what is water purification plants for laboratories
Our laboratory water purification equipment is key to ensuring the accuracy and robustness of experimental results. These devices remove impurities, microorganisms, and ions from water through various technological means to produce purified water that meets specific needs.
key technology
- Pre treatment filtration: Using pressure drive, impurities in water are preliminarily filtered out through filter cartridges such as PP filter cotton, coconut shell activated carbon, compressed granular carbon, etc.
- Reverse osmosis (RO) technology: using a semi permeable membrane to separate dissolved solids, salt ions, and other pollutants from water.
- Ion exchanger: removes ions and impurities from water through ion exchange movement.
- UV sterilization: using ultraviolet light to kill bacteria and viruses in water.
