Can the water produced by ultrafiltration machine meet the standard of drinking water?
Personally, I think the ultrafiltration machine should only filter most impurities. According to the different water quality in different places, if the TDS value of local water is around 200, it can be directly drunk for a long time. More than 300 use ultrafiltration machine, it is recommended not to drink or drink less raw water. I think the machine that can drink directly is the filter element of RO membrane. As for the TDS value, the United States is 30, the international standard is 50 and the European standard is 70.
