Scientific initiative to improve water quality at Nghe An Water Supply Joint Stock Company
(Baonghean.vn) - Grassroots scientific initiatives at Nghe An Water Supply Joint Stock Company help improve clean water quality, save costs for the company and supply the market with water products that meet standards.
This scientific work comes from reality.output water qualityof the factories still exist, inadequate. That is, although the output clean water quality indicators all meet the quality standards of the Ministry of Health, the dissolved organic matter indicators are close to the level that exceeds the current standards, always facing the risk of not ensuring quality.
With the water consumption output in 2022 of Vinh City and surrounding areas of about 24.15 million m3, the water supply pipeline network must be periodically cleaned every month with water pumped from the factory.
The amount of flushing water used to clean the network before applying technological equipment improvements to remove dissolved organic substances, contributing to improving the quality of clean water, accounts for about 1% of the water consumption, equivalent to about 241.5 thousand m3/year. With an average clean water price of 10,200 VND/m3, the cost of flushing is very high, averaging up to 2.464 billion VND per year.
Therefore, the Board of DirectorsNghe An Water Supply Joint Stock Companyhas directed the technical department to research solutions to separate and remove dissolved organic substances to improve water quality. When the quality of clean water is improved, the periodic flushing of the pipeline network will be shortened. Thereby saving clean water costs from flushing, saving annual costs.
After improving the technological equipment, the amount of water used for flushing only accounts for 0.5% of the water consumption, equivalent to 120.78 thousand m3. More importantly, after the improvement, not only has the quality of clean water output at the factories been improved, but the cost of water for flushing has also been reduced to only 1.232 billion VND/year.
Thus, with just one initiative in this scientific and technological activity, Nghe An Water Supply Joint Stock Company has saved and benefited the Company more than 1.2 billion VND per year; at the same time contributing to improving the quality of clean water produced and supplied by the Company.
