Abstract: A system and methods are disclosed for treating cooling fluid in a continuous metal casting process having a spray chamber. In some embodiments, the system includes a first compartment with an intermittently operable outlet (e.g., valve) with an open state and a closed state, for removing particulate matter, and a second compartment that receives particle-free fluid from the first compartment. The first compartment may be tapered, conical, funnel, pyramidal shape or otherwise narrowed shape to facilitate settling of the particles. One or more sensors measure at least one property of the particle-free fluid to determine the opened or closed state of the outlet and to adjust chemical additives for the cooling fluid. In some embodiments, the system and methods reduce corrosion in spray chambers.

Abstract: This invention relates to an improved method of inhibiting corrosion and calcium sulfate and calcium carbonate scaling in thermal and membrane desalination processes. The method includes adding a composition having an acrylic acid 2-acrylamido-2-methylpropyl sulfonic acid copolymer, combined with a synergistically effective amount of oligomeric phosphinosuccinic acid to seawater or recirculation brine in a desalting process to produce water for drinking and industrial applications. The method also includes adding a composition including mono, bis, and oligomeric phosphinosuccinic acid adducts to the desalting process.

Abstract: This invention relates to an improved method of inhibiting corrosion and calcium sulfate and calcium carbonate scaling in thermal and membrane desalination processes. The method includes adding a composition having an acrylic acid 2-acrylamido-2-methylpropyl sulfonic acid copolymer, optionally combined with an oligomeric phosphinosuccinic acid to seawater or recirculation brine in a desalting process to produce water for drinking and industrial applications. The method also includes adding a composition including mono, bis, and oligomeric phosphinosuccinic acid adducts to the desalting process.

Abstract: The invention relates to a method of preparing cross-linked enzyme aggregates (CLEAs) comprising the steps of a) precipitating a dissolved enzyme present in a liquid medium: b) cross-linking with a cross-linker, and c) optionally, washing the cross-linked enzyme aggregate. According to the invention at least one treatment is performed chosen from the group consisting of I) performing step a) in the presence of a compound selected from the group consisting of i) a crown ether, and ii) a surfactant, and II) performing step c) with a second liquid differing in organic composition from the liquid.
