In university scientific research and teaching practice, the purity and stability of laboratory water are the 'invisible cornerstone' that determines the accuracy of experimental data. Especially in areas like Yichun, the local water source has relatively high hardness, and the inlet water quality fluctuates significantly during the rainy season, posing a severe test for the adaptability of ultra-pure water equipment. As an important comprehensive undergraduate institution in western Jiangxi, Yichun University has scattered water-use scenarios across multiple disciplines such as chemistry, biology and medicine, with large daily fluctuations in water demand. Traditional water-supply equipment often becomes the 'Achilles' heel' of research work due to unstable water quality and frequent consumable replacement.

Facing the practical difficulties of limited O&M staffing and lack of professional water-treatment experience, Yichun University introduced AiKe's Exceed-Cd series ultra-pure water machine nine years ago. Through nine years of changing seasons, this equipment, with its dual-output scheme of RO pure water and UP ultra-pure water, has comprehensively covered the full-scenario water needs from instrument cleaning to precision analysis. Relying on its three-channel real-time water-quality monitoring, automatic RO membrane flushing and intelligent consumable reminders, the equipment has not only successfully resisted the erosion of local complex water quality on the RO membrane, but also maintained the UP ultra-pure water resistivity stably at the benchmark level of 18.25 MΩ·cm over the long term, proving with solid operational data the hard-core strength of domestic high-end water-treatment equipment, and building a nine-year-long water-defense line for the university's scientific research experiments.

I. AiKe Exceed-Cd Series Safeguards Yichun University's Nine-Year Stable Operation
As an important comprehensive undergraduate institution in western Jiangxi, Yichun University has scattered water-use scenarios across multiple disciplines such as chemistry, biology, medicine and materials. During daily experiments, water demand fluctuates greatly at different time periods, and traditional water-supply equipment often suffers from unstable water quality and frequent consumable replacement.

The local water source in Yichun has relatively high hardness, and the inlet water quality fluctuates markedly during the rainy season. Ordinary ultra-pure water equipment is prone to RO membrane scaling and a sharp drop in purification-column lifespan, making it difficult to continuously and stably produce RO pure water and UP ultra-pure water that meet experimental requirements. At the same time, university laboratories have limited O&M staffing and lack professional water-treatment maintenance experience; traditional equipment has cumbersome operation and unclear fault warnings, easily leading to the hidden danger of substandard water quality going undetected.
Since the AiKe Exceed-Cd series ultra-pure water machine entered Yichun University nine years ago, relying on its three-channel real-time water-quality monitoring, automatic timed RO membrane flushing and intelligent consumable-expiry reminders, it has perfectly adapted to local water conditions. The UP ultra-pure water resistivity has been stably maintained at 18.25 MΩ·cm over the long term, and the dual-output water supply covers the full-scenario water needs of instrument cleaning and precision analysis, greatly reducing the O&M burden and building a reliable water-defense line for the university's scientific research experiments.

II. AiKe Exceed-Cd Ultra-Pure Water Machine Serves Yichun University with Free On-Site Maintenance Protecting Research Water

Recently, AiKe's after-sales engineers went to Yichun University in Jiangxi Province to provide free on-site maintenance services for the Exceed-Cd series ultra-pure water machine that has been in use for 9 years, using professional after-sales support to ensure the stable supply of research water in the university's laboratory.

The AiKe Exceed-Cd series ultra-pure water machine selected by Yichun University's laboratory can produce dual water qualities of RO pure water and UP ultra-pure water, fully meeting various experimental water standards such as teaching experiments and physical/chemical analysis. After 9 years of daily high-frequency use, the equipment still runs smoothly with stable and reliable output water quality, fully reflecting the solid product quality of AiKe's ultra-pure water equipment, and providing solid water support for the university's scientific research and teaching work.

During this on-site maintenance, the engineers conducted a comprehensive inspection of the equipment's water pipelines, filtration consumables, control system and water-quality monitoring module, cleaned the internal scale of the equipment, investigated aging hidden dangers, calibrated water-quality detection parameters, and eliminated potential problems brought by long-term operation.

While providing high-performance laboratory ultra-pure water equipment, AiKe insists on improving its after-sales support services, offering professional on-site maintenance support for universities and research institutions to extend equipment service life. With its excellent product strength and considerate after-sales service, AiKe has won the trust and praise of many university users.
