – May 10, 1920) was an American inventor. He is mainly known for simplifying the production of celluloid. Hyatt, a Perkin Medal recipient, is included in the National Inventors Hall of Fame. He had nearly 238 patents to his credit, including improvements to sugar cane mills and water filtration devices. Biography Hyatt was born in Starkey, New York, and began working as a printer when he was 16. Later, he invented plastic, receiving several hundred patents. Among the most well-known of his inventions was that of a substitute for ivory to produce billiard balls. An award of $10,000 had been instituted by Michael Phelan in 1863 due to the cost of ivory and concerns on its shortage. Aided by his brother Isaiah, Hyatt experimented with Parkesine, a hardened form of nitrocellulose. Parkesine had been invented by the Englishman Alexander Parkes in 1862, and is considered the first true plastic, although it was not a success as a commercial or i ...
