Lime Slurry and pH Control | Red Valve

Lime Slurry and pH Control. Lime is used in many wastewater treatment plants, where it is added to the influent to maintain a optimum pH level. Lime is normally stored as a dry powder and mixed with water or additional chemicals to create a lime slurry that can be pumped through pipes and added to the waste stream as needed.

AN OVERVIEW OF LIME SLAKING

A slurry slaker generally uses an initial lime to water ratio of 1 to 3.3 to 1 to 5 depending on the make of equipment and quality of CaO and water. Typically, a slurry slaker, sometimes called a detention type slaker, is comprised of two chambers. The first chamber is called the slaking chamber where lime and water are mixed.

Next, the lime slurry is combined with soda ash (Ca(OH) 2) + Na 2 CO 3). This yields caustic soda and limestone (2NaOH + CaCO 3). The limestone from this reaction can be recycled to make lime. Soda and caustic-soda solution are essential ingredients in an array of industrial operations. These include pulp and paper and glass making, water ...
