Patent number: 11772998Abstract: Methods of employing peroxycarboxylic acid compositions for the prevention of scale formation and in some embodiments the removal of existing scale are disclosed. In particular, the scale inhibition properties of percarboxylic acids of varying chain lengths including C1-C22 provide effective scale inhibition and scale removal or destruction. Methods of employing peroxycarboxylic acid compositions for scale inhibition and/or removal are particularly well suited for treating fluids intended to flow through pipes, namely in the energy industry, water and paper industries, etc. The methods provide suitable scale inhibition replacements and/or additives to known scale inhibitors.Type: GrantFiled: May 20, 2021Date of Patent: October 3, 2023Assignee: ECOLAB USA INC.Inventors: Ramakrishnan Balasubramanian, Brian Epps, Junzhong Li, Richard Staub, Victor Keasler

Patent number: 10081561Abstract: The invention provides methods and compositions for reducing the malodorous sulfide gas released by a wastewater treatment system. The method preserves the vitality of waste consuming organisms within the system. The method comprises the steps of: determining the SRP PAA demand of the system, determining the aerobic PAA demand of the system, and adding a composition in an amount such that it is in excess of the SRP PAA demand but is below the aerobic PAA demand. Even though the composition increases the amount of sulfates within the wastewater it reduces the amount of SRP which prevents the malodorous sulfite gas release. The composition comprises at least one percarboxyacid.Type: GrantFiled: April 24, 2017Date of Patent: September 25, 2018Assignee: Ecolab USA Inc.Inventors: Gary L. Champion, Victor Keasler, Robert J.
