摘要： Method for neutralizing waste water from cleaning of flue gases emitted from power plants, in an aeration basin for waste water, by which at the sump of the absorber or in the outlet pipe of the absorber, the waste water is neutralized with the natural alkality of seawater which is supplied to the absorber and the following aeration basin, continuously to monitor the pH of the waste water, and to add additional alkality, such as in the form of Ca(OH)2, to the sump of the absorber or in the outlet pipe of the absorber, before the water is mixed with the rest of the seawater amount for aeration, should the alkality of the seawater decrease or the sulphur content of the flue gases increase.
