The number of CLEAN-UP BALLS required is based on the severity of the problem being encountered
and the volume of water to be treated. In oil tanks, only the bottoms (area below load line) needs to be
calculated to determine the required number of CLEAN-UP BALLS. As a rule of thumb, we
recommend the following treatment on oil tank bottoms with the load line located 14” from bottom;
• 210 BBL – 1 CLEAN-UP BALL
• 300 BBL – 2 CLEAN-UP BALLS
• 500 BBL – 4 CLEAN-UP BALLS
For other size vessels, amounts can be adjusted to treat the water portion of the fluid at approximately 200-400 ppm.
