[3] [4] He designed a crude water filter to “purify” the water he used for his patients. Later known as the “Hippocratic sleeve ...
Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.
The Portable Aqua Unit for Lifesaving (short PAUL) is a portable ultrafiltration-based membrane water filter for humanitarian aid. It allows the decentralized supply of clean water in emergency and disaster situations for about 400 persons per unit per day. The filter is designed to function with neither chemicals nor energy nor trained personnel.
A RO unit delivering 20 liters (5.3 U.S. gal) of treated water per day also discharge between 50 and 80 liters (13 and 21 U.S. gal). This led India's National Green Tribunal to propose a ban on RO water purification systems in areas where the total dissolved solids (TDS) measure in water is less than 500 mg/liter.
The chlorination of the water supply helped stop the epidemic and as a precaution, the chlorination was continued until 1911 when a new water supply was instituted. [45] Manual-control chlorinator for the liquefaction of chlorine for water purification, early 20th century. From Chlorination of Water by Joseph Race, 1918.
Water filters produced in Toledo, Ohio in 1895 out of terracotta A large-scale flocculation 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 ...
The process of filtering the water takes 20 seconds, allowing for 0.71 litres (1.5 pints) of water to be filtered. [4] Once a filter has reached its limit, it will not allow contaminated water to be drunk. [4] The LiveSaver bottle has been used by soldiers for drinking water as well as cleaning wounds.

There is a maximum lift into the storm tower of 20 feet. Storm water in excess of these flows were handled by the 2, belt driven Blackstone 14 inch Unchokeable Pumps delivering 250,000 gallons per hour. There are two of these pumps driven by 56 hp Campbell oil (diesel) engines. [1]
