What is steam used for in the desalinated water system?
Thread Content
I see that the desalination system uses steam, and the steam is used to heat the heat exchanger. What is the purpose of this?
The demineralized water system generally does not require heat or generate heat; it is recommended that the owner check the equipment nameplate
Generally, spent steam is used to heat the deionized water, after which the deionized water enters the deaerator in order to save high-quality steam.
The alkali-treated water is heated using a heat exchanger, and the diluted alkali-treated water is used in the anion exchanger for displacement and regeneration
The membrane has a suitable range for medium temperature; in winter, when the raw water temperature is too low, heating is required.
Steam is used to raise the temperature of raw water and desalinated water, as optimal operation and regeneration performance are achieved when the operating temperature of the bed does not exceed 40°C.
It is indeed meant to raise the temperature of the raw water
