New Challenges

Powdered Poly Aluminum Chloride

Powdered poly aluminum chloride is being used in Guatemala at one of their hydraulic water treatment plants (El Cambray). This provides a new opportunity for a way to treat water with low alkalinity. Apparently the costs are comparable to alum because you use less of the product, but it costs more per kg. Contact Grasim Industries to determine how to access their product and to see if they are willing to donate some of their product with their charity work.

• Document the activity of AguaClara in wikipedia. Edit the water and sanitation page

Portable water treatment system that can be used in emergencies.

This topic has come up several times and could be a significant contribution. Agua Para el Pueblo has mentioned that they would like to have access to a portable water treatment plant. The challenge is to create a design using lightweight materials that can easily be transported to a location where safe water is needed.

• From CEE 4540 in 2008 we have an emergency water treatment plant proposal.
• From CEE 4540 in 2009 we have 2 proposals

Automated Chlorinator for self serve community water stations

Build on the automated dose controller to create a device that automatically meters in the correct amount of chlorine when a valve is opened to take water from a public standpipe.

Technology Selection Guide

Add a technology selection guide to our website. Provide the basic information on selecting the best water sources and the best treatment processes for those water sources. Describe the data necessary to make an informed engineering decision.
