Update: 2/14/2013

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.

Update: 12/29/2012

The team has constructed a preliminary prototype out of plywood. We well continue to add components to this prototype and construct a sheet metal frame into which we will transfer the parts.  

Oxygen Concentration: 

Air is pumped into this compressor and is compressed and sent out to Zeolite towers. 

The compressed air is then pumped through a series of three concentration towers that contain porous aluminosilicate minerals that absorb nitrogen and excess gases and allow oxygen gas to pass through. This process leads to a higher concentration of oxygen gas.

The concentrated mixture of oxygen is then pumped into an ozone generator capable of  producing 100 ppm at 2.5L/min or 300 mg of ozone per hour.

The entire process is regulated by this circuit board. 

Overview: 

The team has reverse engineered an oxygen concentrator and constructed this system in order to increase the  concentration of oxygen that is fed into the corona discharge element for ozone production.

The ozone created will be bubbled throught a tank that will hold the contaminated water. This water will be purified of biological contaminants by the ozone and will be pumped through a series of charcoal based filters to remove any chemical/mineral contaminants. The system will run of lead acid batteries charged by solar; however, the team plans to create a power system capable of running off many sources of power.
