Abstract: 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.

Abstract: Low foaming, highly acidic peroxycarboxylic acid sanitizing compositions are disclosed as having both improved antimicrobial efficacy in comparison to conventional peroxyoctanoic acid and peroxyacetic acid compositions for sanitizing applications. The compositions include a combination of a low-foaming surfactant and an aluminum sulfate (or other metal salt) defoaming agent that is compatible with the highly acidic peroxycarboxylic acid sanitizing compositions. In particular, the sanitizing peroxycarboxylic acid compositions are also low odor and low/no VOC dual functioning acid wash and sanitizing compositions.

Abstract: Methods for the use of peracid compositions having decreased hydrogen peroxide concentration for various water treatments, including oil- and gas-field operations, and/or other aseptic treatments are disclosed. In numerous aspects, peracetic acid is the preferred peracid and is treated with a peroxide-reducing agent to substantially reduce the hydrogen peroxide content. Methods for using the treated peracid compositions for treatment of drilling fluids, frac fluids, flow back waters and disposal waters are also disclosed for improving water condition, reducing oxidizing damage associated with hydrogen peroxide and/or reducing bacteria infestation.
