3 Outline Project Description Final Deliverables Project Progress Media Selection Media Exhaustion Prototype Development Project Budget Prototype Costs Summary Questions

4 Project Description Problem Arsenic is a global water contaminant difficult to detect hard to remove deadly Available Point of Use (POU) filters for use in a developing country are ineffective at removing Arsenic

5 Project Description Solution C reate a L ine in E xtension for existing POU filters, targeting A rsenic R emoval in H 2 O oute=product/product&product_id=83

6 Scope Research Initial Lab Testing Media Selection Extensive Lab Testing Prototype Development Prototype Testing Prototype Optimization Final Design Report

7 Final Deliverables Working Prototype A line in filter extension for our client s current bucket filter Will remove inorganic arsenic below WHO guideline of 10 ppb Will communicate media exhaustion Final Design Report Client Submittals Prototype Design Report Arsenic Research Report Final Prototype Point One Squeeze Water Filter System.html

12 Media Selection Column Testing Purpose Determine the volume of water that each media can filter Qualitatively determine any aesthetic changes to water (smell, color, etc.) due to media Determine head losses through the media

13 Media Exhaustion Methods Examples Pros Cons Concentration Dependent Quartz crystal microbalance sensor Easy to understand Maximizes media life Lack of Existing Technologies Expensive Volume Dependent Totalizing flow meter Easy to understand Requires pressurized flow Expensive Reliability Time Dependent Timestrip Cost effective Easy to understand Easily replaceable Reliability Minimizes media life significantly

14 Media Exhaustion Chosen Method: Timestrip VERY easy to use and understand 3, 6 and 12 month current time intervals Can be custom made to any time, from 5 minutes to a year Cost effective Very customizable Accurate Proven Success; case studies temperature indicator activation/dp/b007z3rvra

15 Prototype Development Fulfilled Objectives Cheap Lightweight (low shipping costs) Materials PVC tube, nylon fittings Simple Design Easy to install Simple to build Easily reusable Indicates Media Exhaustion Contaminated Water Filtered, Pure Water Removes Arsenic CLEAR H 2 O Prototype Removes Biological Pathogens

16 Prototype Development Unfulfilled Objectives May need to be pressurized Pump Increase elevation difference Additional Considerations May require structural support Shipping costs for replacement media Contaminated Water Filtered, Pure Water Removes Arsenic CLEAR H 2 O Prototype Removes Biological Pathogens

17 Project Budget Calvin Senior Design: $500 Amount Remaining: $0 Client Donations: Prein&Newhof Arsenic Testing Tests Allotted: 250 tests (approx. $4000) Tests Remaining: 135 tests Sawyer Water Products Funding for further testing and equipment on a per need basis

18 Production Costs Prototype Production Costs Media $5.00 PVC $10.00 Hose Barbs $3.00 Timestrip $1.00 Total $19.00
