According to Ningbo municipal water conservancy bureau, 36 water supply works administered by 23 water supply enterprises have changed their disinfectant from liquid chlorine to sodium hypochlorite.
Liquid chlorine is the most common disinfectant adopted by water supply enterprises. However, both liquid chlorine and its storage tank should be on highly guard for they are dangerous.
To completely eliminate such security risks, since 2014 Nibo municipal government has advocated water supply enterprises to use sodium hypochlorite as water disinfectant.The working principle of sodium hypochlorite is similar to that of liquid chlorine and both are of good effect. Though using sodium hypochlorite costs higher, it is more safe and more convenient to store. What’s more, it can also improve the taste of water.
At the same time, to ensure the safety of drinking water, Ningbo water supply industry carries out the regular third-part detection of water quality monthly to perfect water quality monitoring work.
