  • Method for producing a biocide
    Patent number: 11812741
    Abstract: A method for producing a biocide from a hypochlorite oxidant and an ammonium salt is provided. The method focuses on preventing and/or reducing the presence of excess ammonium. The molar ratio of ammonium to hypochlorite is less than 1:1. In a preferred embodiment, the method includes monitoring the conductivity of the biocide to optimize the ratio between the hypochlorite oxidant and the ammonium salt. The optimum ratio is that at which the conductivity has a local maximum.

  • System and method for monitoring process water treated with a biocide using an oxygen sensor
    Patent number: 11427482
    Abstract: A system and method for monitoring process water treated with a biocide is provided. The system includes a biocide feeding unit and a dissolved oxygen sensor. The dissolved oxygen sensor works in two modes, a biocide feeding mode and a background mode, and alerts an operator when the dissolved oxygen value indicates a fault in the system. A drop in dissolved oxygen during feeding can indicate faulty production of biocide or biocide degradation, both of which can lead to unwanted disinfection by-products.
