20、ne, dolomiticML = Limestone, magnesianAIn the softening of drinking water, lime is used alone or with coagulant aids to produce a precipitate that assists in the clarification of water, removal of bacteria, andremoval of hardness. Lime and soda ash may be used together for softening water. The lime

21、serves as a chemical reagent in water softening. The only useful constituentof the lime is the calcium oxide content of the quicklime or hydrated lime capable of reacting with the other chemicals in the water or added to it. Inert material, besidesreducing the value in proportion to its amount, also

22、 makes more sludge to be disposed of for a given amount of chemical action and thus reduces the capacity of theequipment in which it is used. In addition to water softening, lime is also used for color removal and clarification of water.BWhen determining the quantity of liming material for the neutr

23、alization of liquid acidic wastes, use is made of an acid value-basicity factor relationship. Acid value andbasicity factor test methods are in Test Methods C 400.COn a nonvolatile basis.DLimestone analyses are typically reported as carbonate (CO3). The requirement that limestone contains a minimum

24、of 90 % CaO + MgO on a non-volatile basiscorresponds to approximately 95 % CaCO3+ MgCO3.EWastewater treatment plant residuals may be referred to as sewage sludge or biosolids.FAlso see “Standard Guide for Alkaline Stabilization of Wastewater Treatment Plant Residuals” (D 6249).GQuicklime, hydrated l

25、ime, and alkaline by-product materials will raise the pH of biosolids.HIf quicklime or by-product alkaline materials containing calcium or magnesium oxide are used, the reaction with water will generate heat. High calcium quicklime willslake more quickly and achieve a higher total temperature rise t

26、han other alkaline materials, which generally facilitates treatment. Although slaking rate and totaltemperature rise are not part of this specification, they are critical site-specific factors that should be matched to the users treatment objective and technology. The methodsfor measuring the slakin
