Overall Overview

Ultra-pure water refers to water with very low levels of impurities, including: ① inorganic ionic impurities such as Ca, Mg, Na, K, Fe2+, Fe3+, Mn, Al, HCO, CO, SO, Cl, NO, NO, SiO, PO, etc.; ② organic matter such as alkylbenzene sulfonic acid, oil, organic iron, organic aluminum, and other hydrocarbons; ③ particles such as dust, iron oxide, aluminum, colloidal silicon, etc.; ④ microorganisms such as bacteria, plankton, and algae; ⑤ dissolved gases such as N2, O2, CO2, H2S, etc. The content of ionic impurities in ultra-pure water is measured by the water's resistivity value. Theoretically, only H+ and OH- ions participate in conductivity in pure water. At 25°C, the resistivity of ultra-pure water is 18.3 (megohm·centimeter), generally ranging from 15 to 18 (megohm·centimeter). Our company can customize and produce according to different needs, ranging from 1T/H to 1000T/H.

Product Categories

Based on the varying process water requirements across different industries and the original water quality, customizable ultra-pure reverse osmosis systems can be provided to meet the water standards.

Ultra-pure Water Equipment Technology

Ultra-pure water, which is difficult to achieve through conventional processes, undergoes four major steps: pretreatment, reverse osmosis technology, ultra-purification, and post-treatment. It includes multi-stage filtration, high-performance ion exchange units, ultra-filtration filters, ultraviolet lamps, TOC removal devices, EDI (Electrodeionization) salt removal units, and polishing mixed bed units, resulting in a resistivity of 18.25 MΩ·cm (at 25℃).
