Scale in pulp mills is a term used to describe deposits or coatings that form in equipment and pipelines during the manufacturing process of pulp. These deposits mainly consist of undesirable substances such as calcium carbonate, calcium sulfate, and other minerals naturally present in the water used in the process.
The causes of scale include minerals present in the raw water, chemical reactions occurring during the process, and water evaporation from the process, leading to a concentration of minerals and the formation of precipitates.
Scale can pose a problem in pulp mills as it can cause equipment and pipeline blockages, resulting in reduced efficiency and increased maintenance time. Additionally, scale can affect product quality and lead to increased production costs.
Various methods are used to manage scale, including chemical treatment to prevent the formation of deposits, mechanical cleaning of equipment and pipelines, and the use of water treatment processes to reduce the mineral content in the used water. Effective scale management is crucial to ensure smooth operation and high production quality in the pulp mill.
