Ceramic Water Filter
Ceramic water filters (CWF) are an inexpensive and effective type of water filter that rely on the small pore size of ceramic material to filter dirt, debris, and bacteria out of water. This makes them ideal for use in developing countries, and portable ceramic filters are commonly used in backpacking (wilderness), backpacking. Method of action Similar to other methods of filtering water, the filter removes particles larger than the size of the pores in the filter material. Typically bacteria, protozoa, and microbial cysts are removed. However, filters are typically not effective against viruses since they are small enough to pass through to the "clean" side of the filter. Ceramic water filters (CWF) may be treated with silver in a form that will not leach away. The silver helps to kill or incapacitate bacteria and prevent the growth of Mold (fungus), mold and algae in the body of the filter. Ceramic filtration does not remove Chemical substance, chemical contaminants, ''per se'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Appropriate Technology
Appropriate technology is a movement (and its manifestations) encompassing technology, technological choice and application that is small-scale, affordable by its users, labor-intensive, efficient energy use, energy-efficient, environmentally sustainable, and localism (politics), locally autonomous. It was originally articulated as intermediate technology by the economist E. F. Schumacher, Ernst Friedrich "Fritz" Schumacher in his work ''Small Is Beautiful.'' Both Schumacher and many modern-day proponents of appropriate technology also emphasize the technology as People-centered development, people-centered. Appropriate technology has been used to address issues in a wide range of fields. Well-known examples of appropriate technology applications include: bike- and hand-powered water pumps (and other self-powered equipment), the bicycle, the universal nut sheller, self-contained solar lamps and Solar street light, streetlights, and passive solar building designs.

Chamberland Filter
A Chamberland filter, also known as a Pasteur–Chamberland filter, is a porcelain water filter invented by Charles Chamberland in 1884. It was developed after Henry Doulton's ceramic water filter of 1827. It is similar to the Berkefeld filter in principle. Design The filter consists of a permeable unglazed porcelain tube (called bisque) that contains a ring of enameled porcelain through which the inflow pipe fits. The core of the porcelain is made up of a metal pipe with holes through which water flows out and is collected. Inflow is pressurized so filtration occurs under force. There are 13 types: ''L1'' to ''L13''. L1 filters have the coarsest pore size while L13 have the finest. Usefulness The Pasteur-Chamberland filter is as useful as other ceramic and porcelain filters. It is a good bacterial water filter used mainly as a high volume water filter.Textbook of Microbiology by Ananthanarayan and Panikar, The filter works more quickly when the water supplied is und ...

Ron Rivera (public Health)
Ronald Rivera (August 22, 1948 – September 3, 2008) was an American activist of Puerto Rican descent who is best known for promoting an inexpensive ceramic water filter developed in Guatemala by the chemist Fernando Mazariegos and used to treat gray water in impoverished communities and for establishing community-based factories to produce the filters around the world. Early years Rivera was born in the Bronx borough of New York City, of Puerto Rican parents. He was raised in both New York City and Puerto Rico. Rivera graduated from The World University in San Juan, Puerto Rico.

Louis Pasteur
Louis Pasteur (, ; 27 December 1822 – 28 September 1895) was a French chemist, pharmacist, and microbiologist renowned for his discoveries of the principles of vaccination, Fermentation, microbial fermentation, and pasteurization, the last of which was named after him. His research in chemistry led to remarkable breakthroughs in the understanding of the causes and preventions of diseases, which laid down the foundations of hygiene, public health and much of modern medicine. Pasteur's works are credited with saving millions of lives through the developments of vaccines for rabies vaccine, rabies and anthrax vaccine, anthrax. He is regarded as one of the founders of modern bacteriology and has been honored as the "father of bacteriology" and the "father of microbiology" (together with Robert Koch; the latter epithet also attributed to Antonie van Leeuwenhoek). Pasteur was responsible for disproving the doctrine of spontaneous generation. Under the auspices of the French Aca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Doulton
Sir Henry Doulton (25 July 1820 – 18 November 1897) was an English businessman, inventor and manufacturer of pottery, instrumental in developing the ceramics company of Royal Doulton. Life Born in Vauxhall, Henry was the second of the eight children of John Doulton (1793–1873), a pottery manufacturer, and his wife, Jane Duneau, a widow from Bridgnorth in Shropshire. His brother, Frederick Doulton, became Member of Parliament for Lambeth (UK Parliament constituency), Lambeth from 1862 until 1868. His father had become a partner in a pottery business in 1815 but Henry was the most academic of his children. Henry spent two years at the University College School where he developed a love of literature. His father had thought Henry the least likely to join the family business, perhaps being destined for a profession, but in 1835, he joined the firm, as did all his brothers other than Frederick.Clement (2004) One of the first results of his many experiments was the production of go ...

Chlorine
Chlorine is a chemical element; it has Symbol (chemistry), symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidizing agent, oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the revised Electronegativity#Pauling electronegativity, Pauling scale, behind only oxygen and fluorine. Chlorine played an important role in the experiments conducted by medieval Alchemy, alchemists, which commonly involved the heating of chloride Salt (chemistry), salts like ammonium chloride (sal ammoniac) and sodium chloride (common salt), producing various chemical substances containing chlorine such as hydrogen chloride, mercury(II) chloride (corrosive sublimate), and .
