EDI water filtration device

High-Efficiency EDI Water Purification System for Industrial and Laboratory Applications

Discover the advanced Electrodeionization (EDI) water filtration device designed to deliver ultra-pure water consistently and sustainably. This state-of-the-art EDI system combines reverse osmosis (RO) pre-treatment with continuous deionization technology, making it ideal for industries requiring high-purity water such as pharmaceuticals, semiconductor manufacturing, power generation, and scientific research. Engineered by Foshan Hongjun Water Treatment Equipment Co., Ltd., a trusted name in water purification solutions, this machine ensures reliable performance with minimal environmental impact.

Key features include uninterrupted operation, automatic control capabilities, elimination of chemical regeneration processes, and a compact design that saves valuable space. Unlike traditional ion exchange systems, this EDI water treatment solution requires no acid or alkali for maintenance, reducing operational costs while enhancing safety. With a recovery rate of up to 95%, it maximizes water efficiency—critical for facilities seeking sustainable water management practices. The system also minimizes downtime due to regeneration cycles, ensuring consistent output quality for critical applications.

Technical specifications demonstrate exceptional purity: total dissolved solids (TDS) below 25 mg/L as CaCO₃, hardness less than 0.1 mg/L as CaCO₃, silica content under 0.5 mg/L, TOC (total organic carbon) below 0.5 mg/L, and residual chlorine levels below 0.05 mg/L. The pH range is maintained between 5–9, suitable for most industrial processes. Additionally, iron, manganese, and hydrogen sulfide concentrations are kept below 0.01 mg/L, ensuring compatibility with sensitive equipment and processes. Designed for inlet pressures ranging from 30 to 100 PSI, this unit supports flexible integration into existing infrastructure.

This EDI purification system is widely used in laboratories, cleanrooms, boiler feedwater preparation, and process water needs across food & beverage, electronics, and healthcare sectors. Its ability to produce stable, high-quality water without manual intervention makes it a preferred choice for automated production lines and remote monitoring environments. Whether for single-point use or large-scale installations, the system adapts seamlessly to varying flow rates and water source conditions.

Users appreciate its low maintenance requirements, energy-efficient operation, and long-term cost savings compared to conventional methods. Many have reported improved product consistency and reduced risk of contamination in downstream processes. The modular design simplifies installation and scalability, allowing businesses to expand capacity without significant infrastructure changes.

Common questions often revolve around the system’s durability under fluctuating feedwater quality, ease of integration with existing RO units, and how it compares to mixed-bed ion exchange systems. The answer lies in its robust internal structure, which continuously regenerates ion-exchange resins using electricity rather than chemicals, eliminating the need for periodic chemical dosing. It also performs well in environments where water chemistry varies seasonally or due to local supply issues.
