Milk of lime is widely used in various industries such as construction, agriculture, chemistry, food processing, and industrial and municipal wastewater treatment. Industrial preparation of milk of lime involves mixing water with hydrated lime, lime hydrate (Ca(OH)2), or calcium carbonate (CaCO3) using specialized vertical agitators placed inside tanks with volumes ranging from 1 to 50 m3.
Vertical agitators for lime milk preparation and storage must allow for the homogeneous suspension of lime in water, avoiding clumping or powder precipitation. The process is far from simple. To keep the solid component constantly suspended, you need vigorous and consistent agitation, which can be provided only by carefully designed agitators.
Another crucial factor is the concentration of milk of lime during preparation: the higher the concentration, the greater the installed power required. PRO-DO-MIX® vertical agitators, leveraging the expertise gained from hundreds of applications, can handle even very high concentrations, up to 40%: such cases are encountered especially in Northern European countries, which adopt different preparation techniques.
In designing and manufacturing our agitators, we combine experience and innovation: we rely on specialized professionals and advanced 3D design and simulation software, used in every project to provide our customers with excellent and reliable agitators.
One of the main areas of lime milk usage is in the purification and treatment of industrial and municipal water, where this preparation plays a crucial role. It can be used as a coagulant agent, pH corrector to raise the pH of wastewater, to precipitate metals or for remineralization, which is necessary after reverse osmosis processes.
All water treatment and purification processes require tailored and high-quality agitation solutions. At PRO-DO-MIX®, based on numerous successful projects worldwide, we have developed a complete range of vertical agitators and impellers covering the needs of various water treatment stages, including flash mixing and flocculation.
