Shenzhen, a bustling city in Guangdong province, China, boasts a renowned rapid transit system that serves as a lifeline for millions of commuters each day. With an extensive network and a reputation for efficiency, this transit system faces the challenge of providing a comfortable and pleasant journey for its passengers. To overcome issues such as unpleasant odours and limited space within the compartments, a cutting-edge solution was implemented, transforming the transit experience for the city’s residents.
The rapid transit system in Shenzhen encountered obstacles that impacted passenger satisfaction. Unpleasant odours caused by factors such as Total Volatile Organic Compounds (TVOC), yeast, mould, and bacteria posed a challenge to maintaining a fresh and inviting atmosphere within the train compartments. Additionally, the limited space available within the compartments affected the overall comfort of passengers during their journeys, so large obtrusive air purifiers weren’t an option for the rapid transit system.
To address these challenges and elevate the commuting experience, the rapid transit system in Shenzhen sought the expertise of Biozone Scientific and their state-of-the-art solution. By implementing the Air Care solution, the transit system aimed to revolutionize air quality and create a more pleasant environment for passengers.
Everyone benefits from living and working in hygienic, odour-free environments, and that’s where the Air Care comes in. As the name suggests, Air Care treats indoor air, removing all odours, contaminants and airborne particles for a tranquil indoor environment.
Within 24 hours, the integration of the Air Care units into the air conditioning systems produced outstanding results. An analysis revealed a significant reduction of up to 99.9% in airborne bacteria count, airborne fungal count, surface bacteria count, surface fungal count, and TVOC levels. These findings are displayed in the table below and demonstrated the effectiveness and efficiency of our proprietary Photoplasma technology in creating a cleaner and healthier environment for passengers.
| Parameter | Airborne Bacteria Count (cfu/plate) | Airborne Fungal Count (cfu/plate) | Surface Bacteria Count (cfu/cm²) | Surface Fungal Count (cfu/cm²) | TVOC (mg/m²) |
| 0 Hours | 21 | 27 | 20 | 8 | 0.479 |
| 2 Hours | 1 | <1 | <1 | <1 | 0.410 |
| 6 Hours | <1 | <1 | <1 | <1 | 0.398 |
| 24 Hours | <1 | <1 | <1 | <1 | 0.356 |
