Septic systems incorporating an ozonation system comprise one or more corona discharge ozone generators receiving air, such as atmospheric air, and having an outlet for the withdrawal of a mixture of air and ozone gas. The system also comprises a septic tank for receiving primary wastewater, and a pump tank receiving secondary wastewater effluent from the septic tank. The ozonation system includes a submersible ozone introduction pump disposed in the bottom of the pump tank, wherein the ozone introduction pump includes an impeller within a housing, the housing having an inlet and a plurality of radial outlet ports along its circumferential area surrounding the impeller. A conduit couples the outlet of the corona discharge ozone generator to the inlet of the impeller housing, wherein the ozone introduction pump reduces pressure in the conduit to draw air into the ozone generator and draws the mixture of air and ozone gas into the impeller housing for introduction into the secondary wastewater. An optional ultraviolet light source may be disposed in the headspace of the pump tank to enhance the activity of the ozone.

All military and many commercial aviators are required to undergo periodic hypoxia training to recognize the onset of hypoxic conditions and practice recovery skills. Current training is performed with the Reduced Oxygen Breathing Device 2 (ROBD2) which mixes oxygen and nitrogen to produce reduced oxygen concentration air mixtures representative of hypoxic conditions. However, the ROBD2 requires bulky compressed gas cylinders which decrease the mobility of the device and increase usage logistics. Additionally, the device delivers a continuous flow, increasing the risk of air starvation. Lynntech has developed an electrochemical oxygen separator to directly reduce the oxygen concentration of the air delivered to the hypoxia trainee. The device accurately removes a variable amount of oxygen from the air stream to produce the required oxygen concentrations, simulating hypoxic conditions from sea level to beyond 30,000 feet. The device will deliver pressure-on-demand flow to a flight mask to avoid air starvation, accurately simulating flight systems. A pulse oximeter, flow meter and oxygen sensor will be integrated into the unit to provide biometric monitoring. The mobile system will weigh less than 40 lbs and operate on 110 VAC. The only consumables will be electrical energy, atmospheric air and liquid water.

Use of high explosives for neutralization of bio-agent stockpiles results in unintentional release of live bio-agents to the surrounding environment most of the time. New biocide containing energetic formulations (such as Al nanoparticles-I2O5) overcome the shortcomings of high explosive approach. Since I2O5 is water or moisture sensitive and loses its biocide properties over time, it needs to be stabilized or passivated. Lynntech, in collaboration with Texas Tech University, proposes an advanced large scale manufacturing and coating process for synthesis and passivation of I2O5. The proposed approach enables the synthesis of I2O5 from the gaseous iodine and oxygen at atmospheric pressure and ambient temperatures without any wet chemistry protocols involved. Preliminary results demonstrated that >99.9% I2O5 powder can easily be produced. Furthermore, synthesized I2O5 can be immediately coated with a passivation coating in order to improve the shelf lifetime and its handling. The power consumption per reactor module was measured to be less than 50 Watts, which makes the proposed approach highly energy efficient for large scale manufacturing. During the Phase I, manufacturing parameters will be further optimized, physical, chemical, and combustion characteristic will be evaluated, and 500 gr to 1 kg sample will be delivered to DTRA for performance testing.
