Deionized Water Equipment Introduction
Deionized water equipment is a special water treatment system that removes ionic impurities from raw water through physical and chemical methods to produce deionized water. It is mainly divided into three mainstream types: ion exchange type, EDI electrodeionization type and electrolytic type. Core components include pretreatment system, desalination unit and intelligent control system. The effluent resistivity ranges from 1 to 18.25MΩ·cm, which can be flexibly adjusted according to application requirements. It adapts to various water sources such as municipal tap water and low-hardness groundwater, with production capacity covering 0.1 to 500 tons per hour. With years of in-depth experience in water treatment, Xi'an DIEN Water Treatment can customize dedicated deionized water equipment for industrial, laboratory and other scenarios, balancing practicality and cost performance.
Working Principle of Deionized Water Equipment
Deionized water equipment follows the general working logic of "Pretreatment + Deep Desalination", while the desalination principle varies by type. The ion exchange type uses cation and anion exchange resin to adsorb ions in water, and the resin can be recycled after chemical regeneration when saturated. The EDI type integrates electric field driving and membrane separation technology to realize directional ion migration and automatic resin regeneration without chemical agents. The electrolytic type decomposes water molecules through electrolysis to remove ions simultaneously. In the pretreatment stage, quartz sand and activated carbon filtration are adopted to remove suspended solids, residual chlorine and other impurities, laying a foundation for deep desalination. Xi'an DIEN Water Treatment optimizes process parameters to improve desalination efficiency and operational stability.
Advantages of Deionized Water Equipment
Deionized water equipment features core advantages that meet the demands of various industries: First, remarkable desalination effect, efficiently removing over 99% of ionic impurities and maintaining stable water quality to meet industry water standards. Second, strong compatibility, adapting to diverse raw water quality and fully covering scenarios from small laboratories to large factories. Third, convenient operation and maintenance. Equipped with PLC intelligent control system, it realizes fully automatic operation and real-time parameter monitoring, reducing labor costs. Fourth, green and energy-saving. EDI and electrolytic types require no chemical regeneration with no acid-base wastewater discharge; ion exchange resin can be recycled. Customized models from Xi'an DIEN Water Treatment further optimize energy consumption and lower operating costs.
Application Fields of Deionized Water Equipment
Deionized water equipment is widely used in multiple core fields: In industry, it is used for boiler make-up water, electroplating cleaning and chemical reaction water to prevent equipment scaling and improve product quality. In scientific laboratories, it supports experimental analysis and sample preparation to ensure accurate experimental data. In the pharmaceutical industry, it is applied to medical device cleaning and pharmaceutical formulation, complying with GMP standards. In the electronics industry, it is used for component cleaning to increase product qualification rate. It is also suitable for food processing, new energy, environmental testing and other scenarios. Xi'an DIEN Water Treatment optimizes equipment configuration according to industry characteristics to precisely match water demand.
