Sludge & Tank Cleaning, Oil Recovery

Upon entry, the stream is split between two lances and the tank is quickly and thoroughly cleaned. To reduce the volume of water required, we use a unique micron-filtration system that allows us to filter the water generated and reuse it in the cleaning process. Doing this drastically reduces the amount of water used and contributes to the overall cost-effectiveness of the project.

Desludging is the first process in the cleaning of the tank and this is where most of the oily sludge from the tank is removed. The desluding process may begin when the oxygen level has fallen below 8 per cent. The nozzles are operated one at a time, alternating between all of the nozzles supplied with the system. Since the sludge may contain solids, water and trapped, liquefied oil it may be necessary to add cutter stock to re-liquefy the sludge.
