A milk of lime preparation station is a specialized plant used to produce milk of lime from quicklime (CaO) or slaked lime (Ca(OH)₂). Milk of lime is used in industrial water treatment processes, particularly in the neutralization of wastewater, the precipitation of heavy metals and the stabilization of wastewater.

Technical background

Milk of lime is produced by the controlled mixing of water and lime. The process involves two main steps:

  1. Hydration of quicklime
  2. Suspension:
    The slaked lime is dispersed in water to produce a homogeneous milk of lime. The concentration is typically between 5-15%.

Construction of a milk of lime preparation station

A typical milk of lime preparation station includes:

  • Preparation tank: For holding the lime/water mixture, equipped with agitators.
  • Dosing system: For precise control of lime addition.
  • Measurement and control technology: level measurements and flow regulators ensure the efficiency of the process.

Applications in practice

  • Neutralization: Milk of lime is used in wastewater treatment plants to neutralize acidic wastewater.
  • Heavy metal precipitationHeavy metals such as zinc or copper are removed from the water by forming sparingly soluble hydroxides.
