In the papermaking context, alumina sulfate: A12(SO4)3 ù 14H20, A12(SO4)3 ù 18H20, or a mixture of these hydrates The increasing use of alum in papermaking since the 17th century (especially since the introduction of alum-rosin sizing in the mid-1800s, and the substitution of aluminum sulfate for the milder potassium aluminum sulfate about the same time, has been seen as the principal cause of deterioration of books since 1850 [1]; technically, a double sulfate of ammonium or a univalent or trivalent metal but commonly used to denote aluminum sulfate (Al2(SO4)3; a chemical used in water treatment plants to help form a floc (sticky substance) This floc helps remove suspended particles from the water; Added in the drinking water treatment process causing particles to clump together and fall to the bottom of the settling basins; A potassium aluminum sulfate used especially as an emetic; The paper maker alum is hydrated Aluminum Sulfate {Al2(SO4)3} It is used to adjust the pH of the mill water or as a sizing chemical in combination with rosin size; a double sulphate of aluminum and potassium that is used as an astringent (among other things); Phitkari Basic Kitchen Item; A term commonly, but incorrectly, applied in the paper industry to various qualities of aluminium sulphate; or aluminium sulphate A chemical used as a flocculant to aid filtration It produces a floc on the upper surface of the filter bed which entraps particles See also PAC; Phutkari Basic Kitchen Item; Crystals of potassium aluminum sulfate, commonly used in canning before it was discovered that it can cause gastic distress in some individuals Although still considered safe in small quantities, depending on individual tolerance, the FDA (Food and Drug Administration) no longer reccommends its use for home canning Alum is also sometimes used as a home remedy; treating canker sores for example In Chinese cooking, it is one of the ingredients used to make deep-fried crullers; Any one of several aluminum compounds used in pools to form a gelatinous floc on sand filters or to coagulate and precipitate suspended particles in the water; Often used as a mordant when marbling to make the paint stick to the fabric or paper Also used as a mordant for Natural dyes It is a salt of aluminum such as aluminum sulphate; a white crystalline double sulfate of aluminum: the ammonium double sulfate of aluminum; An aluminum sulfate compound used for pools to cause suspended particles in the water to congeal into filterable masses or to fall to the bottom to be vacuumed away; a person who has received a degree from a school (high school or college or university); Aluminum compounds used to coagulate and precipitate suspended particles in water; An aluminum sulphate salt, generally potassium or ammonium is the cation, used to coagulate particles in water treatment; A double sulphate of aluminium and potassium; Graduate of a school, college or university Open Bid - An informal period following Recruitment and extended throughout the academic year where sororities invite young women to parties/events to meet the chapter; Potassium aluminum sulfate - granular form Acts like a magnet transferring Marbling Colors from Methyl Cel base to the fabric; a chemical (aluminum sulfate) used to clarify water, by creating a gelatinous precipitate, that has to be vacuumed to waste Technique is called flocculation; One of several forms of aluminium potassium sulphate which is used in treating leather, in paper-making, and as a mordant to fix dyes in the textile industry Supplies of alum came from Rome until these were stopped in the 17th century by the Pope – because of the dispute with Henry VIII A local industry then sprang up at Ravenscar on the east coast of Yorkshire There was a short-lived alum export industry from Whitby in the 18th century; An astrigent crystalline substance used in rosin sizing to hold paper fibers together; responsible for introducing acid into the paper; aluminum sulfate, commonly called Floc Used to help clarify water Causes small particles to join together so they can be trapped in filter Alum lowers the pH of the water; a double sulphate of aluminum and potassium that is used as an astringent (among other things) a white crystalline double sulfate of aluminum: the potassium double sulfate of aluminum a white crystalline double sulfate of aluminum: the ammonium double sulfate of aluminum; It has twenty-four molecules of water of crystallization; an alkali metal or of aluminium; A double sulphate formed of aluminium and some other element esp; To steep in, or otherwise impregnate with, a solution of alum; to treat with alum; a former student of a school, college etc (alumen). Inorganic compound, any of a class of hydrated double salts, usually consisting of aluminum sulfate, water of hydration (an essential part of the crystal makeup), and the sulfate of another element. The most important alums are those of potassium sulfate (potassium alum, or potash alum, K2SO4Al2(SO4)324H2O), ammonium sulfate, and sodium sulfate. Alums occur naturally in various minerals and can be prepared and purified by crystallization from their solutions. Most are white crystals with an astringent, acid taste. They are used as paper-sizing agents, flocculating agents in water treatment, mordants in dyeing, and in pickles, baking powder, fire extinguishers, and medicines; A double sulphate formed of aluminum and some other element (especially an alkali metal) or of ammonium; {i} double sulfate (Chemistry); alumen
