Antibiotic resistant bacteria found in fertilizer
Vancomycin resistant enterococci (VRE) have been found in sewage sludge, a by-product of waste-water treatment frequently used as a fertilizer. view more (2009-05-29)
More biogas, less sludge
Germany has more than 10,000 sewage plants, using costly processes to treat household, industrial and restaurant waste water. The treated water is discharged back into river and lake systems. What remains is an organic / inorganic mixture of sludge. The issue is how to dispose of this residue. Up to now, sewage sludge has been used as an... view more... (2002-11-14)
Sewage Sludge Digestion: Less sewage residues, more energy
On behalf of the Abwasserzweckverband Heidelberg (Association for Sewage), the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB) in April of last year added a high-rate stage to the Heidelberg municipal sewage plant. The aim was to increase the economy of the digestion without putting the disposal line out of operation. The... view more... (2002-08-30)
Energy efficient sewage plants
High-rate digestion with microfiltration is state-of-the-art in large sewage plants. It effectively removes accumulated sludge and produces biogas to generate energy. A study now reveals that even small plants can benefit from this process. view more (2009-08-14)
Behavior modification could ease concerns about nanoparticles
In an advance that could help ease health and environmental concerns about the emerging nanotechnology industry, scientists are reporting development of technology for changing the behavior of nanoparticles in municipal sewage treatment plants - their main gateway into the environment. view more (2009-11-12)
Cholesterol-busting bug with a taste for waste
A novel species of bacteria with cholesterol-busting properties has been discovered by scientists at the Universidad Complutense de Madrid, Spain. Dr Oliver Drzyzga and colleagues isolated the new bug, called Gordonia cholesterolivorans, from sewage sludge. view more (2009-05-15)
Adding high doses of sludge to neutralise soil acidity not advisable
A University of the Basque Country PhD thesis has analysed the application of waste sludge from EDAR (Estación Depuradora de Aguas Residuales - Waste Water Purification Plant) to acid soils which have limited capacity for neutralising the acidity. view more (2009-01-09)
Space technology disposes of sludge
Research funded by the European Space Agency into ways of feeding future astronauts on missions to Mars is about to find a very down-to-earth application - how to dispose of the sewage sludge left over after wastewater treatment. The MELISSA (Micro-Ecological Life Support Alternative) project, which ESA is funding in companies and research... view more... (2002-05-15)
Drinking water in Gaza Strip contaminated with high levels of nitrate
Palestinian and German scientists have recommended to the authorities in the Gaza Strip that they take immediate measures to combat excessive nitrate levels in the drinking water. view more (2008-08-15)
Too much technology may be killing beneficial bacteria
Too much of a good thing could be harmful to the environment. For years, scientists have known about silver's ability to kill harmful bacteria and, recently, have used this knowledge to create consumer products containing silver nanoparticles. view more (2008-04-30)
New use for human hair
Agricultural crop production relies on composted waste materials and byproducts, such as animal manure, municipal solid waste composts, and sewage sludge, as a necessary nutrient source. view more (2008-12-29)
Less trouble at mill, thanks to earthworms
Waste from the textiles industry could with the assistance of earthworms and some animal manure become a rich compost for agriculture, according to a report in the International Journal of Environment and Pollution. view more (2009-07-16)
Turning muck into brass: engineer in line for £50,000
Sewage treatment may not be the world's most glamorous job, but someone has to do it. Now Southern Water engineer David de Hoxar could rake in £50,000 after being shortlisted for the UK's biggest engineering prize - the Royal Academy of Engineering MacRobert Award - for inventing a new settlement tank to separate muck from water. The de... view more... (2001-07-03)
DMSO raises a stink at sewage treatment plants
Researchers believe they've found the source of a stinking problem that has plagued areas surrounding sewage treatment plants for decades. view more (2005-12-21)
Scientists plan to reclaim contaminated land by using domestic waste
A novel technique to combat the UK's looming landfill crisis begins its first field trials in Yorkshire this week. The technique known as Biostore combines stabilised sewage sludge with industrial waste such as coal shale and demolition waste to create solid building foundations. It has been developed by scientists at Imperial College London, and... view more... (2004-04-27)
UWE develops detectors for oestrogen in river water
Small quantities of oestrogens, which are female hormones, are excreted from the body and thus enter the sewage system. Although these chemicals seem to be largely removed in sewage treatment, it seems that minute quantities remain and thus can enter rivers to which treated sewage is discharged. These very low levels of oestrogens have been... view more... (2001-08-14)
The bitter side of sweeteners
Sewage treatment plants fail to remove artificial sweeteners completely from waste water. view more (2009-06-18)
New environmental research lab helps get more out of waste
A new London research laboratory developing fresh solutions to the perpetual problems of how best to get rid of our waste has reopened its doors today after a UKP1.5 million facelift. Researchers based in the new Roger Perry Environmental Engineering laboratory at Imperial College are behind a number of innovative new waste reclaim and reuse... view more... (2002-03-27)
