In Linyi, Shandong Province, the production workshop of Shandong Qingqingquan Environmental Technology Co., Ltd. is a hive of activity, with custom water treatment equipment being assembled in an orderly fashion. The company’s order book is full, and it continues to receive a steady stream of inquiries from both domestic and international clients. With years of deep experience in the water treatment industry, Qingqingquan focuses not only on the R&D and manufacturing of hardware—such as reverse osmosis (RO) systems, water softening equipment, and commercial water purification units—but also on the development of its own proprietary digital and intelligent operations and maintenance platform. This platform enables water purification units—deployed across China and exported abroad—to continuously transmit operational data. By leveraging AI algorithms for intelligent analysis, the company has transformed its approach from reactive after-sales support to proactive, precise service.
