Page: Activated sludge method with membrane technology
membrane technique works with­out addition of chem­icals, energy consumption is relatively low, hand­­­ling is simple and the plants can be easily adapt­ed to different requirements. Membrane filtrat­ion can be used as an alternative to flocculation, sed ...

Page: Bacteria
Bacteria are singlecelled organisms without a nucleus and usually round or rodshaped. They reproduce by cell division (under the best conditions (sufficient food, optimal temp.) very quickly (2040 min.), in waste water purification several h to d). Individual cells ...

Page: Bulking sludge
Bulking sludge is activated sludge with poor floccul­ation and se­dimentation pro­p­er­t­ies (ISV > 150 ml/g). Easily sed­imentable acti­vated sludge has an ISV < 100 ml/g. \\ !UBT444Blähschlamm.jpg ...

Page: History of the activated sludge method
currently most frequently used method of biological waste water purification was discovered in the summer of 1913 by W.T. Lockett in the laboratory of a sewage plant in Manchester. In his experiments he used 2 l glass flasks wrapped in brown paper, filled ...

Page: pH value
Activation methods rebwp8:Activated sludge method are less sensitive to pH variations than trickling bed rebwp8:Trickling bed method methods owing to the greater volumes. The pH in the activation basin should generally be between 6.5 and 8.5 (the growth ...
