Ultra-pure water, commonly abbreviated as UPW refers to high-quality water purified to exemplary specifications. Essentially, ultra-pure water has very minimal concentrations of impurities and is commonly utilized in laboratories and pharmaceuticals. There are distinct levels of high-purity water but ultra-pure water is specifically characterized by an electrical resistivity of 18.2 MΩ-cm at 25°C.
Typically, ultra-pure water is generated using ultra-pure water systems, which constitute elaborate pretreatment, primary treatment, and post-treatment systems. Numerous technologies have been developed to gratify the continually growing demand for ultra-pure water including electrode ionization, reverse osmosis, and water deionization. The production of UPW is commonly regulated by industry regulators such as the USP, European Pharmacopeia, ASTM, and EPRI.
The RO system, complemented by a bactericidal UV system, serves as crucial pretreatment for the electrodeionization system. To prevent biofilm formation and airborne contamination, the resultant pure water is stored in a polyethylene tank. The purified water undergoes a final treatment, exposing it to UV light radiation and post-treatment cartridges, ensuring the elimination of all organic and ionized pollutants.
Alternatively, a widely embraced ultra-purification method involves a series of steps, starting with activated carbon filters, pre-chlorination, antiscalant dosing, and cartridge filtration for effective pretreatment. Subsequently, the water undergoes multi-stage RO filtration, culminating in a polishing phase with an electrodeionization system, resulting in the production of Ultra-Pure Water (UPW).”
An ultra-pure water system is essentially a multi-stage water purification system deployed to eradicate all or nearly all pollutants residing in raw water. Customarily, ultra-pure water systems eliminate contaminants in multi-stage processes involving reputable technologies like reverse osmosis, ion exchange, UV water sterilization, and electrodeionization.
