Continuous Electrodeionization (CEDI) System for Ultrapure Water — AQUALITEK

High-Purity Performance

AQUALITEK's continuous electrodeionization (CEDI) system for ultrapure water produces stable, high-resistivity water (Type I/II quality) without chemical regenerants. Combining ion-exchange membranes and ion-conductive resins with an applied electrical field, our CEDI modules continuously remove ionic contaminants while maintaining ultra-low total organic carbon (TOC) and silica. Ideal for semiconductor fabs, pharmaceutical manufacturing, power plants, and analytical laboratories.

Engineered for Efficiency and Reliability

Designed for low operating cost and long service life, AQUALITEK CEDI systems feature energy-efficient power supplies, optimized flow paths, and automated control logic. Continuous operation eliminates downtime for chemical regeneration, reducing maintenance and labor. Remote monitoring and smart diagnostics provide real-time performance data and proactive alerts to maximize uptime.

Complete System Integration

We deliver turnkey solutions that integrate pretreatment (RO, water softening, filtration), CEDI core units, and post-treatment polishing. Skid-mounted, compact designs simplify installation and reduce footprint. Modular CEDI stacks allow capacity scaling from pilot to full production while maintaining consistent ultrapure output.

Compliance, Quality and Global Service

AQUALITEK, headquartered in Guangzhou, China, adheres to strict manufacturing and quality control standards. Our systems are factory-tested and documented for regulatory compliance. Global after-sales support, spare parts, and service contracts ensure reliable operation wherever your facility is located.

Applications and Value

Typical applications include semiconductor rinse water, pharmaceutical WFI polishing, boiler feedwater in power generation, battery and electronics manufacturing, and research labs. The result: lower operating costs, reduced chemical usage, and consistently reproducible ultrapure water quality.

FAQ:

Which chemicals are required for regeneration?

Softening uses NaCl. Demineralization uses HCl or H₂SO₄ for cation resin and NaOH for anion resin.

How do I know when to add salt to my softener?

Check the brine tank monthly. Modern systems often alert you automatically when salt levels are low.

Can I use AQT’s water treatment systems for seawater desalination?

Yes! We provide seawater desalination systems using advanced reverse osmosis (RO) technology, specifically designed to convert seawater into fresh, drinkable water. These systems are ideal for coastal communities, marine applications, and industrial desalination projects.

How long does a water softener system last?

Most systems last 10–15 years with proper maintenance. Resin beads may need replacement after 8–10 years.

Is softened water safe to drink?

Yes, but those on low-sodium diets should consider potassium-based softeners or install a separate drinking water filter.
