When steam condenses, condensate is formed. In most processes however a large part of the steam is lost in the process or in the final product and does not return as condensate.
The condensate which is formed is in most cases already of a good quality because it contains little to no salts. Moreover, it usually has a high temperature of e.g. 90 - 100 ° C and it is therefore valuable to start re-using. In some cases it is necessary to polish the condensate to bring it back to a level comparable to that of the fresh ultrapure water.
Usually ion exchange is used in this context.
Water-link has experience with condensate treatment using techniques such as mixed bed polishing.
