  • How a Thickener Works - Mineral Processing Metallurgy

    Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...

    The flotation process in sludge thickening is in principle similar to the flotation for pretreatment of wastewater. In the flotation process, air is injected into the sludge tank from the bottom under pressure and a large amount of air bubbles disperse into the sludge, attach themselves to the sludge solids and float them to the surface of the ...

  • How Starches Thicken Sauces and Fillings Kitchn

    May 21, 2015  The reduced movement results in thickening and is the beginning of the gelling process. As more heat is applied, the starch granules eventually begin to leak, freeing the starch strands from each other. At that point, the liberated starch strands are free to interact with and trap water in a process known as gelling or gelatinization. ...

  • Dissolved air flotation - Wikipedia

    Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter ...
