Biomimicry: beetle-based water harvesting
06 Jun 08
A pioneering water harvesting system inspired by the Namib Desert Beetle is one the biomimicry innovations that will feature in the first annual edition of Nature's 100 Best© book. Material engineers have created synthetic versions of the beetle’s fog-catching technology to enable buildings and tents to harvest water vapour.
Water treatment: potential of new technologies for developing countries
25 Apr 08
Nature publishes a review of some of the science and technology being developed to improve the disinfection and decontamination of water, as well as efforts to increase water supplies through the safe re-use of wastewater (e.g. with membrane bioreactors) and efficient desalination of sea and brackish water.
Rural water supply: the risks of a technology-based indicator
25 Apr 08
Low cost behavioural and technology changes need to be explored and perhaps offered as options alongside those more expensive alternatives in rural water supply in order to increase cost-effectiveness and progress.
Arsenic removal: field testing the Kanchan Arsenic Filter in Cambodia
22 Mar 08
Developed by Massachusetts Institute of Technology (MIT), the Kanchan Arsenic Filter is a low-cost household-level technology using simple materials such as gravel and iron nails. After a successful laboratory study, the filter is now being field tested in Cambodia.
Ecosan: zero-waste toilets developed by IIT Kanpur, India
27 Feb 08
Soon it will be possible to have flush toilets with minimal wastage of water. Led by Prof. Vinod Tare, researchers from the environmental engineering department of the Indian Institute of Technology (IIT) Kanpur have developed a toilet that will reuse the water that goes into flushing rather than discharging it along with the excreta.
Point-of-use treatment: Vestergaard Frandsen launches LifeStraw(R) Family
27 Feb 08
Vestergaard Frandsen has launched LifeStraw(R) Family, a new point-of-use water treatment device targeted for use in developing countries, that can provide a typical family with drinking water for 1.5 years. It builds on the success of the award-winning LifeStraw(R) Personal.
Pit latrines: practical construction manual
26 Feb 08
Dutch NGO, Foundation Connect International, has published a simple and practical manual for the construction of pit latrines with a focus on slab production.
Household treatment: study evaluates performance of ceramic filters
26 Feb 08
The ceramic silver-impregnated pot filter (CSF) is a low-cost drinking water treatment system currently produced in many factories worldwide. CSFs from three production locations - Cambodia, Ghana and Nicaragua – were tested for effective pore size, removal efficiency of microorganisms, and water production.
