What is the most common problem encountered with lime slurries?

The issue of plugging of the lines is indeed a prevalent problem when it comes to lime slurries. Lime, particularly when mixed with water to create a slurry, can have a tendency to settle out of suspension if not maintained properly in terms of agitation and flow. When this settling occurs, it can lead to the solid particles accumulating and clogging the pipes or other components of the system.

This plugging can be exacerbated by various factors, including the concentration of the lime in the slurry, the temperature of the mixture, and the design of the piping system. Ensuring proper flow rates and maintaining adequate mixing are essential to prevent this problem from arising. Addressing plugging is crucial because it can lead to costly downtime and maintenance issues in wastewater treatment facilities.
