Guangdong Metrology Institute applied water balance test to measure water for large water users

[China Instrument Network Instrument Industry] Recently, Guangdong Metrology Institute conducted water balance tests on hundreds of water users with monthly water consumption of over 5,000 tons, including Guangzhou Hitachi Elevator Co., Ltd., Panyu Zhujiang Steel Tube Co., Ltd., and Guangzhou No.6 Middle School. It solves the "water muddle" problem of leakage and over-consumption and effectively promotes the construction of a resource-saving society.

The Guangdong Metrology Institute conducted a comprehensive system of on-site investigations to ascertain the status of water sources, water pipe networks, water facilities, and water measuring instruments used by the company. The entire pipe network was measured for lost water loss, and repair measures were taken to block the leaks. If there is a measurement deviation of 24% between the total water meter and the water meter of Guangzhou Siemens Transformer Co., Ltd., after calculation and analysis, it is found that the underground pipeline of the company has leaked more than 30 cubic meters per day. After the restoration, the actual water consumption rate of the company reached more than 98%.

After at least 8 consecutive days of testing, the “Water Balance Test Report” including water balance testing methods, basic user water usage, water balance tables for each unit, calculation of main water indexes, and recommendations and evaluation of water rationalization will be issued to assist users. Identify potential for water conservation, equip or improve water measurement instruments and ledgers, prepare water supply system network diagrams and water measurement network diagrams. Such as Guangzhou Bayer Material Science and Technology Co., Ltd. launched the water balance test, improved the water meter installation and water management system, the unit product water consumption dropped from 3.03 m3 / t to 2.87 m3 / t.

The provision of solid data data facilitates the administrative department to grasp the macro-level water consumption in the region and formulate more scientific and rational water use, water-saving planning and water quotas. Such as helping Dongguan City, Guangdong Province to develop the beer industry water quota standards, based on the water balance test data collection, through the water-saving technical transformation, the unit product water intake control in (4.0 -5.2) m3/kL, more than the domestic advanced level (8.0 m3 / KL). Helped Dongguan City to formulate a water quota standard for the papermaking industry. Through water-saving technological upgrading, the quota for papermaking water withdrawal was reduced from 25 m3/t to 16.9 m3/t, saving water consumption by 32.4%.
