Underneath, we analyze the primary roles, features, and working principles of NEWater’s ultra-pure water systems.

➣What is Ultra-Pure Water?

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.

➣What is an Ultra-Pure Water System?

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.

This process ideally commences by converting tap water into pure water using reverse osmosis/EDI water systems. The reverse osmosis system in conjunction with a bactericidal UV system is primarily utilized as pretreatment for the electrodeionization water system. To mitigate the formation of biofilm and airborne contamination, pure water is reserved in a polyethylene tank. Finally, the purified water is subjected to UV lamp radiation and post-treatment cartridges, which ensure all organic and ionized pollutants are eradicated.

The other popular water ultra-purification process involves the use of activated carbon filters, pre-chlorination, antiscalant dosing, and cartridge filtration as pretreatment. The water is then subjected to multi-stage RO filtration before being polished with an electrodeionization system to produce UPW.

Their typical configuration has the reverse osmosis system deployed prior to the electrodeionization water system.

As such, the feed water is first filtered using high-rejection reverse osmosis membranes, which eliminate over 99% of dissolved solids. The reverse osmosis permeate harvested is then injected into the EDI water system. The purity levels of the RO water/permeate are characteristically moderate hence it is often categorized as Type III water. The EDI system completely eliminates the ionized constituents harbored by the RO water to generate high-purity water at 18.12 MΩ·cm.
