The Hydra Premium Purity DI System is a pre-assembled cartridge system that provides deionized water using a staged filtration process. Water purification is provided using a 3-step process. Stage (1) removes particles greater than 5 micron, chlorine, and organics. Stages (2 & 3) are deionizers designed to remove dissolved organics and silica to trace levels. These premium grade resins are specially designed and processed to shed low levels of organics, adding no more than 10 ppb TOC. The Hydra Premium Purity DI series includes all cartridges and resistivity light for a total turnkey system. The system configuration uses mixed bed cartridges for applications requiring 10 MΩ-cm water quality.
