Disclosed are microwave assisted methods and systems for decontaminating a variety of contaminated surfaces. The systems and methods comprise treating the surfaces with benign chemical formulations followed by exposing to microwave irradiation for short periods of time to achieve at least 6-log reduction in biological contaminants including spores of B. anthracis, B. thuringiensis, and P. roqueforti. Chemical formulations may comprise copper (II) chloride in water. The formulations may include a surfactant such as a polyethylene sorbitol ester surfactant.

The invention provides to a powdered composition of additives and a method of use thereof for increasing the visibility, potency and coverage of disinfectant solutions, such as bleach.

A method of cleaning a cooling water system is disclosed. The method may include contacting a cooling tower fill with a composition that may include a surfactant and an additive selected from an oxidizing agent, an acid, and any combination thereof when the cooling water system is off-line. The method may include contacting a deposit in the cooling tower fill with the composition. The oxidizing agent may be hydrogen peroxide, sodium hypochlorite, chlorine dioxide, ozone, sodium hypobromite, sodium or potassium permanganate, or any combination thereof. The surfactant may include a C.sub.8-C.sub.10 alkyl polyglycoside and a C.sub.10-C.sub.18 alkyl polyglycoside.

Methods and apparatus for remediating buildings damaged by floodwaters. The methods include removing floodwater-damaged wall cladding to expose underlying structure. Applying under pressure a chemical composition to remove malodor and that penetrates into the underlying structure. Then, allowing a powdery surface coating to form on surfaces of the underlying structure. Useful apparatus includes a container configured to contain a liquid phase of a chemical composition and a pressurized gas canister associated with the container for supplying gas under pressure to a fluid conduit extending from an inlet of the container to an outlet of the container. The apparatus can include a venturi in a flowpath of the fluid conduit which suctions a chemical composition in the container into the fluid conduit for expulsion from the outlet of the container and into a high pressure spray delivery hose.

The present invention generally relates to a removal composition and process, particularly useful for cleaning ceria particles and CMP contaminants from microelectronic devices having said particles and CMP contaminants thereon, in particular microelectronic devices having PETEOS, Silicon Nitride, and Poly-Si substrates. In one aspect, the invention provides treatment of the microelectronic substrate having ceria particles thereon utilizing complexing agents free of Sulfur and Phosphorous atoms.

Formulations, methods using such a formulation, and systems encompassing such formulations and methods for reducing energy and/or water usage in an institutional laundry is provided. Such formulations, methods and systems allow for textiles and fabrics to be effectively washed even at temperatures as low as 20° C. A prewash formulation includes a surfactant enzyme booster with the surfactant enzyme booster having one but preferably more enzymes and one or more surfactants. The enzyme of the prewash formulation may include any one or more of a protease, a lipase, an amylase, a cellulase, a mannanase, a pectinase, a peroxidase, and a gluconase. A main wash formulation is used in a wash phase cycle of an institutional laundry where such a main wash formulation includes a bleach, bleach enhancer, a chelating agent, an anti-redeposition agent and/or a soil suspension agent, a surfactant, preferably a nonionic surfactant and an anionic surfactant, a solvent including an aqueous solvent and perhaps an organic solvent, and a builder. An institutional washing process using the formulations provided here are distinguished by the need to only include one rinse cycle—i.e., a rinse cycle between the prewash cycle and the main wash cycle is generally not needed or, at least, a full rinse cycle between the prewash cycle and the main wash cycle is not needed. The formulations, methods and systems provided reduce energy and water usage in an institutional laundry.

A bleaching apparatus has an immersing vessel for immersing clothes in a chemical liquid, and a light source for irradiating the clothes immersed in the immersing vessel with light. The chemical liquid may include an oxidizing agent or a reducing agent in a concentration of 3 to 30% owf. The illumination intensity of the light is 10,000 to 70,000 lx.

The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.

Alkaline sprayable aqueous compositions for cleaning, sanitizing and disinfecting are disclosed. In particular, the sprayable compositions include an inverse emulsion polymer for modifying the viscosity of the composition and provide numerous benefits over dispersion polymer compositions used for rheology modification to reduce misting and respiratory inhalation of cleaning compositions. Compositions and methods of cleaning using the compositions having reduced amounts of airborne particulates of the composition during spray applications are provided.
