This Technology Transfer Advances Bangladesh's
- Nationally Determined Contribution to develop climate resilient housing, and its recognition of water security as a key area for which to address the adverse impacts of climate change.
The Climate Technology Centre is seeking proposals for the technologies for saline water purification at household level and low-cost durable housing for coastal areas of Bangladesh.
Lack of basic sanitation and safe water is a major issue for women and girls who live in poor and overcrowded areas. This joint undertaking by the Water Supply and Sanitation Collaborative Council (WSSCC) and the Water, Engineering and Development Centre (WEDC) collects and analyses noteworthy examples that illustrate the impact of women on water, sanitation, and hygiene (WASH) activities, in order to show its potential for transformative change.
Unique particles derived from acrylonitrile or other materials which are capable of selectively absorbing uranyl from groundwater surface water and wastewater.Applications:This technology can be used to improve the quality of a water supply by safely effectively and inexpensively removing uranyl ions from the water. The presence of uranium in groundwater is a growing problem in the United States and one without effective treatment to date. These particles can also be used in portable field systems for analysis of uranyl content on site.
Chemical contaminants such as nitrogenous wastes found in aquacultures or groundwater may contaminate nearby areas and drinking water supplies. Groundwater pollution may be caused by activities such as industrial waste disposal accidental spills fuel tank leakage or application of fertilizers herbicides or pesticides to crops. Natural causes such as arsenic also may result in groundwater contamination. Organisms are a major cause of water and aqueous environment contamination and are one of the world’s largest health concerns.
The on-line monitoring capability of heavy metal ions would be of interest to the laboratory water market. Heavy metal ions are a cause of environmental pollution from a number of sources including lead in petrol industrial effluents and leaching of metal ions from the soil into lakes and rivers by acid rain. The concept of stripping voltammetry is a well understood and highly respected technique that has been applied for trace level detection of heavy metal ions such as zinc lead cadmium copper mercury arsenic etc.
