Central South University Q-Center500-RO Pure Water Treatment Equipment

Implementation Plan

• Central preparation system: equipped with Q-Center500-RO pure water treatment equipment, using municipal tap water as the inlet, adopting a two-stage reverse osmosis process, producing 500 liters/hour of high-quality pure water with a conductivity of ≤ 5 μ s/cm, and transported to various experimental areas through a circular pipeline.
• Partition circulation design: Based on the laboratory layout of different buildings at Central South University, partition circulation pipelines are set up, equipped with constant pressure water supply systems and UV sterilization devices, to ensure that the water quality in each area's pipeline network is always fresh and stable. Each partition is equipped with an independent circulating pump group, which can intelligently adjust its operation according to water consumption.
• On demand water intake terminal: Install intelligent water intake terminals in each laboratory, supporting functions such as quantitative water intake, real-time water quality display, and card swiping records. Set differentiated water intake permissions and water quality standards for basic teaching laboratories and research laboratories based on their different needs.
• Intelligent management system: equipped with an IoT remote monitoring platform, real-time monitoring of the central system and the operation status of each partition, supporting functions such as mobile phone alarm, water usage statistics, and consumable life prediction.

Implementation results

• Improvement in water quality and experimental results: After the system was put into operation, the water quality at each water intake point stabilized to a conductivity of ≤ 5 μ s/cm, and the microbial indicators were comprehensively better than the GB6682-2008 standard, completely eliminating problems such as abnormal experimental phenomena and data deviations caused by water quality issues. The experimental success rate and standardization of basic chemistry, biology, materials and other experimental courses have significantly improved, and the data consistency of student experimental reports has been significantly improved. The improvement of water stability in scientific research laboratories provides reliable guarantees for research work such as material preparation and sample analysis, and supports the smooth implementation of multiple national level scientific research projects.
• The management efficiency and economic benefits are highlighted: the centralized supply meets the concurrent water demand of multiple laboratories during peak hours, and the water pressure and quality remain stable during the concentrated period of experimental classes, with a water use efficiency improvement of over 60%.
• Unified management of equipment has reduced the human damage rate by over 90% and significantly lowered the equipment failure rate.
• Unified and professional predictive maintenance maximizes the utilization of consumables, reducing overall operation and maintenance costs by about 35% compared to decentralized models.
• Intelligent management reduces 90% of manual maintenance and recording work, freeing laboratory managers from tedious equipment maintenance and allowing them to focus more on experimental teaching and research itself.
