-
(Elsevier, 2002)The formation of a stable viscous foam on activated sludge aeration basin surfaces is a world wide problem. Foam is usually comprised of filamentous bacteria occurring predominantly in the mixed liquor. The lack of ...
-
(Elsevier, 1994)Enhanced biological phosphorus removal activated sludge plants often do not remove phosphorus adequately in order to meet legal demands. Currently FeS04 is being added to almost all South African nutrient removal activated ...
-
Antibody recognition of an 18 KDa protein possibly involved in phosphate removal by activated sludge (Elsevier, 2000)Phosphate in wastewater effluent is implicated in eutrophication of water reserves. Enhanced biological phosphate removal by activated sludge is attributed to polyphosphate accumulating bacteria, which release phosphate ...
-
(Water Research Council, 1999-04)Water contaminated with microbiological and chemical constituents can cause a variety of diseases. Water intended for human consumption should be safe, palatable and aesthetically pleasing. Water sources have different ...
-
(Routledge, 2005)Corrosion associated with microorganisms has been recognized for over 50 years and yet the study of microbiologically influenced corrosion (MIC) is relatively new. MIC can occur in diverse environments and is not limited ...
-
(Elsevier, 2001)In this study, different carbon source profiles were generated by inoculating Biolog GN microwell plates, with different dilutions of microbial communities from a number of activated sludge systems. This led to the successful ...
-
(Springer, 2004-12)The biological removal of petroleum products using landfarming has been applied commercially in large scale with relative success. The technology has been widely used due to its simplicity and cost-effectiveness. However, ...
-
(Springer Verlag, 2006)The production of acid mine drainage (AMD) containing high amounts of sulfate, heavy metals and low pH is of increasing concern. AMD is highly corrosive and results in economic and environmental problems. Organic electron ...
-
(Springer, 1998-01)Oxidising and non-oxidising biocides are commonly used in an attempt to control biofouling in industrial water systems. Many of these programmes, however, fail due to the incorrect selection and application of these chemical ...
-
(Elsevier, 1999)The bacterial community structure of phosphate removing activated sludge systems were compared. Samples were obtained from 21 different activated sludge systems, differing in design and phosphorus removal. Community ...
-
(Elsevier, 2003)Biofouling in pipelines is a function of the inner roughness of the specific piping material that is used in distribution systems and the concomitant biofilm formation. To test the effect of velocity on the growth of ...
-
(Blackwell, 2007-06)This paper describes the results of the investigation of a shallow urban lake before, and a second year after, restoration to determine the effects of aeration and bottom-sediment removal on the trophic state and environmental ...
-
(Springer, 2001-05)The importance of sulfate-reducing bacteria (SRB) in nature has been widely recognized for many years. However, little is known about the ecology of SRB. The problem has been detecting, classifying, and quantifying these ...
-
(Water Research Council, 2006-04)Microbial biofilms are problematic in industrial environments where large areas of submerged surfaces are exposed to relatively high nutrient fluxes, providing niches for the formation of copious surface-associated growth. ...
-
(Springer, 2005-09)In this study, we evaluated the heterotrophic microbial communities colonising stone ballasts at diesel depots. The number of bacteria (both total culturable heterotrophic bacteria and hydrocarbon-degrading bacteria) was ...
-
(Elsevier, 2005-01)In this study, we evaluated the hydrocarbon removal efficiency and microbial diversity of different soil layers. The soil layers with high counts of recoverable hydrocarbon degrading bacteria had the highest hydrocarbon ...
-
(Elsevier, 1998)In this study, surface water was used to evaluate the impact of disinfection processes (chlorination, chloramination, ozonation, UV irradiation and hydrogen peroxide) on biofilm formation in potable water distribution ...
-
(Elsevier, 1999-09)Groundwater was treated with chlorine and chloramine to study the incorporation and survival of Escherichia coli in developing biofllms in laboratory-scale units. Membrane filter and standard spread plate procedure were ...
-
(Elsevier, 2002-09)The sensitivity of Lepidium sativum germination to polycyclic aromatic hydrocarbons (PAHs) was investigated in soil(s) artificially and historically contaminated with mixtures of PAH. The level of germination of L. sativum ...
-
(Elsevier, 1995)Immobilization of Acinetobacter cells can provide a method which could possibly be used to explain the mechanism of biological phosphorus removal from AS systems since this may allow the study of pure cultures in their ...
