ABSTRACT:
A steam stripping method for the softening of a feedstream of water including the steps of passing the feedstream of water into intimate contact with uncondensed steam such that the steam elevates the temperature of the feedstream of water, increasing the pH of the feedstream of water, reacting the feedstream of water with the steam so as to produce uncondensed steam byproducts and liquid byproducts, and passing the liquid byproducts through a filter so as to remove solids from the liquid byproducts. The steam is reacted with the feedstream of water at a rate of one pound of steam per ten pounds of feedstream water. A quantity of magnesium hydroxide can be added to the feedstream of water so as to initiate silica crystal formation. The liquid byproducts can pass through a bed of aluminum prior to the step of passing through a filter so as to reduce a silica content of the liquid byproducts. In the feedstream of water, a bicarbonate component is converted into a carbonate component at temperatures of less than boiling. Carbon dioxide is released as an uncondensed steam byproduct.
