Description of Boiler Feed Water Treatment System

Depending on the different quality of raw water, boiler water treatment may adopt the desalination process of ultrafiltration or traditional filtration equipment + reverse osmosis treatment + ion-exchange or EDI system. When used as the pretreatment system, reverse osmosis can remove ions in more than 98%. Depending on the quality of raw water and various requirement of the boiler, as a powerful desalination system, the ion-exchange system adopts combination of cation bed, ion bed and mixed bed or single pass mixed bed or double pass mixed bed to meet the boiler feed water requirement. Compared with traditional ion-exchange method, the reverse osmosis system removes the salt completely, so it can prolong the regeneration period enormously. This technology boasts steady working, ease of operation, high-level automation, low running cost and less environmental influences.
