George W. Fuller
George Warren Fuller (December 21, 1868 – June 15, 1934) was an American sanitary engineer who was also trained in bacteriology and chemistry. His career extended from 1890 to 1934 and he was responsible for important innovations in water and wastewater treatment. He designed and built the first modern water filtration plant, and he designed and built the first chlorination system that disinfected a U.S. drinking water supply. In addition, he performed groundbreaking engineering work on sewage treatment facilities in the U.S. He was President of both the American Water Works Association and the American Public Health Association, and he was recognized internationally as an expert civil and sanitary engineer. Early life and education George W. Fuller was born in Franklin, Massachusetts in 1868. After his primary and secondary education, he was accepted at the Massachusetts Institute of Technology at the age of 16. He deferred his attendance at MIT for one year (beginning 1 ...

Franklin, Massachusetts
The Town of Franklin is a city in Norfolk County, Massachusetts, United States. Franklin is one of thirteen Massachusetts municipalities that have applied for, and been granted, city forms of government but wish to retain "The town of" in their official names.

Slow Sand Filters
Slow sand filters are used in water purification for treating raw water to produce a potable product. They are typically deep, can be rectangular or cylindrical in cross section and are used primarily to treat surface water. The length and breadth of the tanks are determined by the flow rate desired by the filters, which typically have a loading rate of per square metre per hour. Slow sand filters differ from all other filters used to treat drinking water in that they work by using a complex biological film that grows naturally on the surface of the sand. The sand itself does not perform any filtration function but simply acts as a substrate, unlike its counterparts for ultraviolet and pressurized treatments. Although they are often preferred technology in many developing countries because of their low energy requirements and robust performance, they are also used to treat water in some developed countries, such as the UK, where they are used to treat water supplied to London. ...

Imhoff Tank
The Imhoff tank, named for German engineer Karl Imhoff (1876–1965), is a chamber suitable for the reception and processing of sewage. It may be used for the clarification of sewage by simple settling and sedimentation, along with anaerobic digestion of the extracted sludge. It consists of an upper chamber in which sedimentation takes place, from which collected solids slide down inclined bottom slopes to an entrance into a lower chamber in which the sludge is collected and digested. The two chambers are otherwise unconnected, with the more liquid sewage flowing only through the upper sedimentation chamber and only a slow flow of sludge in the lower digestion chamber. The lower chamber requires separate biogas vents and pipes for the removal of digested sludge, typically after 6–9 months of digestion. The Imhoff tank is in effect a two-story septic tank and retains the septic tank's simplicity while eliminating many of its drawbacks, which largely result from the mixing of fres ...

According to both the Bible and the Quran, Moses was the leader of the Israelites and lawgiver to whom the authorship, or "acquisition from heaven", of the Torah (the first five books of the Bible) is attributed. According to the Book of Exodus, Moses was born in a time when his people, the Israelites, an enslaved minority, were increasing in population and, as a result, the Egyptian Pharaoh worried that they might ally themselves with Egypt's enemies. Moses' Hebrew mother, Jochebed, secretly hid him when Pharaoh ordered all newborn Hebrew boys to be killed in order to reduce the population of ...

Calcium Hypochlorite
Calcium hypochlorite is an inorganic compound with formula Ca(OCl)2. It is the main active ingredient of commercial products called bleaching powder, chlorine powder, or chlorinated lime, used for water treatment and as a bleaching agent. This compound is relatively stable and has greater available chlorine than sodium hypochlorite. It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air. History Charles Tennant and Charles Macintosh developed an industrial process for the manufacture of Chloride of Lime in the late 18th Century. It was patented in 1799 and used heavily during World War I for disinfecting the trenches and wounds. Uses Sanitation Calcium hypochlorite is commonly used to sanitize public swimming pools and disinfect drinking water. Generally the commercial substances are sold with a purity of 65% to 73% with other chemicals present, such as calcium chloride and calcium carb ...

Rockaway River
The Rockaway River is a tributary of the Passaic River, approximately 35 mi (56 km) long, in northern New Jersey in the United States. The upper course of the river flows through a wooded mountainous valley, whereas the lower course flows through the populated New Jersey suburbs and former industrial area west of New York City. It drains an area of approximately 130 sq mi (340 km²). It rises in the Oak Ridge neighborhood of Jefferson Township. It flows SSW, in a direct course between in the valley between the mountain ridges. Northeast of Wharton it emerges from the mountains and flows generally east in a meandering course, past Wharton, Dover (where it enters a concrete channel), Rockaway, Denville and Boonton, where it passes through the Boonton Gorge. The gorge begins with the impressive 25 foot Boonton Falls. It continues for a little over 1 mile (1.6 km) dropping around through nearly continuous class 3 and 4 whitewater. On the south s ...

John L
John Lasarus Williams (29 October 1924 – 15 June 2004), known as John L, was a Welsh nationalist activist. Williams was born in Llangoed on Anglesey, but lived most of his life in nearby Llanfairpwllgwyngyll. In his youth, he was a keen footballer, and he also worked as a teacher. His activism started when he campaigned against the refusal of Brewer Spinks, an employer in Blaenau Ffestiniog, to permit his staff to speak Welsh. This inspired him to become a founder of Undeb y Gymraeg Fyw, and through this organisation was the main organiser of ''Sioe Gymraeg y Borth'' (the Welsh show for Menai Bridge using the colloquial form of its Welsh name).Colli John L Williams , '''', 15 June ...

Typhoid Stats
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, ga ...

Little Falls, New Jersey
Little Falls is a township in Passaic County, New Jersey, United States. The township was named for a waterfall on the Passaic River at a dam near Beattie Mill. As of the 2020 census, the township's population was 13,360 reflecting a decrease of 1,072 (7.4%) from the 14,432 counted in the 2010 Census, which had in turn increased by 3,577 (33.0%) from the 10,855 counted in the 2000 Census. History Little Falls traces its first European settlement to 1711 when seven Bergen Dutch settlers banded together to begin farming. The Speer Homestead dates from (and may have originally been built in 1680). The Morris Canal, once an important artery of trade and transportation until 1925 between the Delaware and Hudson rivers, wound its way through the township and vestiges of it still remain, some parts of which are a greenway. Little Falls was incorporated as a township by an act of the New Jersey Legislature on April 2, 1868, from portions of Acquackanonk Township. On March 25 ...
