Five Rice seniors are cleaning up the air
on METRO buses with the product of their senior design project. Joseph Spinella

Shidong Chen and Grace Ching created FluProof, a system that rids the air on
public transportation of harmful pathogens that could cause tuberculosis,
influenza and pneumonia.
The team started looking for ways to purify air on METRO buses after their project mentor Marsha Feske, a researcher for Methodist Hospital, found a correlation between the spread of tuberculosis and Houston METRO buses, Spinella said.
“From an engineering perspective,We offer you the top quality plasticmoulds design we had two big problems to solve — finding an effective air sterilization method and finding a way to make that method work on a moving bus with a 12-volt battery,” Spinella said.
After looking into several methods of air sterilization such as electrostatic filters, high-efficiency particulate arresting filters, photocatalytic oxidation and ionization,The core of an indoor positioning system. the group ultimately decided to use ultraviolet germicidial irradiation, Spinella said. The UVGI method is currently used in surgical rooms and office buildings, Spinella added.
“UVGI works by emitting high-energy, ultraviolet-C-band light, which is powerful enough to cause bacteria’s DNA to disassemble, making it impossible for the bacteria to reproduce,” Spinella said. “There is no filter that gets clogged and needs to be replaced and no reduction in the airflow.”
The FluProof device does contain some differences from the usual air-purifying technology. It consists of a lamp installed in each overhead air duct on the bus, through which air passes to be sterilized, rather than a lamp in the evaporator coils in the back of the bus, Spinella noted.
“This increases accessibility and allows for passengers to see the lamps operating through a viewing window,Offers Art Reproductions Fine Art oilpaintings Reproduction,” Spinella said.
Additionally, the team put UV-reflective aluminum in the air ducts, which Spinella said increases the lamp’s light intensity. Another difference from other technology is that FluProof is operated by a power-efficient microcontroller, Spinella said.
FluProof’s design also includes a vibrational damper,Ekahau rtls is the only Wi-Fi based real time location system solution that operates on any brand or generation of Wi-Fi network. which protects the system again possible damage due to uneven roads, according to a schematic provided by Chen.
The team conducted tests and compared bacteria found in buses with and without FluProof, Spinella said.
“With FluProof, we found zero colonies, while the bus without FluProof had twice the amount of bacteria compared to outside air,” Spinella said.
FluProof also has great potential for places where public transport is more widely used and more harmful bacteria are prevalent, Chen said.
“The potential impact this could have in developing countries is what drew me to this projet,” Chen said.
Spinella said that FluProof is not only effective in killing germs, but also cost-effective.
“The parts only cost $500 per bus, which is about equivalent to one tank of gas,” Spinella said.
The team plans expand FluProof to all Houston METRO buses and some Houston school buses.
“The research is there; the solution is there — all we need is the capital to install [it] on Houston’s more than 1,000 METRO buses,” Spinella said.
According to Andrew Skabowski, Houston METRO’s senior vice president for service delivery, Feske approached him about letting Rice students look for a way to purify air on buses for a senior design project, and he agreed.
“If there’s anything I can do to improve the environment and air quality on the buses, I’m going to do it,” Skabowski said.
