Generally, the inlet and outlet water values for EDI systems are adjusted to meet specific purity or ion concentration requirements. Here are some factors typically taken into account:
Ion Concentrations: EDI systems remove or reduce specific ions from water solutions. The ion concentrations in the inlet water determine the outlet water targets. Unwanted ion levels can be reduced while required ion concentrations can be increased.
Application Type: EDI systems can be designed for different application types. Other applications, such as drinking water treatment, laboratory applications, semiconductor manufacturing, and industrial processes, may have varying water quality requirements.
Process Efficiency: The design and operational process of the EDI system determine the inlet and outlet water values. An efficiently designed EDI system can achieve high levels of purity.
Feed Water Quality: The initial quality of the feed water is crucial for the successful operation of the EDI system. If the feed water is highly contaminated or has excessive concentrations of specific ions, it can affect the efficiency of the EDI system.
Operational Parameters: Operational parameters such as temperature, flow rate, electrical current, and voltage influence the performance of the EDI system and dictate the inlet and outlet water values.
In summary, EDI systems' inlet and outlet water values can vary depending on specific application requirements and design parameters. When designing an EDI system, it is customized to meet the particular needs of a project, making inlet and outlet water values project-specific.
