Variables that affect quality of lime slurry produced in lime slaking reaction

Lime is an inorganic compound also known as Calcium Oxide. It is used as a coagulant (charged solid that helps remove smaller particles from water). It is also used as an acid neutralizer. The purpose of this research project is to quantify the use of lime for lime slurries and lime slaking applications. A lab test for lime slurry reactivity will be developed as a part of this project. Compounds affecting the slaking reaction and rate will also be examined and quantified. The main objective is to determine if slaking temperature can improve the chemical properties and reactivity of lime. The expectation is that the required amount will be less than what is currently used. Being able to communicate with industrial users the quantity of lime required will allow users to reduce their consumption of lime which will save money. Indirectly, industrial users will also reduce their carbon footprint because less lime will need to be transported.
