ABOUT THE CLIENT
DRINKING WATER FACILITY IN CHINA
The city of Yulin in China has been experiencing water supply shortages, particularly in the summer season. Additionally, as the city is hosting provincial sports games in 2023, the demand for improved infrastructure was required. This means that the existing municipal drinking water treatment facilities need to be upgraded, as well as building additional facilities to supply the demand.
WHAT THE CLIENT NEEDED
HIGH QUALITY-DRINKING WATER
To meet the increased demand for water supply, it was necessary to upgrade and build additional water treatment facilities. The Yulin Xisha Municipal Water Facility is included in this infrastructure improvement plan.
To treat the vast amount of safe water needed for the locals, UV technology was included in the process as the final treatment step. As chlorine is used earlier in the treatment path, UV is essential to eliminate waterborne chlorine-resistant pathogens in the water. This is due to chlorine being incapable of inactivating Cryptosporidium, Giardia, or other chlorine-resistant pathogens, which UV has proven to be effective against.
THE SOLUTION
AN UPGRADE FROM CHLORINE TO UV
With the ultimate goal of supplying safe high-quality drinking water to the local residents, UV technology was utilized in the treatment process. UV disinfection is capable of solving the safety challenge of microorganism control, by meeting the strictest defined requirements for bacteria and virus protection, while helping to reduce the use of chemical disinfectants and harmful DBP’s (Disinfection By-Products).
The UV systems installed were 2x MR44-350SS L DN700, to treat a peak flow rate of 70.000m3 per day, with a UVT of 91%.
The installed UV systems will now contribute directly to supplying the local residents with pathogen-free drinking water for many years to come.
