Week 7 Update - Granular Activated Carbon

• GAC or Granular activated carbon is commonly used to absorb organic and inorganic compounds that may cause undrinkable water due to its foul taste, odor and color [4].
• It would be beneficial to the villagers of Ban Huay Mii and their water supply [1]. The physical and the chemical properties of the activated carbon makes it capable of absorbing unwanted substances such as E.Coli.[5],[1] 
• For the purpose of reducing costs due to frequent replacement of the GAC the water should be in contact with the GAC for at least 5 minutes to ensure proper filtration and usage of the GAC's filtrating lifetime. 
• More information and a visual representation of the filtration method can be found at http://www.simultaneouscompliancetool.org/SCToolSmall/jsp/modules/welcome/documents/TECH6.pdf.
