when nongfu spring started from Qiandao lake, the source water quality was good. After factory processing, although the trace elements and minerals in the water have been treated almost, the only tds is between 1 and 3 mg/L, but it does not affect that it accounts for the word "natural". Later, the water in Nongfu Spring sold better and better, and the water in Qiandao Lake was not exploited enough, and factories were built on various hills one after another. Because it produces natural water, it does not need to meet the standards of natural mineral water. Needless to say, the price of Nongfu Spring is affordable for ordinary people, the production process is online, it is also a national brand, and food safety is also being carefully controlled. In a word, Nongfu Spring is not natural mineral water, but its water quality is online, suitable for ordinary people to drink.
Dinghu Spring is also natural water, but Dinghu Spring only makes natural spring water. The water source of Dinghu Spring is Dinghushan, a national nature reserve in Zhaoqing, Guangdong, and the geological environment is very good, so it is easy to produce good water in such a place. As the first drinking water enterprise in China to explicitly put forward and produce the category of "natural mountain spring water", after more than 1 years of process exploration, it has developed a unique natural mountain spring water treatment process with "natural dense filtration" technology as the core, and won the national invention patent, which is one of the core competitiveness of Dinghu Spring brand. The water quality is naturally very good. If I had a choice, I would choose Dinghushan spring water.
