What are scales and sludges?

Scales and sludges are solid deposits that form in various industrial processes, particularly in water treatment and cooling systems. Scales are typically mineral deposits that accumulate on surfaces due to evaporation and concentration of dissolved minerals, while sludges are semi-solid mixtures of water, suspended solids, and other organic or inorganic materials that settle at the bottom of tanks or vessels. Both can lead to operational inefficiencies and equipment damage, requiring regular maintenance and removal to ensure optimal performance.
