Profile: DV Howells Ltd. is a provider of effective solutions to a wide spectrum of hazards. Our services include tank cleaning & separation services, installation and de-commissioning services, marine and salvage support services, petrol station de-commissioning, marine, and port services. In our tank cleaning & separation services water used in the process is passed through a separation system to remove the waste oil, thereby allowing the water to be re-used. Some of the waste products can be cleaned and processed to become a re-saleable product, therefore limiting the amount of special waste to be disposed of. Using our oil/waste separation systems allows us to offer a total tank cleaning and oil recovery package, thereby reducing the total cost incurred by the user.
