Advanced Technologies For Disinfection at HKIA

24  May  2020

Airport Authority Hong Kong is applying the latest disinfection technologies, including disinfection channel, antimicrobial coating and autonomous cleaning robots, at Hong Kong International Airport to protect passengers and airport staff from COVID-19 infection.

Hong Kong International Airport is the world's first airport where the full-body disinfection channel "CLeanTech" is trialled in live operation. Persons using the facility will have a temperature check before entering an enclosed channel for the 40-second disinfection and sanitizing procedures. The interior surface of the channel is equipped with antimicrobial coating which can remotely kill virus and bacteria on human bodies and clothing by using the technologies of photocatalyst and "nano needles". Sanitizing spray is also applied for instant disinfection. Currently, the facility is designated for use by airport staff who take part in public health and quarantine duties at the airport in relation to arriving passengers.

The Airport Authority is conducting a pilot test of applying antimicrobial coating at all passenger facilities. An invisible coating is applied to handles and seats of Automated People Movers, passenger buses, high-touch surfaces in the terminal, including check-in counters, seating area in the terminal, baggage trolleys, elevators, toilets and more. After completion of the trial, the Airport Authority will consider implementing it as a long term disinfection measure.

Autonomous cleaning robots are also deployed to ensure thorough disinfection of public areas and passenger facilities in Hong Kong International Airport. Intelligent Sterilization Robot, equipped with ultra violet light sterilizer and air sterilizer, is deployed round-the-clock in public toilets and key operating areas in the terminal building. The robot can move around autonomously and sterilize up to 99.99% of bacteria in its vicinity, including both the air and object surfaces, in just 10 minutes.

Steven Yiu, Deputy Director, Service Delivery of the Airport Authority, said, "The safety and wellbeing of airport staff and passengers are always our first priority. Although air traffic has been impacted by the pandemic, the authority spares no effort in ensuring that the airport is a safe environment for all users, and will continue to look into new measures to enhance our cleaning and disinfection work."
