Which procedure helps with sludge control in tank cleaning?

Hot water treatment is an effective procedure for sludge control during tank cleaning. The application of hot water helps dissolve and loosen the accumulated sludge and residues within the tank. By using heated water, the viscosity of the sludge is reduced, making it easier to remove. Higher temperatures enhance the solubility of many compounds found in the sludge, facilitating a more thorough cleaning process. Additionally, hot water can help in breaking down emulsified materials, which contribute to sludge formation.

While other methods such as inert gas flushing, routine inspection, and chemical treatment have their roles in tank management and maintenance, they do not specifically target the physical removal and breakdown of sludge as effectively as hot water treatment does. Inert gas flushing is primarily used to displace flammable vapors and reduce the risk of combustion, rather than to clean sludge. Routine inspections help in identifying issues early but do not directly assist in sludge control. Chemical treatments can be beneficial for specific types of residues or contaminants but may not be as universally effective as hot water treatment for all sludge types.
