  • Water chloramination control system
    Patent number: 6881583
    Abstract: A water chloramination control system compares the concentration of aqueous higher chloramines to aqueous ammonia to optimize the ratio of added ammonia to chlorine. Aqueous ammonia concentration is measured by conversion to monochloramine which concentration is determined spectroscopically. Higher chloramine concentration is measured by a reaction producing free iodine which concentration is also determined spectroscopically. The higher chloramine to ammonia ratio is used to control ammonia feed to the water. Problems associated with excess chlorine, or excess ammonia, are avoided.
    Type: Grant

    Date of Patent: April 19, 2005

  • Spectrophotometric monitoring of multiple water treatment performance indicators using chemometrics
    Patent number: 5242602
    Abstract: The present invention is directed to a novel method for analyzing aqueous systems to simultaneously quantify the concentrations of multiple active or inactive treating components which may be contained therein. The method comprises determining the absorbance or emission spectrum of the components in the aqueous system over the wavelength range of from 200 to 2500 nm, and then applying chemometrics algorithms to extract and analyze features in the spectrum that are specific to the qualitative and quantitative concentrations from the specific components to simultaneously determine the concentrations of the components.
