Tank Cleaning Basics

Whether it is time for an internal inspection, you discovered an issue with your tank, or you are simply in-between steps in a production process, a thorough tank cleaning is a necessary first step. If handled incorrectly, this process can be disastrous for the safety and success of your business.

The best way to ensure your cleaning procedure goes well is to brush up on a basic understanding of tank cleaning technology and work with the professionals. In this blog, we will explore the basics of cleaning you tanks, and provide resources to a wealth of in-depth information.

The Four Fundamentals of Tank Cleaning Technology

The basic fundamentals of tank cleaning can be broken down into four key parts. The importance of each individual part will vary, depending on the type and requirements of the job, but all can be understood through an illustrative tool known as the Sinner’s Circle.

The Sinner’s Circle is divided into the following categories:

• Chemistry
• Mechanics
• Temperature
• Time

Chemistry relates to the choice of cleaning agent. The type of cleansing agent you use depends on a wide assortment of factors, including the degree of soiling inside the tank. Mechanical requirements – or the precise nozzle system utilized – differ based on pressure, friction, and impact. Temperature and time can also vary depending on the type of cleaning job. For a more thorough investigation of each of these factors, read our interview with Bob Garstki, Senior Application Engineer at Lechler Inc.

Advantages of Using the Correct Nozzle System

Modern nozzle technology has come a long way, lending more benefits to cleaning than ever before. Utilizing nozzles eliminates the risks, restrictions, and costs associated with manual tank cleaning. As a result, the cleaning process is trouble-free, repeatable, and verifiable. Additionally, high performing nozzles allow you to save on energy costs.    

Finally, using the right nozzle technology is incredibly important to the mechanical portion of the Sinner’s Circle. By using the correct nozzle for your needs, you can enhance the mechanical piece of the pie while shrinking the other slices. The result is significant, cost-effective reductions in time, temperature, and chemical usage.

Types of Tank Cleaning Nozzles

Different nozzle designs exist to serve a variety of purposes.

• Static Nozzles do not rotate, are relatively trouble-free, and are cost-effective. However, they do require considerably more fluid than other options, best suited for smaller tanks and mild soiling.
• Free-Spinning Nozzles use cleaning fluid to drive the spray head, creating optimum cleaning efficiency at low pressures in small-to-medium sized tanks with moderate soiling.
• Controlled Rotation Nozzles also use fluid to drive the rotating head. However, these nozzles produce larger droplets, important for high impact cleaning necessary for intensive soiling in large tanks.
• Gear Controlled Nozzles sweep the entire tank surface in pre-programmed, model-specific patterns during the cleaning cycle. This type of nozzle creates a regular and repeatable standard for cleaning time and is ideal for very large tanks and the toughest cleaning tasks.

Making the Right Choice:What You Should Keep in Mind When Cleaning Your Tanks

Due to the wide range of unique options in the nozzle industry, it is important to consider the following factors when deciding which to use for your tank cleaning process.

Hygiene Requirements

What unique hygiene requirements do you have? This can be influenced by what your tank is used for and how often it is used. Before beginning any basic tank cleaning project, it is crucial to fully understand these requirements.

Material Needs

What types of cleaning chemicals do your nozzles need to be able to withstand? Different materials are required to fight against resistance and wear. Additionally, food-grade materials for beverage, food, and the pharmaceutical industries can vary greatly.

Cleaning Efficiency

From a simple rinse to extremely difficult soiling, nozzles are designed for every cleaning need. Be sure to take factors such as tank size and recommended operating pressure into account.
