Guangzhou Metro Group was established in 1992 as a wholly state-owned enterprise of the Guangzhou municipal government. Its activities extend from new-line planning and construction to investment and financing, and from metro services to intercity rail and trams, with projects in the Greater Bay Area, other Chinese cities and overseas markets.
The original profile reported 676.5 kilometers of routes under the group's operating responsibilities, including Guangzhou's local metro and tram systems, the Guangqing and Guangzhou East Ring intercity railways, Nanchang Metro Line 3, Sanya's tram service and Lahore's Orange Line. It also described 292 kilometers of metro construction and involvement in 33 railway, intercity, transport-hub and municipal-road projects at that time.
BIOSUN provides air treatment solutions for rail transit. Its Chinese project profile reports experience across more than 100 rail projects in China and overseas, with applications addressing airborne microorganisms, particles, chemical gases and emissions from interior materials in occupied transport environments.
Applications cover train interiors, platforms, station halls and public restrooms. BIOSUN applies PHOTOPLASMA technology to selected microbial, gaseous and particulate air treatment requirements. Performance should be assessed against the equipment specifications, relevant test reports and operating conditions.
