Boiler Feedwater Treatment (Part II): Water Treatment Fundamentals …

For example if a particular boiler can tolerate 500 ppm maximum dissolved solids, and the feedwater contains 50 ppm, it can be concentrated only about 10 times. This means that for every 100 pounds of water fed to the boiler about 10 pounds of boiler water must be blown down to keep the dissolved solids from exceeding 500 ppm.
