Contents Notes |
"Lime is one of the most widely-used chemicals for wastewater treatment. It is marketed either as quicklime (CaO) or hydrated lime (Ca(OH)2). Quicklime is hydrated in a slaking process before it is used as a process chemical. Lime is generally added to treatment processes as a slurry. Lime is used in wastewater treatment for chemical coagulation of solids, phosphate precipitation, pH adjustment, and chemical stabilization of sludge. Numerous problems have been experienced with lime handling systems. These problems affect the performance of treatment processes, resulting in poor effluent quality, and increased operation and maintenance costs. A comprehensive evaluation of selected advanced treatment (AT) facilities utilizing lime treatment processes was recently completed with the objective of identifying common problems associated with lime handling systems. This brochure briefly summarizes the causes and impacts of these problems, and offers suggestions on how to solve them or at least mitigate their impact."--Introd. |
