    Mar 01, 2010 The combination of these devices can reduce the load to the magnetic separation system and enables long-time operation. It was found that the COD value can be currently reduced from ca. 200-500 to less than 100 ppm. It was shown that this system satisfies the requirements to be used as a magnetic separation system for the used wash water of drum

    A process for removing fine particles and particulate from water. The process includes mixing a magnetic ballast, flocculant and water to form magnetic floc, and agitating the magnetic floc in a flocculation zone. A portion of the magnetic floc is collected on a magnetic collector in the flocculation zone. Another portion of the magnetic floc is directed downstream to a setting

    A process for beneficiation of trona includes supplying a trona feedstream that is crushed and dried. The trona is then separated into a first size fraction and a second size fraction. Impurities are removed from the first size fraction using at least one magnetic separator. The magnetic separator includes a plurality of stages. Each stage includes a conveyer system including a

    The earliest mass analyzers separated ions with a magnetic field. In magnetic analysis, the ions are accelerated into a magnetic field using an electric field. A charged particle traveling through a magnetic field will travel in a circular motion with a radius that depends on the speed of the ion, the magnetic field strength, and the ion's m/z

    Magnetic micro- or nanospheres can be separated easily and quickly by magnetic forces and will be used together with bioaffine ligands, e.g. antibodies or proteins with a high affinity to the target. The principle behind biomagnetic separation is the action of a magnetic force on particles in a solution. Even a simple block magnet will exert

    ppm: parts-per million

    ppm is an abbreviation of parts per million. ppm is a value that represents the part of a whole number in units of 1/1000000. ppm is dimensionless quantity, a ratio of 2 quantities of the same unit. For example: mg/kg. One ppm is equal to 1/1000000 of the whole: 1ppm = 1/1000000 = 0.000001 = 1 10-6 . One ppm is equal to 0.0001%: 1ppm = 0.0001%. ppmw
