Hello Everyone!
Having tested the design with our filter at the university, it didn't take long to build the new filter in the village. However it wasn't without it's problems, the frame for the rapid sand filter needed some improvements and we found that the cloth we placed in the filter was limiting the water flow too much to the rapid sand filter because of high consentrating of iron. Small and easy challenges to overcome.
Now the filter is up and running we tested it our selves and got good results. As we are only able to test for arsenic we have sent some samples of the filtered water to the DPHE who will test for other contaminates. This means the villagers can not drink the water from the filter yet but they can certainly cook with it as the boiling of the water will remove potentially harmful contaminates.
Today is our last day in RUET, we fly back to Dhaka to begin the other half of the journey.
For our short talk we are joined by Tonmoy Ahmed, Graduate Civil Engineer from RUET, who has been our local support throughout all our adventures here in Rajshahi. Thank you Tonmoy!!
Enjoy!
