Can the water quality of Haier filter 603-5a be drunk? The water quality is 259. isn't the drinking water below 50! If the value detected by tds tester is 259, it is said that the impurity content in clear water is almost the same as that in urban tap water, it is not recommended to drink.The value of the TDS Pen is in ppm, which means one in a million, or how many mg per liter (because: L = kg ). Different water, its PPM value is different. Here are the TDS values of several different water types:Roshui (I .e. pure water): 0-10ppm (if it is from the northern mainland, the TDS value is not necessarily less than 10 or more than 10 for practical groundwater .).Tap water: 50-1000ppmSurface water: 40-2000ppmSaltwater: 2000-5000ppmSea water: 2000-4200ppmPure water refers to H2O without impurities.From an academic point of view, pure water, also known as High pure water, refers to water with extremely high chemical purity, which is mainly used in biology, chemical industry, metallurgy, ae

The water from the CASS process in the design of water reuse in the community should be followed by a coagulation sedimentation tank, and, if so, how to design their water inflow? The effluent of the normally operated CASS pool can reach the water quality standard of direct discharge,Is it necessary to prepare for reuse after precipitation and filtration?!You can add an intermediate pool behind the CASS pool,Used to connect CASS and subsequent processes,The volume of the intermediate pool is determined according to the amount of skimming of CASS's apostrophe,The system runs stably.The subsequent water intake is no problem according to the design specifications.The integrated valve-free filter is directly installed behind CASS.
