  • QCM measurement of scale formation
    Patent number: 11137373
    Abstract: A water hardness mitigation or treatment evaluation system includes a first quartz crystal microbalance cell and a fluid coupling adapted to be fluidly coupled to a pre-treated water to be flowed over a first quartz crystal. A second quartz crystal microbalance cell and a fluid coupling are adapted to be fluidly coupled to a post-treated water to be flowed over a second quartz crystal. A computer processor receives a first frequency data from the first quartz crystal and a second frequency data from the second quartz crystal and based on a difference of frequency over time between the first frequency data and the second frequency data, provides an indication of an effectiveness of a water hardness mitigation or treatment component or system. A method to evaluate and effectiveness of a water hardness mitigation or treatment evaluation system is also described.
