This project is a simple solution that can help people who are in need of good water quality while only using natural ingredients.
Our Coffee-Clay Water Filter can remove dirt particles from the water and make it drinkable. The water we have successfully cleaned so far is from the Mekong River, rain water, municipality water, and underground water.
This is a project that we believe has great potential in addressing the issues of contaminated and dirty water by using a filter which is only made from readily available and low-cost ingredients such as coffee and clay.
Last year, 2019, Laos was hit by one of the worst droughts in a decade. We thought of researching for a solution to save water and an idea we came up with was reusing the water from our household and using it for different purposes. One challenge in achieving this goal was that the water coming out of our household had a bad smell and was discoloured. We found out that water can be treated with natural ingredients such as Alum, Hydrated-lime and Charcoal. These ingredients help make the water colour more clear and remove the unwanted smell. This project will contribute to reducing the wastage of water. This cost-effective project can be our key solution to several water problems.
