  3. 4. Amount used of drinking water • 2~3L/1 day, 730~1,095L/1 year • Consider the capacity of container, filter and durability Average water usage / 1 day* Average water usage / 1 year* Average water usage / 1 year (household)* Drinking Water(2-3L) One year Usage of Drinking Water (One Cambodian) = 730 ~ 1,095L One year Usage of Drinking Water (One Cambodian Family - 5 Persons**) = 3,650 ~ 5,475L Remaining(32-33L) • Cleaning • Livestock • Dish washing • Other household activities * Source : Rural Development International Cambodia (RDIC), 2008 ** Source : UNICEF, 2007

  4. Case studies of Appropriate Technologies

  5. 1. Filtration related to Appropriate Technologies (1) Ceramic Water Purifier (CWP) BioSand Filter(BSF) Household-scale ceramic filtration technology is considered among the most promising options for treating drinking water.(UNICEF, WSP-Cambodia) Water and Sanitation Program(WSP) supports purification technology to reduce diarrhea-related diseases. * Source: Use of Ceramic Water Filters in Cambodia, 2007, WSP(water and sanitation program) * Source: Use of BioSand Filters in Cambodia, 2010, WSP(water and sanitation program)

  6. 1. Filtration related to Appropriate Technologies (2) GWP(Gift of Water Purifier) Happy basin 20L/30Minutes two-bucket system • Principle of surface tension and load balance • Nano Ceramic filter polypropylene string-wound filter Tablet

  7. 1. Filtration related to Appropriate Technologies (3) Sari Filtration - Straining Water4Life Filter • price : $4 • durability • portability • ease of use • 1.5-3.0 L/hour • cost for exchange ceramic filter Up to 50 % reduction using eight layers of Sari cloth in Bangladesh (HUQ et al. 2010)

  8. Analysis of products and technologies

  9. 1. Using revised 3P Process • The 3P Process is focused on Product, Patent and Paper. • We revised existing 3P Process as Collaboration with Design Process(3P + CD) Iteration 3 4 Doing Doing Planning & Analysis 5 6 7 Prototype 1 2 Product Concept Doing Product Concept Patent Analysis (IP Process) Paper Analysis Doing(optional) 3 Product Analysis 1st Review Board 2nd Review Board Collaboration Problem Solving Design Analysis (IP Process)

  10. 2. Product - Design basic concept of product (1) Simpler Hollow fiber membrane Minimization of fouling phenomenon Faster Securing of pressure Clean Prefilter Removal of turbidity Durability and semi-permanence Low Cost Ease of cleaning and replacement Reduce Pressure loss problems Sterilization technology Removal of bacteria (except for heavy metal, virus, etc.) Ease of combination with prefilter or polymer hollow fiber membrane
