Yet they are less effective in lowering BOD, which is, sometimes necessary to reduce odors and meet municipal discharge requirements. Dissolved air flotation (DAF) systems are widely used to separate 95-99 percent of fats, oils and greases (FOG) and total suspended solids (TSS) in organic wastewater treatment plants. The SOLVOX system was designed and retrofitted for an existing 225,000 gallon aerobic equalization (EQ) tank feeding a dissolved air flotation (DAF) unit. Murray Hill, NJ.В andВ New Providence, NJВ /PRNewswire/ - A custom oxygen booster system from Linde LLC, known as the SOLVOXВ® oxygenation system, proved effective in dramatically lowering biochemical oxygen demand (BOD) for an on-site wastewater treatment facility for Koch Foods LLC poultry deboning plant inВ Morristown, Tennessee.

In 1917 Linde Air Products joined with four other companies that produced acetylene, among other products, to form Union Carbide and Carbon Corporation. One company formed to use LindeвЂ™s later patents was the Linde Air Products Company, founded in Cleveland in 1907. In the early days of oxygen production, the biggest use by far for the gas was the oxyacetylene torch, invented in France in 1904, which revolutionized metal cutting and welding in the construction of ships, skyscrapers, and other iron and steel structures. He then obtained oxygen and nitrogen from the liquid air by slow warming. The company he established to promote this invention was an international success: refrigeration rapidly displaced ice in food handling and was introduced into many industrial processes.Д®dgar Fahs Smith Collection, Kislak Center for Special Collections, Rare Books and Manuscripts, University of Pennsylvania Commoditized AirДЄfter a decade Linde withdrew from managerial activities to refocus on research, and in 1895 he succeeded in liquefying air by first compressing it and then letting it expand rapidly, thereby cooling it. His research there on heat theory, from 1873 to 1877, led to his invention of the first reliable and efficient compressed-ammonia refrigerator. After working for locomotive manufacturers in Berlin and Munich, he became a faculty member at the Polytechnic in Munich. Linde, the son of a Lutheran minister, was educated in science and engineering at the Federal Polytechnic in Zurich, Switzerland. Oxygen became a common commodity that was supplied to hospitals and industries and was later used in rocket fuel, but this was not the German engineer's first important contribution. It was the achievement of Carl von Linde (1842вЂ“1934) in 1902 to take oxygen from the air itself, and he was soon extracting it in quantities approaching 1,000 cubic feet per hour.

Initially, however, the discovery had little impact outside the laboratory since oxygen could be produced only in the lab and in limited quantities by chemical or electrolytic means. The discovery of oxygen and investigation of its role in chemical reactions was of crucial importance in changing the science of chemistry (see Joseph Priestley and Antoine-Laurent Lavoisier).
