4 Reasons To Use Continuous Electro Deionisation For Your Industrial Water


For over fifty years now, Deionisation (also known as De-Min or ion exchange) systems have played a major part in commercial water purification operations. The proven and commonly used technology comes with many benefits and reasons to be the chosen one for your business.

Continuous electro-deionisation (CEDI) is an excellent variant on the process that helps complete water treatment of feed water previously treated through reverse osmosis. The major reason for using this technology is to avoid the harsh chemicals that are typically used in a conventional ion exchange system (e.g. for chemical regeneration of resin beds).

Whereas you can get the same resulting quality water from a conventional deionisation (DI) or CEDI plant, the system has the advantage being fully customisable to meet different business requirements.

To assist you further, let us share with you the top reasons to choose continuous electro-deionisation for your industrial process water treatment.

Reasons To Use Continuous Electro-Deionisation For Your Industrial Water

There are several advantages to using CEDI. First, continuous electro-deionisation does not need the extra steps that are usually involved in other ion exchange treatment processes, such as chemical regeneration or water neutralisation. Moreover:

  1. Continuous electro-deionisation for industrial water has low levels of wastage and offers low operation costs. Additionally, this type of treatment requires little maintenance for its operation. There are no resin membranes to regenerate and most systems can be automated to run with little or no manual input.
  2. The treatment system is compact and has a small footprint. The system does not require two separate units of treatment to be installed and this feature of significantly affects its size, complexity and the system’s overall cost.
  3. Combined with pre-treatment by RO, the continuous electro-deionisation system can achieve more than 99.5 percent removal of salt, decrease the individual ionic species level to parts/billion or even parts/trillion levels. Moreover, CEDI also provides high-purity water with 10 – 18 megohm-cm (around 0.1 – 0.055 micromho/cm conductivity) resistivity.
  4. With the continuous regeneration of ion exchange resins by an electrical current, it diminishes the possibility of improperly or exhausted regenerated resins that contaminate the product water.

Additionally, several reductions in tangible costs also favour the use of a CEDI system, such as reduced labour costs, fewer consumables, lighter maintenance requirements etc. Health and safety at the workplace can also be improved by minimising hazardous chemical use as much as possible.

Why Should You Opt For Continuous Electro-Deionisation For Industrial Water?

If you need high-purity process water for your facility, leaving out the cost and all other problems that come with bulk chemical storage and handling, CEDI is your most cost-effective option. This system is perfect for businesses who need a non-stop water supply at varying quantities, with no downtime.

Similarly, CEDI is well-suited for businesses that need reduction of CO2 and/or TOC, or silica, and also for those who need to reduce water recovery cost and wastage levels, as the high-water recovery rate of the system is one of its strongest advantages.
