What are the pH and conductivity of various types of water in chemical production? Everyone is welcome to discuss

In chemical process water and wastewater, the composition of the water (or degree of pollution) varies greatly. General chemical water treatment (pure water) and boiler feed water have the lowest conductivity, while the conductivity of condensate recovered from various steam processes is slightly higher (when the level of contamination is low). For tap water, the quality depends on that of the water source from which it is drawn; generally, rivers in areas with high levels of natural precipitation have low conductivity, while rivers and groundwater in arid regions with low natural precipitation have higher conductivity. By concentrated water, does it refer to the water that results from membrane treatment? That also depends on the composition of this concentrated water; generally, a high salt content leads to a high conductivity. However, in the case of concentrated water obtained from certain special recovery processes (such as those involving organic substances), since these organic substances may not exhibit significant ionization, the conductivity might not be high either.
