Fall 2011 Contributions - 'Water Treatment Technology Selection Guide' project

Team Members: Li Hui Goh and Siwei Oon

In the course of developing the Decision Support System (DSS) / WTTSG, I was involved in:

1. gathering information on water treatment technologies available with focus on unit treatment processes such as coagulation & flocculation, coagulation & flocculation - sedimentation, chlorination, SRSF, Roughing Filter, etc.  
2. compilation of the available Drinking Water guidelines available such as the US-EPA Drinking Water Standards and the WHO Drinking Water Guidelines
3. piecing together all the information gathered above and coming up with concise write-ups and schematics for the various water treatment technologies featured in the DSS
4. developing the algorithm, using the Multi-Criteria Decision Method, prior to programming it into the guide 
5. developing the guide on Microsoft Excel platform using the Visual Basic for Applications language
6. fine-tuning the DSS to ensure that the DSS generates meaningful results - a suitable, sustainable and implementable combination of technology for the users
7. developing a list of useful questions for users to pose to technology vendors when they are making any purchasing decisions
