Once mixed, how long does the sludge remain in suspension?
Only 3 inches of the approximately 3 feet of sludge that was resuspended in a 500,000 barrel crude oil storage tank, at the Gulf Trans-shipping Terminal in Bantry Bay, redeposited in one month s time. In addition, oil samples taken every 2 metres, one month following the operation of the P43®, indicated that there was virtually no restratification of the tank contents based on BS and W analyses of these oil samples.
