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)
Water recycling in the textile finishing industry
The treatment and recycling of colored wastewater from dyestuffs producing and textile finishing industries have always been a non-trivial problem for the sewage engineering sector. The recycling of process water of textile mills is often hindered by remaining colour of azo-dyes after conventional wastewater treatment. Because of rising costs of... view more... (2002-11-22)
Hypertension and cholesterol medications present in water released into the St. Lawrence River
A study conducted by Université de Montréal researchers on downstream and upstream water from the Montreal wastewater treatment plant has revealed the presence of chemotherapy products and certain hypertension and cholesterol medications. view more (2009-01-27)
The largest leachate plant in Europe
Leachates are the dirty or contaminated waters from landfills, produced as a consequence of both the moisture already present in the waste as well as of rainwater contaminated on passing through the waste material. The leachate plant has a capacity for treating 350,000 cubic metres a year, equivalent to the amount of wastewater generated by a city... view more... (2004-02-25)
U of Minnesota researchers discover high levels of estrogens in some industrial wastewater
In a groundbreaking study, civil engineering researchers in the University of Minnesota's Institute of Technology have discovered that certain industries may be a significant source of plant-based estrogens, called phytoestrogens, in surface water. view more (2009-08-11)
A green future for scrap iron
Take a close look at that cheap piece of scrap iron before you toss it in the trash. view more (2008-11-04)
Mopping up mercury - a new solution to an old problem
A pilot plant employing a new type of bioreactor has successfully been used to treat mercury-contaminated wastewater in Germany. Dr Irene Wagner-Döbler and colleagues from the GBF National Research Centre for Biotechnology, Germany, developed the technical scale plant based on previous work on mercury-resistant bacteria. Biofilms of bacteria... view more... (2001-04-01)
New system of wastewater treatment could reduce the size of treatment plants by half
A group of researchers from the University of Granada (Universidad de Granada) have come up with a wastewater treatment system which has three clear advantages with respect to systems currently used: it is possible to obtain cheaper water of a higher quality, it considerably reduces the size of treatment plants (by more than half) and it minimizes... view more...

Gaiker co-ordinates a world-wide project for the reuse of purified wastewater
Gaiker is co-ordinating a world project for the reuse of purified wastewater and the aim of which is to study the possibility of using this as an alternative water resource. Just in the European Union, the implementation of strategies for the reuse of purified wastewater would enable the availability of water to be increased by 6%, which would... view more...

Tiny Super-Plant Can Clean Up Hog Farms and Be Used For Ethanol Production
Researchers at North Carolina State University have found that a tiny aquatic plant can be used to clean up animal waste at industrial hog farms and potentially be part of the answer for the global energy crisis. view more (2009-04-08)
Using plants and microbes to purify polluted industrial wastewater
Wetlands are nature's water filters. They collect water around river mouths and marshes, and whole communities of plants and micro-organisms feed off detritus in these murky depths. Conventional chemical treatments of industrial waters consume cash, energy and time. Wetlands, by contrast, grow and clean themselves while they act as... view more... (2003-10-07)
Antibiotics, antimicrobials and antifungals in waterways
Antibiotics, antimicrobials and antifungals are seeping into the waterways of North America, Europe and East Asia, according to an investigation published in the peer-reviewed journal Environmental Health Perspectives (EHP). view more (2009-06-10)
DTI Awards for Environmental Biotechnology
Projects to share nearly £400k New environmentally friendly ways of treating wastewater from the textile industry are among projects to share nearly £400k in funding, announced today by the Science and Innovation Minister, Lord Sainsbury. The projects are part of the DTI's BIO-WISE programme, which encourages companies to use... view more... (2001-07-06)
Phthalic symbol
Immobilized microbes can break down potentially harmful phthalates, according to researchers in China, writing in the International Journal of Environment and Pollution. view more (2009-06-22)
These shells don't clam up: Innovative technique to record human impact on coastal waters
With their sedentary lifestyles and filter-feeding habits, clams have been silent witnesses to the changes that humans have inflicted upon their waters. view more (2008-12-03)
New method monitors critical bacteria in wastewater treatment
Researchers have developed a new technique using sensors to constantly monitor the health of bacteria critical to wastewater treatment facilities and have verified a theory that copper is vital to the proper functioning of a key enzyme in the bacteria. view more (2009-02-05)
Remote expertise for wastewater treatment
Getting expertise where it is needed in wastewater treatment is the goal of TELEMAC, which has developed remote, and local monitoring and control solutions so industries can obtain all the benefits of anaerobic waste treatment while minimising costs and complications. view more (2004-09-27)
Brush anode and tubular cathode scale up microbial fuel cells
Generating electricity from renewable sources will soon become as easy as putting a brush and a tube in a tub of wastewater. view more (2007-03-22)
Wastewater produces electricity and desalinates water
A process that cleans wastewater and generates electricity can also remove 90 percent of salt from brackish water or seawater, according to an international team of researchers from China and the U.S. view more (2009-08-07)
Better sludge through metagenomics
Few stop to consider the consequences of their daily ablutions, the washing of clothes, the watering of lawns, and the flush of a toilet. However, wastewater treatment-one of the cornerstones of modern civilization-is the largest microbially-mediated biotechnology process on the planet. view more (2006-09-26)
