Refining water void of heavy metals
Some water sources in Uganda especially River Nyamwamaba, in Kasese, is affected with heavy metals. This technology sets out to forestall such a challenge by ensuring that water is purfied through this biosebent technology.
This technology uses locally available biological materials especially agricultural waste to remove heavy metals from water and waste water. This effort alone contributes towards the acheivement of sustainable development goals 6, 11 and 13. Besides the technology provides an economical alternative for removing toxic heavy metals from industrial waste water thus aiding in enviromental remediation. The project is being implemented in Kasese, district in Nyamwamba valley and, to make the project as low cost as possible, coffee husks and cotton seed cakes are used as bisorbents.
The removal of heavy metals is done through a physiochemical process that occurs naturally in the biomass which allows it to passively concentrate and bind its contaminants onto its cellular structure. The entire process is called bisorption and the biomass used in this application is called a biosorbent.
Market deployment considerations
No market barrier since there are few players
