  • Methods for cleaning industrial equipment with pre-treatment
    Patent number: 8398781
    Abstract: A method of cleaning equipment such as heat exchangers, evaporators, tanks and other industrial equipment using clean-in-place procedures and a pre-treatment solution prior to the conventional CIP cleaning process. The pre-treatment step improves the degree of softening of the soil, and thus facilitates its removal. The pre-treatment solution can be a strong acidic solution, a strong alkaline solution, or comprise a penetrant. A preferred strong acidic solution is an acid peroxide solution. In some embodiments, the pre-treatment may include no strong alkali or acid ingredient; rather, the penetrant provides acceptable levels of pre-treatment.

  • Compositions and methods for mitigating corrosion of applied color designs
    Patent number: 6835702
    Abstract: The present invention relates to compositions and methods for mitigating corrosion of applied color designs on a bottle, or on another glass or ceramic item. More specifically the composition or method of the present invention can mitigate corrosion even in the presence of a known corrosive agent. The composition and methods of the invention employ one or more phosphates and one or more phosphonates at a ratio that reduces or minimizes corrosion of an applied color design.

  • Peroxy acid treatment to control pathogenic organisms on growing plants
    Publication number: 20040068008
    Abstract: A method of using peracid/acid compositions, where the mole ratio of acid to peracid is less than about 3:1, to treat field or greenhouse grown plant tissue, seeds, fruits, and growing media and containers is described. The peracid/acid system can lower the natural, plant pathogen and human pathogenic microbial load resulting in less waste to molding, spoilage, and destruction because of pathogenic poisons.
