Publication number: 20230276800Abstract: Methods and systems for temperature-controlled, on-site generation of peracids, namely peroxycarboxylic acids and peroxycarboxylic acid forming compositions are disclosed. In particular, methods for using an adjustable biocide formulator or generator system overcome the limitations of temperature on the kinetics of the peracid generation and/or peracid decomposition inside an adjustable biocide formulator or generator system. The methods include the controlling of the temperature of at least one raw starting material, namely water, to improve upon methods of on-site generation of peracids. The methods allow for the generation of user-selected chemistry without regard to the ambient temperatures of the raw starting materials and/or the biocide formulator or generator system.Type: ApplicationFiled: May 8, 2023Publication date: September 7, 2023Inventors: Brandon Herdt, Richard Staub, Thomas C.

Patent number: 9980626Abstract: Dispensing techniques utilize existing fluid to dispense a solid block of chemical product concentrate. The solid chemical product concentrate may include, for example, detergents, disinfectants, sanitizers, rinse agents, or other cleaning agents. The dispenser monitors and controls the concentration of the chemical product in a use solution. When the concentration of the use solution falls outside of a target range, the dispenser routes existing fluid from within the system to the dispenser, where it interacts with and dispense a solid chemical product concentrate, thus raising the concentration of the chemical product in the use solution. In a dishmachine application, the existing fluid may include post wash or rinse fluid from the dishmachine, or may include use solution from a sump, tank, or other use solution storage container.Type: GrantFiled: October 29, 2014Date of Patent: May 29, 2018Assignee: Ecolab USA Inc.Inventors: Jared R.
