    摘要： A secondary polishing process for Bayer Process liquors suspension is described. The polishing process uses a combination of bio-polymers, particularly such bio-carbohydrates as dextran, with an inert insoluble solid, such as a filter aid, to treat the primary red mud settler overflow, then clarifying these treated overflow liquors in a secondary clarifier. Results provide for from 0-20 milligrams per liter suspended solids, often from 0-5 ppm suspended solids, and may make sand filter or Kelly filter operation an option in the Bayer Process.

    摘要： A method for releasing trialkylamines into the dye circulation stream of a dye laser and a filter cartridge containing a resin bound anion stabilizing agent for insertion into the dye circulation stream of a dye laser improves the performance thereof, especially with respect to excimer and flashlamp pumped coumarin and carbostyryl dye lasers. The resin bears quaternary ammonium groups, and borohydride, bromide, hudroxide or chloride may be used as the counter ion. A resin bound borohydride stabilizing agent is capable of releasing trialkylamine into the dye circulation stream and reducing the carbonyl functional groups of polyarbonyl material in the stream to less light absorbing alcohol functional groups. A resin bound chloride stabilizing agent is capable of releasing trialkylamine into the dye circulation stream as a quencher and radical scavenger.

    摘要： The invention comprises a process for improved flocculation of Bayer process red mud-containing slurry. The improvement comprises adding to the red mud-containing liquor a hydroxymethyl diphosphonic acid polymer optionally in addition to the conventional flocculant. The polymer is added to the red mud-containing liquor in an amount sufficient to reduce the concentration of suspended solids in the supernatant phase and/or increase the rate of sedimentation.
