In the realm of water treatment, Continuous Deionization (CDI) has emerged as a powerful and efficient technology, offering a sustainable alternative to traditional methods. CDI utilizes ion exchange resins to remove dissolved salts from water, but unlike conventional deionization systems, it continuously regenerates the resins using electricity, eliminating the need for chemical regeneration.
Understanding the Process:
CDI systems consist of multiple compartments filled with ion exchange resins. As contaminated water flows through the system, the resins capture dissolved ions, effectively removing salts. This process is driven by an electric field that attracts ions towards electrodes within the compartments.
The magic of CDI lies in its continuous regeneration. Unlike traditional ion exchange systems that require chemical regeneration, CDI utilizes electricity to reverse the ion exchange process, releasing captured ions and restoring the resins to their original state. This cycle repeats continuously, ensuring uninterrupted water purification.
