Parks, airports, subway stations, high-speed railway stations and other public places, due to the characteristics of large crowds gathering and dispersing, water purifier water production and extreme heating function have a severe test. On the basis of ensuring the filtering effect of safety and health, the design and installation of the equipment take into account the safety risks in the public environment, and the convenience and comfort of users of different ages and heights, and even the subsequent cleaning and maintenance should be carefully considered.

The public places represented by stations and airports serve the floating population of different genders, ages, occupations, nationalities or nationalities, and different health conditions. They are the most direct “Windows” to show the image of a city. As a supporting facility for urban public services, its drinking water facilities not only need to avoid health and safety hazards brought by the floating population, but also need to use high-quality services to reflect the appearance of the city, and the requirements for various indicators of products and services are very strict.

During the Expo, Litree will provide the exclusive public direct drinking water service for the Shanghai Expo Site, with a total of 117 direct drinking water points. This is the first time in the history of the Expo that the organizer will provide free direct drinking water. Direct drinking water has passed more than 20,000 water quality tests in half a year, serving 73 million tourists and supplying 1,000 tons of direct drinking water every day, without a single drinking water safety accident. All the water quality indicators have reached the national Sanitary Standards for Direct Drinking Water and Water Quality Standards for Drinking water, and the main indicators are better than the European Union standards.

Garden Expo direct drinking water uses the core technology of World Expo, using the combination process of "activated carbon +pvc ultrafiltration membrane + UV". Activated carbon can effectively remove small molecules of organic matter in water, reduce chroma and odor; PVC ultrafiltration membrane can completely remove suspended particles, bacteria, viruses, colloids and macromolecular organic matter in water, especially effective on the removal rate of bacteria; Uv has a strong bactericidal effect, can play a double protective role. The application of this technology in the World Expo shows that the water quality indexes of direct drinking water not only meet the requirements of the current national Sanitation Standards for Drinking Water (GB5749-2006) and the Water Quality Standards for Drinking Water (CJ94-2005), but also the main health indexes are even better than the European Union standards. Continuously and stably provide quality direct drinking water service for the park with an average daily flow of 8.3W people.
