THE WORLD'S first full-scale experiment to clean up municipal sewage with a reactor full of algae has recently started near Nottingham in the UK (New Scientist, Vol 140, No 1893). The reactor or "biocoil" system developed by Stephen Skill at the London-based Biotechna, contains chlorella algae packed into a 5-m-high …
Kanpur -- the second most polluted city on the Ganga after Calcutta -- has come under the microscope during the first phase of the Ganga Action Plan (GAP). However, the city's residents will have to wait for another two years before the river water quality improves because the effluent treatment …
ENVIRONMENT protection need not be a dirty word in business. In fact, instead of being considered a financial loss, it can be turned into a profit making proposition. Industries are beginning to realise that "waste minimisation" can not only help them save money by saving raw material and fuel, but …
The increasing pressure on the West Bengal government to clean up industrial pollution in the state has forced it to seek Japanese aid. Japanese experts will help the state government set up effluent treatment plants and upgrade the capabilities of the state pollution control board in line with growing needs. …
SORTING out similar types of plastics from waste may now be possible through a system based on the different ways various plastics reflect a near-infrared light (Environmental Science and Technology, Vol 27, No 7). The different reflection patterns are then analysed by an artificial nerve-like computer programme, which is "trained …

The figure shows the elements of a small-scale wastewater treatment system in use at Stensund high school in Sweden. First, a sedimentation tank stores the wastewater produced over two days (1). The water then is led to a soil filtration tank (2) with sulphuric bacteria under anaerobic (non-oxygen) conditions, which …
TRADITIONAL communities developed ingenious ways of making use of wastewater. And, experts involved in the modern science of ecological engineering can learn a great deal from them. There is a growing realisation that the term "wastewater" is a sign of human inability to recognise a valuable resource. Traditional societies throughout …
