Description

Technical Field

[0001] The utility model relates to the technical field of wastewater recycling, in particular to a wastewater recycling module of a high-efficiency reverse osmosis ultrapure water system. Background Art

[0002] The high-efficiency reverse osmosis ultrapure water system is a high-end water treatment facility that integrates modern membrane separation technology with advanced water treatment processes. Based on reverse osmosis (RO) technology, the system uses a high-pressure pump to pressurize raw water to a certain pressure, forcing water molecules through a reverse osmosis membrane with a pore size of only 0.0001 microns. Most impurities, such as dissolved solids, colloids, microorganisms, organic matter, and heavy metal ions, are trapped on one side of the membrane, achieving deep water purification. During the reverse osmosis process, the salt content and osmotic pressure in the water increase as the water flows across the membrane surface. When the osmotic pressure reaches the pressure of the booster pump, some water cannot pass through the membrane, resulting in wastewater. To prevent clogging of the RO membrane, the system uses backwashing technology to promptly flush the membrane, and this wastewater is discharged.

[0003] Many ultrapure water systems generate wastewater that is discharged without effective treatment, resulting in a significant waste of water resources and potentially posing a threat to the environment. While some wastewater is used for low-quality purposes like flushing toilets, this limited and inefficient use fails to fully tap the wastewater's potential value.
