-
(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 ...
-
(Water Research Council, 1993-07)Bacterial communities in water-cooling systems treated with bactericides often become resistant to these bactericides. This has been ascribed to selection for resistant cells. Certain bacteria, having a high inherent ...
-
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, 1993-10)Biofouling in industrial water systems is normally prevented by the use of bactericides. However, bactericide programmes often fail owing to the lack of suitable techniques for determining the in situ bactericide concentration ...
-
(Academic Journals, 2005-05)Molecular marker analysis is becoming increasingly capable of identifying informative genetic variation. Amplified fragment length polymorphism markers (AFLPs) are among the recent innovations in genetic marker technologies, ...
-
(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 ...
-
(Water Research Council, 1989-01)Bacteria forming biofilms occur in all open water cooling systems where they accelerate metallic corrosion, reduce flow rate and decrease heat energy transfer rate. A population structure study of seven systems was conducted. ...
-
(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 ...
-
(Water Research Council, 2002-07)Diversity and dynamics of microbial communities have been analysed by culture-dependant methods, which exclude the majority of fastidious microbes due to the selective nature of the media. Molecular methods have been used ...
-
(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 ...
-
(Water Research Council, 1999-07)In this study, a water cooling tower was used as a low-rate biofilm reactor for treating municipal wastewater. The performance of the system was evaluated at three different flow rates. The biofilm reactor gave the best ...
-
(Water Research Council, 1999-01)The diversity and dynamics of microbial communities of phosphorus-removing and non-phosphorus-removing activated sludge systems have mostly been analysed by culture-dependent methods. A more direct method is the isolation ...
-
(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 ...
-
(Water Research Council, 1992-04)Bactericides were applied to experimental open recirculating cooling-water systems at concentrations found to be effective under laboratory pure-culture conditions. Total aerobic plate counts and bacterial population ...
