In manufacturing, processing and many types of industrial applications chemical waste liquids are produced as part of the process. This chemical waste is highly corrosive and harmful, so it is essential to have a safe, approved and specialized way to rid the liquid of any toxic, harmfully or corrosive compounds. Neutralization tanks can be installed to complete just this task, allowing you to then dispose of the neutralized liquid as per required by local, state or federal requirements.
Neutralization tanks are made out of materials that are chemically resistant so there is no worry about corrosion or damage due to exposure to acids, alkalies and other waste materials. Smaller units that are used in medical facilities or laboratories may be all one piece to avoid any possible areas of leaks or stress with the tank. Large neutralization tanks used in industrial and manufacturing types of applications are carefully constructed and welding and then lined with chemically resistant liners.
How They Work
Neutralization tanks operate by allowing the liquid containing the harmful compounds or chemicals to pass through a specific type of medium. This medium will vary based on the particular compounds contained in the waste liquid. Options include limestone chips, specific liquid chemical treatment compounds or granular additives.
In some specific chemical reactions during the neutralization process heat and gases are created. Neutralization tanks can be constructed with safety venting as well as added heat exchangers to help to keep the tank cool during those chemical processes.
Maintaining Neutralization Tanks
Top quality neutralization tanks are designed to be virtually maintenance free. However, it is important to routinely inspect the tank to check for any build-up of materials in the bottom of the tank, in the form of sludge or slurry, which should be removed on a regular basis.
In addition the neutralization medium will need to be changed out on a specific schedule. This schedule will vary based on the amount of waste material processed through the tank as well as the specific manufacturer’s recommendation or governmental regulations.
Neutralization tanks and systems can range in size from just a few gallons to up to thousands of gallons. Working with a company that has experience in constructing and installing these tanks is essential because of the possible serious health and safety complications if installation or construction is faulty.
