In various cities of Weifang, Shandong Province, a "water-saving diagnosis public welfare service" activity targeting key enterprises is sparking a green transformation trend. A professional team composed of the Water Resources Bureau of Zhucheng City and Beijing Xinhua Water Conservation Certification Co., Ltd. has gone deep into enterprises such as Shandong Daye Co., Ltd., and provided scientific basis for energy-saving renovation of water supply equipment through a "look, hear, and ask" diagnostic approach.
During the diagnostic process, the team utilizes advanced equipment such as IoT sensors and ultrasonic flow meters to monitor key indicators such as pump operating efficiency, pipe network leakage rate, and water usage data fluctuations in real-time. For example, in a certain steel enterprise, technicians found that its circulating water system was in a "big horse pulling small cart" state for a long time due to the selection of too large water pumps, resulting in a high electricity consumption of 320 kilowatt hours per thousand tons of water, far exceeding the industry average level. Through water balance testing and data modeling, the team accurately identified 12 hidden leakage points and calculated that optimizing pressure management can reduce the pipeline leakage rate by 18%.
Diagnosis is not the end point, but the starting point of energy-saving transformation, "said the person in charge of Zhucheng Water Resources Bureau. Based on the diagnostic results, the team customizes a "one household, one policy" plan for each enterprise, covering measures such as efficient water pump replacement, frequency conversion speed regulation technology application, and smart water platform construction. It is reported that the first batch of diagnosed enterprises are expected to save up to 1.2 million tons of water annually, reduce carbon emissions by 960 tons, and shorten the investment payback period for water-saving renovation to within 2 years.
This public welfare service not only reduces costs and increases efficiency for enterprises, but also promotes the construction of a water-saving society. Next, various cities will establish a closed-loop mechanism of "diagnosis rectification follow-up", gradually expanding service coverage to public institutions, residential areas, and other fields, making energy-saving diagnosis a "health examination center" for green development
