The commonly used neutralizing agents are limestone, soda, sodium hydroxide, fly ash, etc. The process of lime neutralization + three effect evaporation is adopted. Limestone is used as neutralizing agent to improve the pH value of waste acid, forming the coprecipitation of calcium sulfate and metal hydroxide.

The preferred method for pH neutralization of waste streams is by the automatic addition of ,acid, or caustic. The ideal setup is a batch neutralization module. A basic batch system includes a treatment tank with a mechanical agitator (mixer), an in-tank pH sensor, an in-tank level control, metering pumps for ,acid, and caustic injection, an automated drain valve or pump for the effluent, and a control panel.

22/2/2016, · Since ,limestone, is widely available in Karbi Anglong and nearby areas of Assam and is also cheaper than the other materials, it may be the ideal choice for neutralization. Ideally the material should be added at the storage pond with facilities for continuous stirring and agitation (so that the base quickly interacts with the acidity) and the neutralized water should go to circulation.

Limestone is one exception, it is the most inexpensive of the common acid neutralizing reagents, the only problem with using limestone is that it will coat (armor) with iron hydroxide precipitates in the presence of oxygen (Nairn et al). This armoring of the limestone slows the dissolution rate of the carbonate and reduces the buffering effects of the
