Air Purex Ltd have worked on a number of different projects in Biomass gasification for EBRI at Aston University, University of Birmingham and American University of Sharjah UAE.
Low cost filtered drinking water
Country: Pakistan
An investigation into the feasibility of integrating water pumping technologies with activated carbon filtering to supply clean water for drinking and sanitation in Pakistan’s remote communities. The integrated system will operate completely off grid and be powered using the potential energy of flowing water in rivers, streams and creeks. Activated carbon filters will be produced domestically using carbonisation technologies of forest waste.
The Market Need
Pakistan is ranked in the top 10 countries with the greatest number of people living without access to safe water. Most urban and rural water is supplied from groundwater, with over 50% of village households accessing drinking water from hand-pumps. Access to piped water has declined from 41% in 2011/12 to 31% in 2013/14, and is particularly limited in rural mountainous areas.
The health-related impact of this is significant, with hygiene-related illnesses, including diseases caused by unsafe water and poor sanitation, currently costing Pakistan’s economy PKR 112 billion per annum. According to UNICEF, 53,000 children under the age of 5 die in Pakistan every year from diarrhoea due to poor water quality.
