When should you begin to pump out slops during the Butterworth cleaning process?

Pumping out slops during the Butterworth cleaning process is an integral part of ensuring that the tank is properly cleaned and that any residual slops are removed efficiently. Starting the pumping as soon as the cleaning process begins allows for the immediate removal of dirty wash water and sludge. This proactive approach helps to minimize the amount of time that contaminated materials remain in the tank, which can help prevent issues such as sludge build-up or potential contamination of clean areas.

Initiating the pumping of slops early in the process also allows for a more effective cleaning operation, as contaminants are consistently being removed as they are dislodged by the cleaning process. Keeping the tank environment as clean as possible throughout the cleaning operation ensures that the final results will meet safety and operational standards before the tank is returned to service. This method is essential for maintaining the integrity of the tank and adhering to environmental regulations.
