Lime Slaking Systems | Chemco Systems
Lime is used in both municipal and industrial processes to improve water quality, by either controlling pH, removing impurities, or softening water. In systems that demand large quantities of lime, quicklime is ideal as the density is twice the density of hydrated lime, which reduces the storage and transportation costs.
