Testing Our Local Water Sources

Since it is highly difficult to transport large amounts of contaminated water for testing, we have used our local river as a testing source. This is a Coli-form bacteria test in which the results were positive for Coli-form bacteria.

Finishing Touches/Moving On To Testing

We are currently putting the finishing touches on the prototype. Notice the addition of wheels to make it possible for an individual to more easily move. Also the addition of LED lighting helps to indicate when the ozone is present. 



We are begging to do many tests on water quality. This is an E-Coli and Salmonella test.

Preliminary Tests of Primary Filter Pods

Today we completed a preliminary test run of one of our filter pods. The filter was filled with alternating layers of plastic mesh, coconut shell activated carbon, and 1 micron porous filter cloth. Keep in mind that the final prototype will use three filter pods to filter the water instead of one. Initial results are promising as nearly all of the visible sediment was removed from our test water. Our next step will be to test for dissolved chemicals, minerals, and bacterial contaminants. We will also do water quality testing that meets national water quality standards.

Moving Forward in February...

A lot has happened since the last update... The team has been working out many problems in the system and we feel confident in out final prototype design.

Things we have discovered:

- We have run tests on the effect of the Oxygen Concentrator on the output of the ozone generator and have determined that it is most cost effective and efficient if we remove the Oxygen Concentrator from the system and instead increase the ozone generators.
- Through preliminary testing of our filters we have found that a (charcoal-->coarse filter cloth---> .1 micron ceramic filter material) setup would be best for our design.

This month we will complete the final prototype chassis in aluminum and finish building out filtration system.

Next month we will add a solar panel system and start testing and making adjustments in order to finalize the prototype and achieve our efficiency goals.
