Stacked High-quality Ultrapure Water Reverse Osmosis EDI Module For Water Treatment Veolia EDI stack MK-3
For many years, operators of pure water production systems were trying to find a technology to replace mixed bed ion exchange for final demineralization. The operating cost as well as the complexity and risks associated with acid and caustic regeneration were frustrations to these operators. EDI became established as the innovative alternative solution by reducing operating costs, improving site environmental, health, and safety risk profiles, and producing a continuous and steady supply of pure and ultrapure water.
Production of pure water has evolved from conventional pretreatment with multiple stages of ion exchange in initial and final demineralization to the following membrane based operations,including EDI, that are now considered to be best practice by many customers around the world.
General Description
As part of the E-Cell* electrodeionization product line,the E-Cell MK-3 Stack is designed to:
• Use electrical current to provide ultrapure water for semiconductor fabrication, power generation,solar panel production, and many other heavy industries.
• Deliver premium performance including both the highest levels of product water quality and the lowest energy consumption.
• Minimize cleaning requirements at higher feed water hardness levels using counter-current
operation.
• Be leak free, guaranteed.
• Operate continuously and require no caustic or acid for regeneration of ion exchange resin within the stack.
• Require no brine injection or concentrate re-circulation.
Typical Applications
The product water from the E-Cell MK-3 can be relied upon to meet today’s most demanding ultrapure water applications including:
• Ultrapure water for rinsing of semiconductor chips, solar panels, and other microelectronics
• Demineralized boiler feed water for high pressure boilers found in power plants and other heavy industrial sites
For ease of design and additional confidence in your EDI application, E-Cell performance projections and guarantees are available in the Winflows* software
