Introduction to Water Purification
Clean water is necessary for health, food production, data centers, and more. A water application that receives less attention, however, is sensitive manufacturing processes that affect electronics, pharmaceuticals, and power worldwide. While desalination and other technologies advance with the help of SCR power controllers, one technology in particular is changing the landscape of the water purification industry.
Continuous Electrodeionization, or CEDI, is a technology that uses electricity (controlled by DC power controllers) and self-regenerating, ion-exchanging resins to purify water without the use of chemicals. Formally referred to as electrodialysis and capacitive deionization, these groundbreaking technologies enable factories and precise systems to use ultra-pure water for sensitive processes.
The process is simple. Water, often from a river or the ocean, is first run through a general filtration system, such as an RO (Reverse Osmosis) system. The water is then transferred through a CEDI deionizer system to remove ions and become ultra-pure before usage in sensitive processes.
CEDI technology is used in various industries. Deionized water feeds boilers to turn turbines in the power industry. CEDI technology creates ultra-pure water for semiconductor processes. CEDI filters also assist in hot water sanitization processes of the pharmaceutical industry. Smaller CEDI units are used in labs and hospitals for pure water for tests and equipment.
With the help of Control Concepts DC power controllers, CEDI technology enables clean water for industry processes around the world.
The Right Power Controllers for Water Purification
Control Concepts controllers are engineered for industrial durability and long-term reliability. Features such as soft-start capability, constant current control with current limit up to 600 V compliance voltage, advanced diagnostics, and overcurrent protection, as well as ground current monitoring, help improve system stability while protecting electrical equipment from unnecessary stress.
