Boiler Water Quality Control - Complete Water Solutions

The increasing level of the TDS is known as "cycles of concentration.". This term is used very often in the operation and control of a boiler system. A water supply that contains 175 ppm of TDS in the make-up water could be concentrated 20 times to 3500 ppm. The maximum amount of TDS allowed in a low-pressure boiler is 3500 ppm.
