Mineral water equipment process
特点： Features of mineral water equipment :
Ability to remove chlorinated organics and other toxic and harmful substances;
The microbial index is zero, extending the shelf life of mineral water;
Have good look and feel indicators to make the taste better;
While removing toxic and harmful substances, the essential trace elements and inorganic salts of the human body in water are retained.
Ultrafiltration is a solution separation process based on the pressure difference between the two sides of the membrane and based on the principle of mechanical sieving. The pressure is usually 0.2MPa--0.6MPa, and the separation pore size is 1nm--0.1μm. Separation, concentration and purification. Ultrafiltration process has no phase transformation, and operates at room temperature. It is particularly suitable for the separation of heat-sensitive substances. It has good temperature, acid and alkali resistance and oxidation resistance. It can be used continuously for a long time under 60 ¡ã C and pH 2-11. .
Ultrafiltration (UF) is the key equipment of electrophoresis coating line. Tube-type ultrafilter and roll ultrafilter are widely used in electrophoresis line. Its main purpose for electrophoresis is to:
① Obtain deionized water and lacquer solvent, co-solvent, etc .;
② Provide spray water for swimming parts;
③ Recover the paint liquid carried on the electrophoresis parts to save the amount of paint liquid;
负荷。 ④ Save pure water for washing, and help maintain the chemical balance of the electrophoresis tank, reduce the waste water treatment load discharged after pure water cleaning.
The tubular ultrafilter has good circulation, is not easy to be blocked, and is easy to clean. It is suitable for applications such as electrophoretic paint recovery, fruit juice concentration, silica sol production, and oil-water separation.
Roll-type ultrafilters have:
① Large membrane area;
② compact body structure;
③ Simple installation and maintenance;
④ occupy less land;
⑤ Compared with other ultrafilters, it has low energy consumption and other advantages;
However, the pretreatment requirements are higher than those of tubular ultrafilters.
