Mountain spring definition
First of all, the water source of the spring water must come from a specific protected mountain area, there is no pollution in the area, and there is no other pollution into the water source area. Therefore, if the water intake point of the factory does not meet this requirement, it is not a real mountain spring water.
Secondly, the water source itself needs to pass the self-purification of the mountain itself, and it contains a certain amount of minerals. The drinking water from natural non-polluted lakes and reservoirs, due to the lack of self-purification and mineralization, has low mineral content and water source. Not clean enough, it is often necessary to do simple filtration manually to drink, so if the water source is not from the mountains, it is not true mountain spring water.
The spring water equipment is a kind of solution separation based on the pressure difference between the two sides of the membrane. Based on the principle of mechanical screening, the pressure is usually 0.2MPa--0.6MPa, and the separation pore size is 1nm--0.1μm. It can be widely used in substances. Separation, concentration, purification. Ultrafiltration process has no phase conversion, normal temperature operation, especially suitable for the separation of heat sensitive substances, and has good temperature resistance, acid and alkali resistance and oxidation resistance. It can be used continuously for a long time under conditions of 60 ° C and PH of 2-11.
