Methods and systems are described for providing improved food processing systems by treating wash water in a wash stage of the food processing system with a biocide. Sufficient biocide may be added to significantly reduce the levels of bacteria in the wash stage, which can prevent problems associated with bacteria in downstream processes.

Stabilized compositions employing a sequestrant system and a binding system for improving shelf stability and dispensing stability of a solid activated bleach composition are disclosed. The compositions contain a peroxygen source and a catalyst activator which require generation of a peroxycarboxylic acid or other active oxygen sanitizing agent at a point of use. Stabilized compositions employ a sequestrant system including a phosphonic acid and/or dipicolinic acid sequestrant and a binding system comprising an anionic surfactant for a solid formulation of a catalyst activator and peroxygen source to provide shelf stability and dispensing stability for a activated bleach composition. Methods of formulating and use are further disclosed.

The present invention relates to compositions and methods for the remediation of contaminated solids and liquids. In particular, embodiments of the present invention relate to the bioremediation of solids and liquids by a composition comprising a biocatalyst or mixture of biocatalysts. The present invention also relates to methods for producing the bioremediation compositions and methods for applying the bioremediation compositions to contaminated sites, including treatment, storage, and disposal facilities, as well as various contaminated water sources, such as aquifers and reservoirs.

The present invention is a water treatment agent containing (a) a polyalkylene oxide with a weight average molecular weight of 500,000 or more and (b) an inorganic flocculating agent.

The present invention provides improved methods for purifying and/or removing oily particles, and/or contaminants suspended or dissolved in water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing an oil phase from an oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is combined with surfactant in appropriate ratios to facilitate oil removal for water purification in any of a number of commercial, environmental and industrial applications.

Provided is a composition for interfacial polymerizing polyamide including an amine compound; and one or more types of compounds selected from among a purine-based compound and a pyrimidine-based compound of Chemical Formula 1: ##STR00001## wherein, in Chemical Formula 1: X is N or NH; Y is O or OH; Z is O, OH or NH.sub.2; R1 and R2 are each hydrogen or a substituted or unsubstituted alkyl group; and is a single bond or a double bond, and a method for manufacturing a water-treatment membrane and a water-treatment membrane using the same.

A system for use with contaminated land comprises: a region defined by or within the land, the region having a plurality of locations defined therewithin; at each location, one or more apparatus selected from the group comprising: sensor, well, electrode, cathode, injector and vent; an array of photovoltaic cells for producing DC power; a ground-mounted frame supporting the array, the frame having a boundary substantially contiguous with the region and supporting the photovoltaic cells; a fluid distribution system of conduits supported by the frame; a power system for delivering DC power to each of the locations; and a communication system adapted to provide for remote control of the apparatus.

The subject invention provides methods for improving the treatment of effluents and waste matter produced during food processing and production. In particular, the subject invention provides methods for remediating fats, oils and greases (FOG), suspended solids, proteins, and other organic matter that are discharged from plants that process, for example, meats, poultry, seafood, dairy and plant-based oils. The methods of the subject invention utilize a customized microbial cocktail comprising facultative anaerobes, in combination with one or more microbial growth by-products, e.g., enzymes and/or biosurfactants, to digest and/or liquefy food processing waste matter.

The present invention is a water treatment agent containing (a) a polymeric flocculating agent, (b) an inorganic flocculating agent and (c) a surfactant, wherein the water treatment agent contains (c) in an amount of more than 50 parts by mass and 10,000 parts by mass or less relative to 1,000 parts by mass of (b).

A method of remediation of a water-bearing formation is disclosed. A first solution containing a nitrogen-containing compound and a second solution containing a nitrite-containing compound are introduced into the water-bearing formation. The two solutions intermix within the formation such that a foam is generated within the formation.
