Highly Purified Water (HPW)

HPW stands for “Highly Purified Water,” which translates to “Hochreines Wasser” in German.

HPW must be free from impurities and meet specific quality criteria regarding physical, chemical, and microbiological parameters. These include conductivity, total microbial count, endotoxins, dissolved solids, organic compounds, particle size, and other critical factors.

The production of highly purified water typically involves a combination of various water treatment processes, including reverse osmosis, ion exchange, distillation, filtration, and disinfection. These processes are designed to remove contaminants from the water, ensuring high purity and compliance with strict quality standards.
