Continuous Electrodeionization (CEDI) System for Ultrapure Water — AQUALITEK
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.
Why Choose AQUALITEK
AQUALITEK combines engineering expertise, customizable design, and manufacturing excellence to deliver high-performance CEDI solutions tailored to your application. Contact us for specification sheets, pilot testing, and lifetime support to ensure your ultrapure water needs are met with confidence.
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.

Correct chemical dosing location is critical to the safe and efficient operation of an RO system. Scale inhibitors and reducing agents are two essential chemicals commonly used to protect RO membranes, but they must be injected at the correct points in the process. This article explains where these dosing points are typically located and why their placement matters.
Why Extended Flushing Without Tank Filling Is Required During Initial RO System Startup| Insights by AQUALITEK
During the initial startup of a new RO system, operators are often instructed to flush the system for an extended period without sending permeate to the product water tank. This practice is not optional—it is essential for system safety, membrane protection, and long-term water quality stability. This article explains the technical reasons behind this critical startup procedure.
