Dear All,
Following study has just been accepted and published by the Journal of Cleaner Production:
"Feasibility of ‘Greenhouse System’ for Household Greywater Treatment in Nomadic-Cultured Communities in Peri-Urban Ger Areas of Ulaanbaatar, Mongolia: Way to Reduce Greywater-Borne Hazards and Vulnerability" Uddin et al. (2015) (Link for the accepted manuscript: www.sciencedirect.com/science/article/pii/S095965261501080X)
For this research, greenhouse technology was designed and implemented successfully in the Coldest Capital (Ulaanbaatar, Mongolia) of the world. The study has following novelty statement and the idea can be also fully or partially applied in other parts of the world with similar context.
Highlights:
•Greywater treatment & reuse option has been tested in Nomadic-cultured communities.
•GH-GWTU may have potentiality to significantly reduce greywater-borne hazards.
•Concentration of chemicals in greywater is higher than industrial effluents.
•GH-GWTU may extend the period of treatment in winter cold climate regions.
•Ger settings & nomadic-culture may influence highly on greywater.
Summary:
There are limited studies that focus on greywater treatment and reuse options, particularly in nomadic societies with unique cultural and climatic conditions. Studies relating to household greywater treatment in nomadic-cultured societies are limited. This study aims to address this gap in examining a case with a high concentration of chemical components in the greywater (e.g. where chemical oxygen demand ranged between 35-70032 mg/L). Specifically, an upgraded greenhouse greywater treatment unit (GH-GWTU) was designed and constructed during the summer of 2013 in Ulaanbaatar, Mongolia, in order to assess the technical feasibility, and up-scaling capability, of the system at the community level. Chemical and biological test results indicated that most parameters (e.g. PO43-, NO2-, NH4+) had a high removal rate of up to 98%. Moreover, the greenhouse may extend the treatment period up to 8 months. This study has shown that GH-GWTU is a potential technology that can significantly reduce the chemicals and biological agents in greywater in Mongolian Ger contexts which may reduce the greywater-borne hazards and vulnerability in the area. It can be replicable both at the household and community scale according to resources available for system operation and maintenance.
Thanks a lot
Best regards
