With a growing agricultural industry, and no method of disposing of or recycling their used oil, how can a product help Small Island Developing States protect their already stretched water supplies?
Small Island Developing States (SIDS) are recognized by the United Nations as a distinct group of developing countries facing specific social, economic and environmental vulnerabilities
Of North Andros’ 20 billion litres of fresh water resources, only 3% of the oil they use could contaminate it all. This kind of situation is shared by all SIDS.
No safe disposal methods for
medical wastes, motor oils and other
hazardous household wastes
TESTING AND ITERATION
The filtering of oil using only natural rope fibres was researched and investigated. The process uses capillary action (the same phenomenon by which plant draw water up through their roots) which allows only clean oil through, leaving the contaminants behind.
The following is a full break down of the testing.
Below is an overview of the breadth of experiments taken to understand the dynamics of the process
Once cotton was found to have the best potential for filtering maximum flow, experiments were conducted to optimise the flow for the best throughput.
The larger the circle, the higher the flowrate.
To verify the quality of the oil produced during the process, viscosity was tested against new and used motor oil.
The test showed that all samples were re-usable, and that the Cotton rope primed in clean oil was best.
