CDI (Capacitive Deionization)
A capacitive deionization technology based on the principle that when electricity is applied to the electrodes, the oppositely charged ions pass through the ion membrane and move to the electrode surface for electric adsorption
Features
- Applicable to a wide range of TDSs
- Operation under stable DC voltage with bipolar electrodes
- High Recovery Rate < 95%
- Desalination Rate < 95%
- Operating Temperature < 40℃
- Low energy consumption due to low pressure operation
- Salt rate < 95% (remove ionic substances such as nitrogen, potassium, chlorine, hardness, magnesium, etc.)
- Cost-effective pre-treatment process compared to other technologies
- Electrical stability is ensured due to no electrodes exposed
