This project was developed to provide safe, reliable, and convenient direct drinking water services for a large educational campus.
Implemented under a BOT (Build-Operate-Transfer) model, the system serves approximately 28,000 students and faculty members, providing centralized water purification, pipeline distribution, and terminal drinking water access across student dormitories, teaching buildings, and office areas.
The project integrates two sets of nanofiltration central water purification systems with a combined production capacity of 4 tons/hour and a daily drinking water supply capacity of 96 m³/day.
Through centralized purification and dedicated pipeline distribution, the system upgrades traditional decentralized drinking water methods into a modern campus-wide direct drinking water solution.
With approximately 28,000 students and faculty members, the campus faced high daily drinking water demand. The previous decentralized hot water equipment was unable to fully meet concentrated drinking water requirements during peak periods.
The previous instant water heaters mainly provided heating functions without deep water purification capability. Problems such as water scale and insufficient removal of potential contaminants affected drinking water quality.
Campus drinking water needed to meet the requirements of the Drinking Water Quality Standard (CJ94) and provide safe and healthy drinking water for students and faculty members.
The project required a stable centralized drinking water system capable of supplying purified water to dormitories, teaching buildings, and office areas through dedicated pipelines.
28,000
students and faculty members
The project officially started operation in September 2017, providing daily direct drinking water services for approximately 28,000 students and faculty members.
96 m³
/day
Two nanofiltration central purification systems provide a combined production capacity of 4 tons/hour, achieving a daily drinking water supply capacity of 96 m³/day.
7,000
drinking water terminals
The project installed approximately 7,000 drinking water terminals across student dormitories, teaching areas, and office areas, enabling convenient access to direct drinking water.
CJ94-2005
Through pretreatment, nanofiltration membrane purification, and UV sterilization, the system effectively removes suspended solids, heavy metals, bacteria, viruses, and organic pollutants.
The treated water quality meets the requirements of the Drinking Water Quality Standard (CJ94-2005).
The project upgraded the campus drinking water method from decentralized hot water equipment to a centralized purification and pipeline distribution system, providing direct drinking water access with both cold and hot water supply functions.
Our water purification solutions are deployed across a wide range of environments, delivering clean and safe drinking water wherever it is needed most.
The project applied centralized water purification equipment to treat part of the municipal water supply and produce high-quality drinking water for campus users.
The system adopts nanofiltration membrane technology, combined with pretreatment and UV sterilization processes, to remove harmful substances while retaining beneficial minerals and trace elements.
The project established a centralized drinking water purification room and installed two sets of nanofiltration central water purification equipment.
The purification room provides centralized water treatment and supplies purified drinking water through dedicated food-grade pipelines to student dormitories, teaching areas, and office areas.
