Thames River, England

Satriana (2) provides a summary of the development of flue gas treatment technology. The first commercial application of flue gas scrubbing for sulfur dioxide control was at the Battersea-A Power Station [228 MW(e)] in London, England, in 1933. The process used a packed spray tower with a tail-end alkaline wash to remove 90 percent of the sulfur dioxide and particulates. Alkaline water from the Thames River provided most of the alkali for absorption. The scrubber effluent was discharged back into the Thames River after oxidation and settling. A similar process was also operated at the Battersea-B Power Station [245 MW(e)] beginning in 1949. The Battersea-B system operated successfully until 1969, when desulfurization efforts were suspended due to adverse effects on Thames River water quality. The Battersea-A system continued until 1975, when the station was closed. 

ISSOto 1750 AD Little Ice Age . The River Thames in England regularly freezes with ice so thick that fires could be lit on it to roast animals at fairs. 

The earliest commercial r licadons of the limestone/liine process were in London, England. The first unit at the Battersea Power Station was put into operation in 1931. This was followed by inqiroved units at Bankside, Swansea, and Fulham. The initial process was primarily a once-through watra- wash, using a small amount of chalk sluny added to the natural alkalinity of the Thames River. In 1938, the Fulham Power Plant was the first to use recycle in the process. This process is basically the same as the mod n limestone/lime systrans. 

When 200 L of cyanide were spilled into the River Wey in Surrey, England in May 1999, peroxide was added to the river to save the fish. The peroxide breaks down into water and oxygen and raises the pH of the polluted water, causing the cyanide to break down more rapidly. The fish were saved by the additional oxygen added. The Environment Agency s Thames Region now includes peroxide crystals, or sodium carbonate peroxyhydrate, in their response kits for cyanide spills (OSHS, 1999). 

Alluvial Clay. A brickmaking clay of river valleys typified in England by the clays of the Humber estuary, the Thames valley, and the Bridgwater district. The composition is variable. 

Very limited data exists on the presence and fate of dmgs of abuse in the United Kingdom environment Monitoring of ilhcit dmgs in the United Kingdom has been undertaken in only one river in England (the River Thames) and two rivers in Wales (the River Taff and Ely).
