摘要： A method for providing magnetic fluid treatment in which at least one electrical conductor comprising at least one length of an electrical conducting material having a first conductor lead and a second conductor lead is energized. The electrical conductor is coiled with at least one turn to form at least one uninterrupted coil of electrical conductor encircling at least a section of an outer surface of a conduit. Energizing the at least one electrical conductor establishes a magnetic field having lines of flux directed along a flow path formed by the conduit and concentrated in a non-magnetically conductive region located between two magnetically conductive regions. A fluid is directed through the conduit past the non-magnetically conductive region to provide magnetic fluid treatment to the fluid.

摘要： Flowable liquid suspensions are described comprising blends of particulate water soluble high molecular weight polymer flocculants. The polymer flocculants can include polyethylene oxide, polyacrylamide, polyDadmac, Dadmac-acrylamide copolymers, copolymers thereof and combinations thereof. The suspension allows the use of fine powders while reducing potential air quality and safety issues. The suspensions generally settle when mixing is stopped, but a uniform dispersion results when the suspensions are mixed, and the mixed suspensions can be delivered for use. The flocculant suspensions can be used for waste water purification, fiber dewatering, and the like.

摘要： The invention provides a method of inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more particular silane based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.
