Method for treating power plant heater drain water

摘要

Oxygen is mixed with heater drain water of power plant which contains fine particles of iron oxides such that the concentration of the dissolved oxygen in the heater drain water after the mixing of oxygen is in a range from 1 mug/liter to 20 mug/liter. The obtained heater drain water after oxygen mixing is filtered through a filter such as a hollow fiber filter to remove fine particles of iron oxides.
