Tank Sweeping Services

Magnetometers have been used in the environmental field for locating buried steel drums, tanks, pipes, and iron debris in trenches and landfills. The magnetometer can only sense ferrous materials such as iron and steel; other metals like copper, tin, aluminum, and brass are not ferromagnetic and cannot be located with a magnetometer. Where buried magnetic objects are present, an audible alarm is triggered as the instrument is swept along the ground surface.

Industrial Tank Cleaning

Employing professionals to help a business correctly maintain its tanks always is a good idea to ensure proper industrial tank cleaning of all your equipment. Running a business day to day is challenging in and of itself, especially when it comes to operating and maintaining your facility. Remembering to schedule maintenance checks on a regular basis and exercising proper care for your equipment is particularly important but it may often be the last thing on your mind. Let Dover help you to manage this process!

Industrial tanks serve many different functions and hold many different types of liquids. They require cleaning on a regular basis to prevent foreign bacteria and fungi growth as well as the buildup of slurry and other inorganic materials.

Dover Environmental Group will schedule regular maintenance for your industrial tank. No matter what your tank is used for, it needs to be cleansed consistently. The growth of bacteria and fungi can cause serious health issues and can contribute to the spread of disease. Very often sludge and other alluvial materials will collect at the bottom of an industrial tank and these should be removed regularly with the use of a high-powered vacuum. Additionally, frequent cleanings can help protect your assets by extending the life of your equipment. Call Dover today!

Acid Neutralization Tank Maintenance

The Neutralization Tank is a collection device that takes acidic waste materials that are collected and passed through this “neutralization” tank system before being discharged into a common sewer system. The waste is chemically neutralized utilizing limestone materials. The limestone breaks down over time and needs to be replaced every 24 to 30 months.

Acid neutralization tanks are frequently found in hospitals, schools, or any other facilities that are required to neutralize laboratory wastewater. As mentioned, periodic maintenance involves the elimination & disposal of spent limestone chips, tank cleaning, and replacement with new limestone chips.

Dover Environmental Group provides the complete cleaning and recharging of acid neutralization tanks in accordance with manufacturers specs.
