1: pretreatment - reverse osmosis - purification tank - ion exchanger - UV lamp - pure water pump - water point
2: Pretreatment - primary reverse osmosis - secondary reverse osmosis (positive charge reverse osmosis membrane) - purification tank - pure water pump - UV lamp - water point
3: Pretreatment - reverse osmosis - intermediate tank - intermediate pump - EDI unit - purification tank - pure water pump - UV lamp - water point
4: pretreatment→ultraviolet sterilizing device→first-level RO device→secondary RO device→intermediate water tank→EDI device→deoxidation device→nitrogen sealed pure water tank→except TOC UV device→polishing mixed bed→ultrafiltration device→water point
Ultrapure water system reverse osmosis (membrane separation) method ultrapure water manufacturing technology
Reverse osmosis is the separation of the solvent (usually referred to as water) in the solution through a reverse osmosis membrane (a semi-permeable membrane) with sufficient pressure in the opposite direction to the permeation direction. Separation can be carried out using a reverse osmosis method that is greater than the osmotic pressure. , purification and concentration of the solution. The primary separation target for reverse osmosis membranes is the range of ions in the solution.
